Vad andra apor innan vår art ätit är hyfsat irrelevant.
Arten
H. sapiens är ca 200ky gammal. Under hela sin existens har kött vart mycket viktigt, undantaget ett fåtal populationer (å andra sidan finns det exempel på populationer som tvärtom nästan
bara äter animalisk föda).
Antagligen var övergången till en proteinrik köttdiet något som gav vår arts utveckling en spark i röven och gjorde oss
snäppet vassare (

) än de andra aporna som till största delen är veggo:

Hej, på samma sida så kan du läsa om vad som verkligen gjorde att vi utvecklade så mycket
"What fueled humans' brain development?
Some have claimed that it was early humans' introduction of meat into their diets that sparked the evolutionary shift that gave us exceptional intelligence. (Too bad that meat-eating didn't provide the same benefit to carnivores like wolves and lions, huh? They're still stuck with those smaller brains.) It's an interesting theory, but besides the fact that it's little more than conjecture and completely unprovable, what's more important is that it couldn't be more irrelevant to the thesis of my article. Even if humans' introduction of small amounts of meat into their diets provided an evolutionary spark, that's completely different from what are bodies are optimized to eat naturally. As I explain above, our anatomy is geared towards eating plant foods almost exclusively, and study after study shows that the more meat we eat, the more disease we suffer from.
The claim also just doesn't make a lot of sense. The primary fuel for our brains is glucose, which is a form of carbohydrate. And meat is completely, 100% devoid of carbohydrate. So we're supposed to believe that the thing that fueled our brain development is a food that our brains can't even use?
In fact, the exact opposite argument has been made: That it was our plant-based diet that was responsible for our evolutionary spark. For example: "Developing a better memory for the exact location of favoured trees, the shortest routes between them and a timetable for when they would likely be fruit-bearing would definitely favour survival." (Grande & Leckie) The T.A. of my nutrition class, after achieving his doctorate, later wrote a book positing that our evolutionary spark was caused by beginining to cook starches, like potatoes, instead of eating them raw. And here's an excerpt from an article about work by University of California researchers:
Man's ability to digest starchy foods like the potato may explain our success on the planet, genetic work suggests. Compared with primates, humans have many more copies of a gene essential for breaking down calorie-rich starches, Nature Genetics reports.
And these extra calories may have been crucial for feeding the larger brains of humans, speculate the University of California Santa Cruz authors.
Previously, experts had wondered if meat in the diet was the answer. However, Dr Nathaniel Dominy and colleagues argue this is improbable.
"Even when you look at modern human hunter-gatherers, meat is a relatively small fraction of their diet. To think that, two to four million years ago, a small-brained, awkwardly bipedal animal could efficiently acquire meat, even by scavenging, just doesn't make a whole lot of sense."
Of course, this is just as much conjecture as the idea that it was meat that made us smart. But the existence of these contrary scholarly opinions serve to show that the idea that meat made us smart isn't widely regarded as fact, not by a long shot"
