but we can, you can perfectly fine live on raw meat (pork back fat) nuts etc. And Guts also shrank because they could. It sounds to me like this part mostly came after we learned to cook, then the body didn't need to waste energy on large complex guts. Hugely complicated brains such as Elephants & Whales do just fine on raw food diets.
- Tor3 3y agoErectus are about 2 million years old, and they already had "our" body shape.. i.e. small guts. The question has always been - did they already know how to cook? It's somewhat early for fire control. But it is one of the arguments for the idea that fire/cooking came much earlier than we have physical evidence for. This study/idea about fermented food is exactly about this - if there wasn't fire that early, could it have been fermentation?
- wouldbecouldbe 3y agoSome of it makes sense. The question why & when humans gut could start to shrink. It seems more the other way around in my view, brain development helped develop cooking & other preparation methods and in turn to the need for less complicated guts.
