Catching fire: How Cooking Made Us Human with Richard Wrangham

Catching fire: How Cooking Made Us Human with Richard Wrangham


Music. Are you study was cooking the cost the extraordinary transformation over ancestors from a black to home or practice. What the heart of this episode lights in the explosion of new idea the habit of eating coach rather than permitted that i just of track to shrink on the human brain to grow help structure human society and created male female division of labor. Is their ancestors adopted to using fire humans emerged as the cooking apps covering everything from food labeling food. Catching fire offers a starting original argument about how we became to be the social intelligence and sexual species we are today. The fundamental question that every culture answers in a different way but only science can truly decide i want today’s gas deeply explored is what made us human. Our guests were proposes a new answer. Is that true change my driven by curiosity and beliefs the transformers of moment i gave rise to the home of one of the great transitions in the history of life stand from the control of fire on the advent of cooking meals, we welcome the author of catching fire. Okung made of human richard bryan welcome to the show will thank you very much in nashville with you before we explore the origins of us as humans at all we should go to original right back to menu research student with jane goodall yes i hardly drink good fortune to spend, you’re working as a research assistant in mumbai national park in tanzania was jane goodall was doing how to plan vacations. Another results of that, yeah i was able to go back and do my phd the feeling behavior option so i just want everything coupons i made a big impact on me, yeah loads were you talking about sometimes you forget to bring your sandwich is a hundred so you’d just name it that feeling habits of the bones and i was the driver of this curiosity that logic in the spring piece of work, yes i don’t want to climb too much you know cuz what happened was that who we are without closest living relative in an environment in which they are, doing well eating food stuff on the how is it possible to eat without feeling too sick. I’m a little bit noches the last mri i would sometimes have holiday because i forgot to take food with me i’m so i did survive on what the plans for evening that’s me and what i realized was that it was something i could do nothing i just, i was so happy in the evening to come back and eat a big bowl of mashed potato pasta or whatever it would be, another the reason i say that i don’t want to play in to much is that took me something like twenty years old the penny drop tonight though you know what the big difference to what she meant was reading what i meeting headset the role wasn’t good with let’s explore that dropping moments because you bring the spring resort the cover so much as i mentioned in the intro i don’t know if he gave us a brief overview of our fossil record in ND the transition, first signals two point six million years ago but sharp flakes dog from ethiopian rock, i need a big story of human evolution is that. What about two million yeah just a little less than two millimeters, we have had ancestors looked like in the sense that they are upright about the size, and what could not very good at climbing hello basic i shape so how the words you could imagine them going down main street and be able to walk into a clothing shop and get clothes off the peg to fit them. Nope of them are ancestors were, i certainly able to walk upright lamp not doing so and only one ever on the ground it was so good at climbing so they had much stronger arms and shoulders i’m they would like a chimpanzee standing upright. This is a huge difference in the difference is marked by calling us regina homo. Initiate how a director so maybe homework have a blessed i know how much until recently until about two two hundred music out. Set up a question though understanding what happened to make us human is what happened to change our best to standing out price. Who is ali primitive kind of human this this happened adjust around two min ago already has you know did there have been some use of stone flakes, oh douglas a variety of activities we included my cousin some meat off bones are but probably also the shipping wouldn’t steaks episode of saying hold the toulouse kim. Bust a van later, run two millimeters ago we became the first members of the genius IMO not question is why nancy say according to the most popular of you since the nineteen fifties there was a single supposed to do which was the evening of may, people rested how to not one but evidence of cooking was badly adaptations for example last step climbing training shoulders intestines brain evidence play a sleeping on the ground not in caves and. The only way to do that that you discovered was fire yes i think there are two big reasons for thinking that i must of been the critical breakthrough control that made us human i won’t is the one you mentioned which is that that point we become committed to sleeping on the ground because is quite clear that we could not do what champions is. Rose i was eggs to which is yes i need to climb a tree is to be able to sleep in when we’re lost those climbing adaptations then we can also host a sleeping in the area on the ground that would be extremely dangerous i mean nowadays you just awesome just. Going to sleep and the surgeon guess your your someplace