In Defense of Meat Eaters, Part 1: The Evolutionary Angle

By Mark Sisson
193 Comments

Meat is murder.

Meat will clog your arteries.

Meat is an unnatural food.

Man is really an herbivore.

Meat will give you cancer.

Meat is bad for the environment.

It’s easy to forget that these are the common arguments leveled against meat-eaters. It’s easy to forget that most of the developed world assumes meat is inherently unhealthy – for our health, for the environment, and for animals. It’s easy to forget these things because, as Primal Blueprinters, we’re immersed in the literature and are actively involved in what we eat. To that end we understand that man evolved eating meat, that meat is an important part of a healthy human diet, and that meat production doesn’t have to be the unsustainable, industrialized monster it’s mostly become (and which rightly garners the most negative press). Still, what is the average meat eater to say in opposition to these charges?

First, when people condemn meat-eating, they aren’t actually railing against Primal eaters. They’re fighting a bogeyman, a perverted corruption of what a real meat-eater constitutes. They see the slaughterhouse-porn videos and assume that’s how it always goes down. You mention you eat a high-fat, high-animal food diet, and all they see is E. coli-contaminated blood on your hands. You mention something about local farms and pastured animals, but all they hear is the imagined cries of slaughtered calves, fattened on corn and soy that could have fed starving children. You smell the seared gristle and delicious beefy scent of a grilling steak, while they can smell only the excessive methane flatulence of a cow on a junk food diet. Now I don’t mean to paint an unfair or inaccurate portrait of your average anti-meat activist. But the fact remains that many simply have a viscerally negative reaction to the very idea of meat eating. They see the horrible conditions on factory farms and can think of nothing else. It makes sense, actually; I cringe (and wrinkle my nose) whenever I drive by that CAFO in Coalinga on I-5 heading to northern California, for example. If that’s all they see, I can’t say I blame them for being intolerant of meat-eating.

Still, it’s largely an emotional argument against meat eating, and that can be easily countered with real facts and awareness. By definition, an emotive argument shuns reason (when it conflicts) and clings to straws that bolster the emotion. The passionate anti-meat activist even carries a static arsenal of factoids and soundbites that sound true and gel with Conventional Wisdom. They might sound sensible, but they crumble under close scrutiny. My personal favorites are the anti-meat arguments that invoke human evolution as justification, simply because they’re so specious and so easy to counter. Let’s take a look…

Man is really an herbivore.

They love pulling this one. Fruitarians point to the fruit-loving chimps as proof – they’re our closest living relatives (though not as close as the purely carnivorous Neanderthals were, not that they’d acknowledge that little fact) and they eat a diet of roughly 70% fruit, with some insects and other plant matter thrown in. If they’re our closest living relatives, doesn’t it follow that our diet should be pretty similar to theirs? I dunno about you, but I consider six million years of evolutionary change to be a pretty significant amount of time. Oh, and don’t tell them about those chimps that actively hunt monkeys and other apes for fresh, raw meat. Just show them this video instead.

A lot can happen in six million years. Why, it might even be enough time – theoretically, of course – for a hominid to develop a big brain, hands with a precision grip that facilitated tool development, a fully bipedal gait with proper weight transmission at the ankles, mastery over fire, and a fully-fledged linguistic system. But no, six million years isn’t enough time for hominids to adapt to eating meat.

In reality, of course, meat fueled our evolution, as you’ll see in a bit. We are obligate omnivores, if not closet carnivores (if we have to).

But wait – what about our eight times body length small intestine? Carnivores’ small intestines are around three times their body length, while herbivores have much longer ones, right?

Actually, when measured from ass to mouth (the real distance that matters), our 8 to 1 ratio lies roughly in the middle of the pack between obligate carnivores like dogs (3.5 to 1) and cats (3 to 1), and herbivores like cows (20 to 1) and horses (12 to 1). How perfect is that? The obligate omnivore is nestled right in between the carnivore and the herbivore.

