Hi everybody. I'm writing a PhD thesis in Law about right to veganism and, of course, I've studied and considered also biological implications, from our ancestors to the present.
It is impossible even thinking that humans, without tools and fire, were able to eat meat, as well as, before agriculture's invention (about 20.000 years ago), eat plants. They weren't able to cook, nor to seminate, so that they could just eat fruits from plants that didn't imply any killing (neither plants). Of course, they possibly ate little animals and insects, also those contained in fruits (as worms). One thing to be underlined is that today's fruits are not even similar to ancient fruits: today fruits are beautiful, big, seedless, nutritionally poor and that's why today is a little bit harder to be fruitarian.
Anyway we know that humans developed the ability to create, preserve and use fire about 1.4 millions of years ago, but that it was really used just about 4/500.000 years ago. In about the same period they developed the ability to make tools: it was simply impossible, for us, without any tool (arrows, bows, etc.) to hunt. It is also impossible, for us, to eat meat directly from big animals covered with fur, just using teeth and hands, so we needed tools also to slaughter meat before eating. On the other hand we have recent studies about small humans communities living in forrests, as our ancestors did: their eating is about 80% vegan, mainly fruit, and just about 20% small mammals or insects. Last, but not least, until last century, meat eating was rare and, farmers in first place, ate meat about once a week, or less.