follow a community you coming to go last night. I’m just lying down on the ground at night with no fire is also terrifying. What happened turn the when you got someone that you be prepared to sleep on the ground in the second big reason why is what happened with the god, i wanna see the guards i mean all the way from. What are my house and threw our digestive system what happened. That’s everything got smaller. Hey. The mascot small not to small or i am to judge from the arrangements of the barnes and the actual i got the intestine of the cambridge used by may be as much as i ask god. And some people have you that’s got something to do with me but other changes in the shape of the teeth are already done because they were so small and. Turn around and i know quite unlike what you see in i. I got to read seven hundred eight bayshore sharing teeth. And um these the only reason explanation lol what happened wednesday, i got as amazon spy the bones emma teeth is not really eating soft, you just include in the resume oh i’m kind of food that would be it is good that was correct what is combination of commitments to sleeping on the ground and commitment to eating softer just like food i think speaks very strongly to the fact that, this mr b in the time out which humans became able to control so i so project play that they could adapt to using it want the reasons for saying that. Is the whenever this happens whenever humans did learn to control file an injunction protect the way the whole waze. I didn’t know question one he would you find some other biology i’m what’s your first name so there is no subsequent time subsequent to two million years ago i when this, is signal and other words there is no point to which i cannot submit changes in a way that suggests that all the sudden we stopped eating real food and cook food too many ideas ago will the evolution of how the raptors. Is really a time that it very difficult to see how you could be anything on the point. When our ancestors post control and that meant that he became what i love about this is. Where in the world of technological change and fire was a technology and had a massive impact on society not only physically for people are allergic, what also on the impact on society itself where we operate for example i love the way you ride this dick seismic shift square table but one for me for example when i caught this from the book. Team mark might of been necessary with some individuals in hunting party throwing rocks to keep my animals up bae when others quickly cut off from shirt made before all retired to eat in a defensive outside so it’s easy to imagine that the rise of meeting faster, where is human characteristics such as long distance travel bigger bodies rising intelligence and most importantly increase corporation. I want something that were seen in society today driven by technology. There is a need for more cooperation in competition in a world of increasing complexity i really like that. Comparison that we see there love you talk is true for example them and the hunter hi pot this is what i was incomplete me the link future that is missing in the whole idea of meeting. Is the one not adopted to eating meat raw if you actually do a survey to the number of people who beat the metro people living in, samsung arizona small scale society you are essentially the only people ever do it and even that’s very rare is in the object, we’re cooking is tremendous suggest a cold and what happened is the man who. Are hunting for a day go to crash while they have previously getting some food to get up and get some of the main when they get home in the evenings absolutely insists that i will have produce, the great sioux for a row store number is a coat and paid for the slowly steal over claims. Are you going to the shop it’s nobody averaged me to draw unless good reason so that it’s both roll that we always miss techno on time and costs dangerous because bacteria can you delete gonna turn dangerous for you. This means that, two things that humans could be in where adopted two meeting road to being able to cook and it’s impossible to imagine ready and then you talk about how long a person find meds after spending all day long but there cheering for a very long time. I’m you say this is kind of akin to arrived yet because you’re cancelling because you constantly hungry because there’s a lack of energy from that food yes i’m so fascinating you know that when we compare thoughts with those the prime needs people often said well you know we can eat fruit weekend eat meat so we can we can i need almost everything we doing we can eat raw are there and so why do we do that will the answer to do that and that is that it takes a tremendous amount of time, when can we go out the seat opens for the first time know what the hoping to do is to see some of the past videos of asians account for jane goodall and others that using who’s the drinks with all of anti-social things actually book a time when you see it is there anything. Because if you a community controlled wild food in order just to get enough calories per day. Species like humans, you have to spend many hours per day turn like people. Where is that i still didn’t with jane goodall they are shooting the earliest to in about six hours per day. If you look at. People around the world weather they are and USA europe or in small scales in celsius how does got the runs you find the same thing but just that people that really you less than