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? [1] https://www.nature.com/articles/nature16990 https://www.nature.com/articles/nature16990