Besides, intestinal length isn’t even the best way to determine dietary need. An animal’s particular arsenal of digestive organs is. Actual herbivores have special organs designated for breaking down cellulose – multi-compartmental stomachs, for example. We have but one, and it absolutely cannot break down cellulose to any significant degree. If we were herbivores, we might even have rabbit-like cecums, highly developed digestive sacs that do the brunt of the digestive work for hindgut digesters. I almost wish we had that capability, if only for the advantage of cecotropes – fecal pellets high in vitamins, nutrients, and proteins that rabbits expel for later consumption. Delicious.

Our measly little stomachs can’t handle all that fiber. If a person really wanted to be a true herbivore, he or she’d have to chew cud for hours (that’s why cows are known for chewing cud – it’s a way to predigest all that tough stuff), vomit it up after a little digestive work in the stomach, and repeat the process. Thanks, but I’ll just take some steak with my salad.

And, like clockwork, they interrupt with:

Okay, maybe we did eat some meat, but we were scavengers fighting over scraps. Meat wasn’t a big part of our diet!

 

Not if you believe the fossil evidence that shows hominids actually manipulated bones “on which flesh was abundant… rather than defleshed from field kills.” We weren’t just starving opportunists. We actively hunted animals, large and small, to obtain large amounts of meat and fat. The only way to get your hands on an intact carcass loaded with delicious flesh – as the evidence clearly shows our ancestors did so on a regular basis – is to kill it yourself. Waiting around for the lions to have their share is hyena territory, scavenger stuff. You don’t become the ultimate predator and propagate your species across the entire globe by solely scavenging for bone scraps – although we did plenty of that, too, as fossil records show evidence of bone marrow extraction from two million years ago using complex stone tools.

If we were meant to eat meat, we’d have claws and big fangs.

Tool-making and large brains are as much an inseparable part of humanity as claws and fangs are of lions. You might argue that claws and fangs “make” the lion, because without them they would die out. Tools and big brains make the man. You can’t take tools away simply because they aren’t a physiological member attached to our bodies; tool making is an integral aspect of human evolution. Our hands and brains make tool usage possible. Think of our tools, our weapons, our hands, and our big brains as our “claws and big fangs.”And as I mentioned earlier, we’ve been using those technological “claws and big fangs” to obtain meat and marrow for at least two million years, plenty of time for tools to become an essential aspect of our human-ness.

Besides, we aren’t arguing that man is purely carnivorous. He certainly can be, but the point of contention is whether meat is a natural part of the human diet. It clearly is. Throwing in shoddy comparisons to actual carnivores like lions and tigers is dishonest and only serves to muddy the waters.

And so, it’s not that we were “meant” to eat meat. It’s simply that we evolved eating meat. Meat represented a reliable source of dense caloric energy packed with nutrients and vitamins essential to our prosperity. Big brains (the existence of which, I’m hoping, even the most ardent vegetarians don’t argue against) were made possible by the consumption of meat, organs, and other nutrient-rich animal products. Instead of spending all their metabolic energy processing cellulose and plant matter, our ancestors turned to a high-meat diet, which utilized fat-soluble vitamins (already converted into the forms we can best take advantage of) and meant energy could be diverted away from a big fermenting pot of a stomach and toward fueling their massive brains. Our brains eat up about 25% of our basal metabolic rate, compared to 8-10% for the apes who eat far less animal matter. Our brains are large and our guts (well, sometimes) are small and bereft of cellulose-consuming bacteria, while a gorilla’s brain is relatively small and its gut enormous and well-equipped with the proper bacteria. How else are they supposed to process all that plant matter?

Easy to digest meat and fat made our big brains possible. I’m not saying vegetarianism makes people stupid, because it doesn’t. I’m just saying they should give credit where credit’s due. You’re able to ruminate on the horrors of meat eating and “articulate” your arguments for a very simple reason: your ancestors ate a ton of fresh, bloody meat and animal fat. Just be glad they didn’t share your dietary proclivities, or else you’d be ruminating on actual grass, twigs, and sticks instead of enjoying culture, language, music, and the other accomplishments of mankind’s big ass brain.

And that about sums up the evolutionary anti-meat angle. It sounds compelling, if all you’ve got under your belt is a semester of high school biology, but it crumbles under real scrutiny.