already. That’s because. The food is good and this is often beasley massdrop is just very different with a real food who is many people. Hello any idea about ross goodwin has what they think on its things like apples and bananas which are the projects all culture. You know people say bananas are nature is perfect food in the wrong. Because bananas are couches perfect food that the results of the selection by people for food that has been, developed and evolved as a result of artificial selection is humid, why was you find that they are they are full and find strains are often wrong or strange and two other kind of difficult tasting come felons i’m not results is the new up to spend a lot of time feeling a way to get a little value. Oh no they’re huge difference i want to hear your, good coach and a basic humans we will be saving our soles of the day probably five six seven hours a day of chilling what are the differences in may choose what we can do in life you been venting all sorts of technology you can be single weapons you can read going out of control you can take risky when she’s spending all day trying to get me some donuts or succeeding yes, you have all this free time uploaded. When the fact that you put your food in the view of many evolutionary. Anthropology is the pressure for intelligence comes from, the advantages of a wedding social competitors where is a major reason for species differences is have much brain power the body can afford, i want this is really interesting the fact ask because we had new energy because no had extra calories vs prime example. Our bodies in their wisdom did not energy into being a better climber are having a better digestive system. Energy was powered into the brain two point five percent of value is twenty percent of energy and take so the brain, developed and that’s where we became king of the species so far. Yes your so right to his endearing puzzle as to why is that, the judge from the size of the skulls start singing about two minuets ago just before the light you got a pretty nice continuous rise in the size of the brain and. What we know the density of neurons in a human brains compared to the brands or how close relatives it suggests that the rise in the size of the brand i’m. What is. Pretty much exactly maryland by rise and late number of neurons and the complexity of the networks and all the words i will the things that are associated with intelligence and why did this happen why didn’t that happen with other species this is a machine continuous rise. I wouldn’t say that the answer is fully known yet. But it sure seems as though a critical part of this solution is the question of how you can’t afford to fuel the brain as i was saying because they brian is not only a very expensive tissue. Who did this also heard that issue for you have to continuously fuel if you would stop feeling brain. Then you die was not like the computer didn’t turn the brain off at night in the middle of the activity has to continue. So you have to be able to reserve a portion of, i’m mad about the energy of the body as a whole so the brain and went to many, what is the most interesting lol command because we have a special day brian will it’s big money instead of basically every fifty hamburger you eat is just use for the brain, u twenty percent of your total nutritional intake calorie intake and so the fact that what cooking done. Is to substantially increase the amount of calories that you can take him she was very significant. No one of the ways in which you can think about this is the trade off between the energy of portions to the different parts of the body, got is another pretty expensive. In terms of use of calories but i got something like third smaller than they don cousin apes. I’m that’s because we have evolved the most take advantage of her easily adjusted food that doesn’t require such hard work by the gods. Well that means that we’ll save and also lots of energy that would otherwise go to maintain those gods i’m driving his guts and that energy can be used for making the brian vega. Set the various ways in which you can stink all the consequences of cooking. Will there be reduced need to fuel the garage and it increased availability of energy supporting the brain. No i think one would think if i just the other cooking just got probably a better and more efficiently and producing calories in the last two me the news, we be able to just get continuously think a brain during that time and just get smaller and smaller than one of those benefits with the social alliances cooperation, when does the same os animals no ope two the cognitive challenges of juggling social alliances what’s the exceptions are telling for example you mentioned a link of sociology to mental power found in social i thought this was fascinating you mentioned particularly handsome, yes that’s remarkable in the comparisons can find a cross download kingdom so great pico sociology and the inversion breads is the social event like bounce, bees and wasps and it turns out the day do a portion of big part of their body to the other networks got a little brain turn species at all sociable so they don’t seem to be some kind of road relationship between sociology and grandpa i’m not make sense because in order to be activate social what you need to do is to resolve, individuals that can live together in peace i’m the same time you have tremendous competition among those individuals will. What opportunity to form alliances and