Thank you for your answer. Found a similar explanation in[1].
But my question is not really about: should humans eating meat? I know we eat meat(in general). I know it made us who we are, and we are all gonna die.
My question is rather. It is a question people ask, and the answer from our modernday oracles is honestly bullshit.
So who to ask? Yes Google Scholar used to pop up. It does not any more. I/we have to know.
And honestly again I no longer really trust any of Googles/abc's products.
So let me try to rephrase.
Where would normal people like my self seek information, without knowing the correct lingo in advance?