Tomorrow, we’ll explore a couple other arguments, but for now, let’s discuss any other examples of pseudo-scientific anti-meat talking points grounded in faulty evolutionary science. I’m sure I missed a few…

oops, above post was not meant to be a reply. anyway, about teeth.

I find the best use of my back “herbivore” teeth is for crunching bones and exoskeletons so they dont have anymore sharp edges, as well as grinding up animal skin and gristle into swallowable chunks. funny how the “herbivore adaptation” often cited by veg heads helps to get the most nutrients out of animal parts.

“Tool-making and large brains are as much an inseparable part of humanity as claws and fangs are of lions.”

There seems to be some looping logic here. Many papers say we developed large brains BECAUSE we ate meat. This guy is saying we have large brains to make tools to capture the meat to eat. Which one came first? If we had smaller brains we couldn’t capture meat because we were dumb and couldn’t make tools. We certainly didn’t/don’t have body features to capture any meat like a lion. We can’t rely on any physical attributes to capture meat.

Environmental pressures forced us to search out new food (meat). We did not have the natural tools (claws) for it. We (meaning homo habilis) had to either die, or pick up a sharp rock to slice the meat free and escape scavengers. Many probably did die, but it just required *one* to figure out the sharp rock and get the meat, others just copy behavior. After that brains get rapidly bigger and jaw/gut gets smaller, it’s all about energy dense easy to digest food (meat). It’s not hard, but there is a slight “chicken or egg”.

By definition, an emotive argument shuns reason (when it conflicts) and clings to straws that bolster the emotion.” I don’t disagree with this assessment, but the issue at hand is the question Is killing animals for food wrong or not?

Great post, Mark. Those chimps are intense!

People always point out that apes are herbivores, and that we do not, at first glance, seem carnivorous at all.

In one of your rebuttals to this, you touched on my favorite argument for meat consumption: The human digestive system.

One of the most intriguing arguments is to tell them that the only reason we evolved bigger brains in the first place is because our intestines became smaller with the introduction of meat. You know, Kleiber’s law and all that.

“And so, it’s not that we were ‘meant’ to eat meat. It’s simply that we evolved eating meat.” I think this gets to the crux of the real argument. Most vegans (esp. raw dieters) would say if we weren’t meant to eat meat, then we shouldn’t if other sources are available. Killing animals with tools and cooking them is not the same as killing them with our hands/teeth (or scavanging for them) and eating whole chunks of flesh raw. The extremists would say the best diet tactic is throw out your stove. Blah blah blah. The debate will go on… Read more »

Some of the common ancestors of humans and other primates seem to have evolved to eat meat, and it is speculated that this could have led to bigger brains and longer lives. However, about 2.2 million years ago, our ancestors lost the ability to properly metabolize Neu5Gc, which is very high in red meat. Neu5Gc causes acute inflammation in humans, and we are the only species of primate that does not produce it endogenously. Perhaps this is one of the reasons why the Mediterranean diet seems to work so well. The Mediterranean diet is low in red meat and contains… Read more »

This is just awesome; I love it.

You’re dead-on when you talk about the growing bias against meat-eating, especially in our touchy-feely, divorced from nature society. (I’ve got nothing against being touchy-feely, by the way; just noting that “sensitive” is now often equated with “weak”, and how much we’ve lost touch with the facts of the natural order.) When I tell people I eat meat, I always hold my breath, waiting for the looks of disdain, because of all the times I’ve been judged by ill-informed vegetarians. Isn’t that cracked?

I’m definitely looking forward to the sequels to this post.

Also, are you intimating that one should never argue against a religious position simply because wars have been fought over religion?

But when she made the decision to become a vegan and for boycotting, there was not much option or easy access to responsible animal farming and husbandry as there are now.

What a great coincidence, Mark.

Had been working on this post all morning from an article I was emailed, just posted it and tweeted it, then looked over and saw yours announced on Facebook.