help each other and compete many children does ray, the ones just a little bit more intelligent all the ones who are going to be able to succeed an international competition dimensions the variation in god’s eyes which is linked to the quality of dollars but also that large goats take energy away from the brands or the expensive from the perspective which also explains have a brain in good faith, wyd your after rich lunch time meal for example we experience that made afternoon slump this is the bones of the expensive tissue hi bot this is. Expense additional closest is the one that starting in nineteen ninety five when i hello peter la de pointed out of this, inverse relationship do you find among the prime events in general the ones that have the smallest gods of the biggest brands in a pound this logic that i was just re counting, when you can ship the, energy that you will apply god’s if you’re if you need god’s you have to supply them with angie what did you have small glass you gonna shift the energy to some other organ n species sandwich. Social competition is tremendously important because you live in groups when you shifted to was the brain. How do you get a small soy a small gas in species as a result that’s exactly what we owe and richard your mention about real foods and getting less. Let’s energy and in particular dimension the diet i thought this is interesting because in a world where. People are mentioned that being vegetarian hearing alot about this tuesday and netflix documentary called game changes for example they spoken by the lord and that was a bad move into a vegetarian diet. I thought this was interesting in the backdrop of europe because. The energy needed to feed the brain divided by energy expenditure in to justin brought food is really important consideration and hear the jody it showed that third artifacts impacts on the body and reproduction for example when we dont need of calories and we don’t live coach food. Yes what are the new remote control. Things didn’t come to the one i started doing the swap was a resistance to the idea that there is any kind of fundamental difference in calorie gain from eating food cooked eating it raw. What can understand why people are resistant to that so for instance. Remind go to publish nutritional data. If you go to the website of the u. s. department of agriculture. Oh i think it’s a one thousand. Foods i will nutritional characteristics and you can take how’s the food you can take carrots raw carrots the job some quality of some kind of meat you roll a written quote and what your time to find. Is that the data say that you got the same number of calories per gram weather is rome could not the reason that. That is sad is because the way in which calories are index is essentially blowing up the this is done nothing go to mesa. What you do is you assess the number of calories in them made my see what happens when the center is on fire across the great difficulty will those sorts of data is that is not the way that the, do you have the body digest food it doesn’t blue the food up digest by applying. Turn the items i login muscular reaction in the body. But i actually am having you can say maybe twenty five different digestive process is that reduce the jungle food into the molecules that are actually convert into a result in your blood. And the points battle is just a process business they cost energy and if you eat food coach. When did it cost much less for the body to get the nutrients into the blood then if you run. So that is one major future that means. The measurement of calories per gram using a bomb color is another way of accessing the calories of food is actually evening goat vs a second to send out without his consent the cost of congestion. The second reason that would give me a quote. Is more valuable to you than food evening draw is not a higher proportion all of the nutrients are actually just did not when it is eaten quote roy food. Can pass through the body hole lead and just stood in some cases i might start grinding just never. Broken down by the body what the wrong food camp house to the small intestine which is. When the food is done just that most division player and then get into an large intestine which is when all microbiology is there any convert conversion by the micro biome but the thing about conversion by the micro biome is that we only got about half of the nutritional value of the nutrients when they are submitted by bacteria in the micro biome. So if the food is your role when is event is done just in a small intestine more of it is on the ando justin oh. Is comments advisory micro biome in which case we get last value of it. Net result of these process is that. People who all eating enough food turn the raw. Guess soo much less calories from the house that if they are women. I do not have enough calories on average. To be able to maintain my reproductive function once how far do women on a roll food dinners will turn out to stop menstruation. And this is fascinating from the point of you thinking about the missionary biology because that means that cannot reproduce. Means not the rule just not well adopted. This is despite the fact that the roof foods that is rude you were being measured in this way. The roof very high class foods they are the rich agricultural foods like apples and oranges and bananas. Not only that but also is the process very often electric blenders. Do you know who is all so that come from around the world