Oh for crying out loud dude. I was going to just leave it alone.
Not a single one of those articles is science at all. They aren't written by scienticists, and the people they are quoting are halfwit anthropologist who are taking guesses, not doing ANY scientific research.
- There is proof change in diet, they discovered fire. But they were still omnivores the whole time. And a vast majority of plants do not give forth useable nutrients to us unless cooked. The one thing that our gigantic brains needed more than anything to function was GLUCOSE. That's it's fuel. When you cook cellulose you get glucose and lots of it. Yes it needs protein and fats, but if you believe that you can't have a big brain on a vegetarian diet, then all children raised in vegetarian households should be brain dead. All the building blocks in the brain (and body for that matter) are found in plants. And if you look at predominately vegetarian primates, their long intestines are way longer than ours because they can't cook cellulose. ( There should have been evolutionary pressure not to eat meat. Vegans and vegetarians don't get strokes and heart attacks nearly as often, and we live 4 years longer on average
)
- if you so fervently believe in evolution, and claim I do not, perhaps take a look at a entirely more believable evolutionary reasoning for such big brain- THE ONE THAT IS EXCEPTED AS SCIENCE THE WHOLE WORLD OVER.At the time there were about a dozen hominid species running around and clubbing everything that moved and pillaging. The dumb ones that couldn't make tools were killed off. Then the ones that didn't make fire were killed off. But the biggest evolutionary win was language. Our brains (specifically the prefrontal cortex) are designed for high level interactions with other creatures. Now we believe that about 4-5 hominid species has the ability to speak languages. They created cities and burried their dead in religious fashion.
The brain game ramped up speed and evolution chose the winner. Whoever was the smartest most efficient won. (Intelligence also has nothing to do with brain sizes, see elephants, or even female vs male human brains)
Obviously, we won by running around raping and killing everything that walked on two legs as you can see Neanderthal DNA in our genome. We were the best at language, tool making, infrastructure etc. There IS scientific evidence of that whole situation happening unlike the mere conjecture that big brains require meat.
- oh ffs seriously with the plants? Now reaction to stimiuli is having a brain? Give me a break. Again- that article is not science. Any botanist worth their salt will never ever say that plants have brains or could ever become anywhere near sentient.
And again its just assuming glutamate channels=brain. Sea sponges are our genetic ancestor. They gave us our Cannabinoid receptors. But they use it to regulate their homeostasis.
We use it to help reduce cortisol levels when dealing with annoying pseudoscience.
If you want me to source anything I will. I just don't have the time to produce the hundreds of evolutionary biology/psychology and neuroscience journals that I just used.
And to wrap up. You live in an industrialized economy with a hyper abundance of food. There is no genetic, evolutionary, dietary reason to eat meat anymore. I grant that indigenous people still need their goats and chickens to survive but you most certainly do not.
Perhaps humans will all evolve someday to realize that killing does not have to be a part of life for us anymore. Human discovered the higgs boson, we are certainly smart enough to come up with sane, ethical ways to deal with silly invasive possums -_-