Hope this complements:

“InviQtus, that is because most sophisticated anti meat eaters hold consequentialist views on morality, which make them subject problems like:…” Wyatt, I agree with your list of problems associated with consequentialist views of ethics. My point in mentioning it is only to show that many who are opposed to using animals for food have, if not compelling, at least less embarrassing arguments than the ones shot down in Mark’s blog post. With regard to consequentialism, though, I would say that while your objections should be kept in mind, I am unaware of any ethical theory not open to a similar… Read more »

“Consequentialism seems to me to be the most consonant with the way most thoughtful people tend to decide moral issues and the view most conducive to maintaining healthy, functional societies.” Well, I’d say that smart thieves are the very best at sorting out consequences, rather than operating from moral principles. After all, mere consequences go all ways. If mere consequences are the standard, then, consequences to whom? Thus, the most clever thieves can steal you blind all the while they’re making you believe that it’s to your benefit — that, or they guilt you into buying the “best for society”… Read more »

Since I live in one of America’s most preachy-vegan-infested cities, this information is nice to have presented in a clear and concise manner. Bonus points for including phrase #1 of the top 10 phrases I never expected to see on this website… “ass to mouth.”

Well, I’d like to just bring in a little theological question I have always had. Please don’t be alarmed atheists!! Only certain people believe evolution and christianity cannot co-exist, I am not one of those. It interests me however that we have evolved to eat meat, but haven’t evolved a completely ethical way of doing this. I myself am a huge meat consumer, but spent the majority of my life a vegetarian/vegan/raw vegan. When I was diagnosed with a tummy disorder raw veganism made me sicker and fatter than I have ever been, I took a metabolic test, taking my… Read more »

Jasetyn:

I’ve but a simple and straightforward question: as an American Indian, why would you take up the primitive philosophy (religion) of your conquerors?

Language is one thing, as you have to get along and that’s the only practical means of doing so, but an unnecessary thing like virile, capable American Indians who forged that land and survived on their own for tens of thousands of years bowing to a myth of a crucified Jewish man?

It offends and disappoints even me. Stand up, Woman! For your impressive heritage!

I don’t know about Christianity, but this is how some in Judaism see it:
http://www.chabad.org/library/article_cdo/aid/858870/jewish/Judaism-and-Vegetarianism.htm

I don’t think it is wrong to eat an animal if it is respected and elevated. I believe my body needs meat on a fundamental level, and I would not blame myself for eating it any more than I would blame a tiger for eating meat. The most important thing is to ensure that the animals we eat live happy, free lives and are killed as quickly and painlessly as possible.

I read the Book “Born to Run” and along with stating the obvious benefits of barefoot running and why we run McDougall goes into persistance hunting performed by the Masai tribe in Africa. Then he contradicts that whole thing with saying that a vegan life is what we really should stive for…huh? I believe he got everything right in that book except the vegan part…sad!!!

I’m glad I’m not the only one who picked up on this in the book… I’m reading it at the moment and was thoroughly confused by this. Other than that I think it’s a pretty good book.

Regarding the raw meat argument I like what Don Matesz commented over at Free the Animal:

“Just one point though, if you think it is natural to eat meat, you should eat meat like nature intended you to, raw. Just like EVERY other carnivore and omnivore.”

Nice reasoning (sarcasm). Try this on for size:

Just one point though, if you think it is natural to eat grains and legumes, you should eat grains and legumes like ‘nature intended you to,’ raw. Just like EVERY other gramnivore, e.g. birds.

Joke’s on you. Humans can and do eat raw meat; but can’t eat grains raw.:

I stepped into the world of eating raw meat earlier this week, and I must say it was probably THE best meal I’ve ever had. It fueled my body so perfectly. The meat was incredibly tender, I almost didn’t have to chew. Yes, there are risks, but with enough precaution I think I will continue to eat this way as often as I can. 🙂

I <3 Meat.

InviQtus, I agree with your statement and understand that you merely making observation. Utilitarianism does have an edge with most people because of its rooting in human psychology. That is to say, one can point to experiences like how, “… we are highly social beings and we cannot maintain functional societies without a workable view on how to treat other beings effected by our actions.” A question I have refers to equating usefulness with some transcendent or universal value. My questions extend to all ethical (and anti-ethical) systems. True that Mark took a swipe at popular vegetarianism. Wouldn’t you like… Read more »

“If we were herbivores, we might even have rabbit-like cecums, highly developed digestive sacs that do the brunt of the digestive work for hindgut digesters.” How priceless that so many studies which blame animals fats for heart disease, etc. use rabbits as models! “The Vegetarian Myth” by Lierre Keith is a very good read for anyone who wants to look at the validity of vegetarianism from a political, moral or nutritional standpoint – coming straight from the horse’s mouth, so to speak, since Lierre was a committed vegan for 20 years before realizing it was not the answer for health,… Read more »

that book in your hand is quite possibly the Bible of food! I just discovered it recently, and I have to say that it has changed my life immensely. Of course, I will be getting the Primal Blueprint here soon, because, well…… look what site we’re on. lol.