so that, when is new period of the winter of the dry season when they are forced it really low quality foods contain can get the food from whatever is producing the best with that particular season. You know all these wonderful conditions that mean that. We live in the lap of luxury you know these conditions the average woman in the role comments hello baby. So there is a difference in the color i gain that we get from eating food is raw and cooked which means that we are the only species on earth. How does this unique constraint we are adopting the heating up food coach. We cannot survive on eating out in the wild we have become a different kind of species completely reliant. I’m kooking dimension there food labeling i think this is really important too cold out because i haven’t seen it cold out this way that makes absolute scientific sense someone the show we often discussed convention still the used in the world today our right of days for example the extras in the business or management styles. Put a word on nutrition information label and he was use in the book. For more than a century the convention but has dominated estimating energy values and foods and i want to print the food labeling system in the western world has been the water system, when will rohit who invented that was born in nineteen forty four what has to clinical problems that under mine its ability to assess the food value vitamins of lodi just ability, whole grain flour with large part because i thought this was really interesting because. These factors need to be considered we need to update the system in order to consider the way i feel his of his what’s the food is of all three examples. Valley mills flowers the new flowers that we have developed in brad saturdays all have a massive impact for still using the same labeling system developed back in the nineteenth century. Yes when you go into a supermarket and the calories per gram the on the food labels measured without taking into account the digestion of the food will the cost of digestion is so the net result is that you do not realize that, food that is more friendly process still has been no heat treated and it’s production. It is going to give you more calories than fresh original food that is not been processed i just doesn’t come through my finger tragic results one that the results is that. People think that roll food is good enough and dogs well that just means that maybe people get hungry but for children been brought upon a roof food and this is really dangerous, i’m there all cases from time to time where people with the best of intentions bring the children are rude and i’m thinking leaving need some dying from salvation its be against the law good evening will that happening it’s a baby we have a system where people are much more wanna hold the color difference between the role and food eating coach who. Yes we need a new system there are some group said draw some attention to this to weight watchers a tension to the fact that im finally processed foods will if you agree to help me regain because the irony is that for most people. The way in which a un improve knowledge of the calorie density of food do you really know calories in the you got from them the way in which this would help most people, is maya lying them to you account more because so many of us struggle with maintaining weight all trying to reduce it, what are the way weather i was trying to gain weight will try to lose it will be better if we have a realistic system. All informing you shoulda about how many calories even get no food. I thought this was interesting from innovation perspective you said. Researchers know precisely what is a reply to food monica and each point in the journey down the elementary canal, vacancy which chemical bones are separated by which enzyme at which point, how the members carry the product suggestion across the gold wall. Have you call sales respond to changing the concentration, the detail of yo chemical language that is exquisite or not typing into it. For example we could use technology here the whole idea of nano technology. Inside the goes to tell us what food is best for me if i’m digestion that well so you can individualisé and personalised to certain body types that certain digestive tracts all this kind of stuff comes in the form. The way in which the nutritional textbooks think about food is dominated by chemistry. I’m the coolest the chemistry is very important on this wonderful what advances have been made understanding about chemistry what we need tho what is missing from most of these sorts of boats is the by physics. Selena words the domination of this area by thinking about my chemistry is so great that. There is a sense no difference in the perception of equality between how say rome. I’m a solution all. Amino acids and proteins the identical find a comic what you see in the meat will just converted into a liquid. What effect does huge difference in terms of digestion and the color again. Because much of the meat is just gonna be very hard work for the body to digest you gotta break it down into tiny little molecules sprit of at dawn entertain me to go to bills and all that takes work third, in order to be able to understand really how old is. Yes use food we have to think of the physical state in which the food is presented to the body because it has a great impact on hold how many calories we end up getting from the food and one of the things i just want to come back to. What is because we did not to spend up to six hours per day sharing to energy is the body we are now able to enjoy the brain and. You say it was questionable whether the sexual division of labor would’ve been possible that all what they really think it’s because of how long it talk to hunt or together. Did you and i just. What if i hear solve this problem i’d love to delve into this because the springs are sent to the whole sexual division of labor in households sociology called momentum takes a very long time to develop and therefore takes a long time to shift into a whole new momentum. Search address labels seven just think it is dead i will be cooking hazardous with anything other than to say if you survive all the sizes of the world. You find that the domestic cocaine is always done by women are exceptions. When you come to publix aaron is where i am indecisive them and go turn up the day and do the cooler and the fixing the barbecue maybe i’ll join together in the middle of the village. Nothing tastes asleep produce some truth and trust one day today it’s who is the woman who doing the cooking and someone who started the company is. How to know the sexual division of labor is gonna win this tracking because. You might get slight sex differences in what is eating so trump emails but mom made plans a few emails do but there is no division of labor because there is no kind of coordination of think labor. Its not as if a male and a female sheriff a task and combine to produce something together a meal much is what happens in new orleans. Where did this come from i am very impressed by the fact that. Once you have cooking then you have any new kind of problem for the individuals who are organizing the food because. Anybody who cooks enough food and therefore improve that is adorable to having grass would stop loading, and that is because when you look it takes time, enable to compare the feeling batman take ten minutes may take off automatic no longer enjoying what time is somebody else who is bigger and tougher than u coming along i’m finishing the food is on the phone and to make matters worse smoke is the strong smell the easiest for people to figure out when somebody is cooking. Play open google and i think the deep dynamics behind the central division of labor. Involves the fact that men are physically stronger and may be more socially organized and women that the result. Man in a position to be able to take advantage of a woman’s cooking and sometimes c store is this in graphic nature show where the women it is good enough just comes along that i’m done takes food from her phone while she screams at him and objects what happens what happens is that she. Tell her husband that some guy was a bachelor long and i am a husband and talk to the other. Men reveal their husbands and they got together and confront if, i’m willing to mend his ways i need help unless there is gonna be real trouble in any megan speaking of us are you gonna system in which women are beautiful but they have a system of protection. I’m not system of protection i am involved with them being where to use the community husbands as an allowance to protect themselves, once you got this then want the full position because they can’t predict that day come as a result of this alliance lol wives to produce, food golden i’m not mean go off and spend hours per day doing all sorts of other stuff. Another stalker include both contributing to the family needs three hundred but it could be other things as well the girls looking for girlfriends or sitting under a tree gambling oh going off to some religious ceremony somewhere. Whatever does the want to do i make you like to be in some ways because in some ways this is what the hundred storey because. What kind of exploitation by men and women’s labor it’s a story that you see repeated and society of the sizing. I think ultimately it comes from the fact that. Enable people to be very efficient in the production of food also very valuable to these from social competition worldwide pattern of women as the cokecan manas the order is reflected in the english language itself and you tell is this word lady is derived from the old english i’m gonna butcher this workbook. Meeting brad need ur where is the word lord comes from weird which means bread keeper thought i was really interested in the reason i bring that up with highlights. So so logical momentum takes a very long time to develop. Therefore it takes a long time to unwind and often needs other drivers to help i’m taking the sexual division of labor for example the mind works. Or woman collects at home and drivers of today like convenience foods like reversal of roles, play a part but the shift towards general quality in the work place will take time yeah i mean i think it is a great time and you know what a one level as we see women increasingly coming into. When is senior roles and whether it’s politics of business of the also when are the, when can imagine that this is the result of social awareness and appreciation for the human rights and appropriate good tools like differences between men and women put another level, i think what you’re wanting to is absolutely right which is the society in which you have the traditional unnecessary commitment to cooking on a daily basis, weather in surat lmfao oh whatever it is. The system works against women because women on the truly committed to a tremendous amount of time and the kitchen all equipment is the fact that knowledge