I experienced first hand that we have to eat meat to thrive. I was a raw foodist for 7 long months and it gave me innumerable problems. The reason why I stuck so long on a diet that was making me weaker is because the dogma is so strong in the raw food community that you are led to believe that everything negative is detox and that you are responsible and the diet is not adjusted well enough on your part. The dogma is dangerous for impressionable young minds looking for an answer and my guess is that a lot… Read more »

“Well, I’d say that smart thieves are the very best at sorting out consequences, rather than operating from moral principles. After all, mere consequences go all ways. If mere consequences are the standard, then, consequences to whom?”-Richard Nikoley By consequentialism I am referring to the moral view that an action is to be judged good or bad on the basis of the consequences of that action as it effects sentient beings. The overriding drive of all sentient beings is toward flourishing and away from suffering. So I would argue that this basic fact about living things is our best frame… Read more »

“Only certain people believe evolution and christianity cannot co-exist, I am not one of those.”-Jasetyn I don’t see how a literal reading of Genesis could be made compatible with the theory of evolution. If Genesis were true we would expect to see all animal species appearing at the same time in the fossil record relatively recently in geological time. That is not what we see at all. So, if you accept evolution by natural selection then you cannot accept a literal reading of the bible. That being the case no one would be able to give you the theological information… Read more »

Literal reading with and understanding of the writer and the language it was translated from.
“In the beginning God created Heaven and Earth” That should be a chapter in itself.
“And now” The beginning of the chain leading to Jesus. Not the beginning of creation. Lucifer had reign over the Earth before Genesis.
The Books of Moses were written about God’s chosen people, not about all people.
Also the word LET…” Let there be light” etc. The original word did not mean create. It meant something similar to “bring back”.

Any interpretation of the Bible that suggests that evolution serves a divine purpose is completely incompatible with evolutionary theory. Evolution is based on *random* mutations and shaped by natural selection. Randomness and purposefulness do not mix.

I cannot believe I wasted so much time as a vegetarian. Now I am zero carb (9 months now) eating just meat and my lifts at the gym have gone up, I have flat abs and tons of energy, clear skin, soft hair, etc. Meat is human food; the rest is for animals. We are meant to get nutrients from animals who eat the nuts, fruits and vegetables. We eat the fatty meat and protein.

Great stuff Mark, seems like some people always trying to rewrite history. I’m 1/2 way through The Primal Blueprint and man do I feel much better with no grains, no potatoes and no sugars, veggies and meat for me. Still working on upgrading the quality of beef I eat. I’m making progress and that’s the key. Fill you in as I go Mark.

Think of the plants! I don’t see why it’s OK to indiscriminately kill plants and not animals. Soybeans don’t want to get eaten either, which is probably why they produce so many antinutrients. Come to think of it, grains (seeds) are the plant equivalent of infants or fetuses – which is probably why they try so hard to reduce our absorption of essential nutrients like calcium and magnesium, eh? How ’bout we just eat nothing; then nothing ever has to die as a result of our evil and selfish desire to eat. Except us, of course. This is all covered… Read more »

God I hate it when meat-eaters give this reply, the “oh, what about the poor suffering plants”. I am a vegetarian, I never try to turn-people vegetarian but when they ask me why I chose this path my first answer is generally “to avoid the suffering of animals, which I feel is unnecessary”, to which people reply “oh but what about the suffering of the poor plants you eat?!”. Plants DO NOT have Central Nervous System; they can not feel pain, they only react to stimuli. It makes me irrationally want to punch people in the face when they reply… Read more »

I got the argument from my vegan father today that cooking meat “stinks” and that’s how we know to stay away from it. Buh?