is, either we have gotten that is very much easier to do at home because of all the inconvenience is when is the fight club food is often prepared for us are there shops in a way that makes it easy to go, oh that the food is not control because we’re eating out already ordering in the pizza roll over show these very practical aspects that reduce the total amount of time then i women have to spend in preparing food only usually important and freeing women to be a full. To join in the activities of depression me being dominated by men either be dominated by men because mandel been freed by the fact that the women to cook for a blue tome and have lots and lots of time on their hands, play can be the lights in the sciences sound the politicians and business management so i think this is so important to highlight this because, oftentimes people just highlight on furnished yes it is on february built in logic, it’s cold hurry bill to know if fascinated by one of your many interviews for you love that have male and female leadership stars are very different, based on our planned apology and culture yes there was a bomb but the other day talking about the fact that it would probably be a little while doing so would be perfect will be above all the women and challenge i’m with who is the dominant not same as absolute ride in the. A very big difference between men and women is that there is persistence old competition for status and what was te is risk men that remains suspended no way that is truthful revenue women’s certainly can be world leaders and take my own life decisions but, overall things very clear that willingness to take thank is mutated in women in general because according to the way people tend to think about this women’s athletic events to golds conflict is the most important feature is lol not looking to turn when is the clinic where is menu for god to take while risk because if they have huge gains other than the table to translate them into, how much can lead to huge numbers of pics in business a long time, where is for women it makes sense to be able to take leadership positions that keep themselves alive for the sake of the children. When does thanksgiving. Long way down into that understand fundamental psychological differences but we are human is that these kinds of differences wouldn’t someone complaining about the political level as well in general. I think it’s a nigga had that will play out in our society today where there is someone in leadership on netflix, received this version of adam as we see more female leaders committed for example finland, let’s just brought in a whole raft of female leadership receive new zealand and therefore very very different leadership styles and very considered an empathetic leadership styles not driven by ego, but i found a beautiful analogy at all to finish on today. Richard which is in the site almost all hearts by champon these follow a chance encounter during the routine activities, rolling good heart or real boundaries suggesting that companies or on willing to risk spending time on a hopeful search. I thought this was very interesting from and innovation perspective because we have a suggestion to fire this is the origin of this we had more time to explore there for we have more time to leave the caves in which we go out and push the boundaries of society of experimentation and therefore of innovation yes once we learn to control file, everything change a distribution time was a huge part of that if you are a champion z you like to eat meat pause the average duration of is there any twenty minutes i’m the reason that is relatively short is because if a fail then they’re gonna get hungry i’m not able to get enough food then i have to revert to the standard method of eating just got up and the trees and eating fruit. Maybe kind of old the extra time to go and play with things like huntington’s for long periods when we start cooking. And all of a sudden you instead of spending six hours a day eating you’re spending one already did i’ve always available to be able to do all sorts of innovative stuff and that is a huge part of what made human. One last thing you finish the book and i think that’s really important in abundance comes in you scary city and when is the square studies that happens in the world of abundance is so much information out there that there is a scarcity of trust, would equally and this is why i think this book is so important because you’ve gone after science even after real hard day’s to this information to display this information, when are you saying you finish the book and those of us lucky enough to live with plenty the challenge has changed we have to chase energy anymore, but no women’s find ways to make your dependence on coach food even healthier m. das is the new challenge. Yes you know all these years and our evolutionary past we have been and let me just like every other animal just brought to try and solve the problem of anger we have lived to get extra benefits of calorie. Turn all lights change in las few decades we have solved the problem so well new problem is. Get your calories into him about his bm is understanding what cooking does to the foods. We can get new principles for thinking about how to develop why is kind of nutrition and all the sudden. Actually is a good thing you re if you tryin to lose weight so yeah i’m totally on board when. Michael pollan people like him who say that we should try in room without eating though.
