Has it been shown to be true that chimpanzees can learn to make and use a fire to cook?
Not that I have ever heard of. I know they use "tools" to eat. They will use a piece of bark like a spoon. Or a blade of grass to lure bugs out of a nest.
I doubt it
Show me where a chimp can make fire- That's impossible for a chimpso the answer is - heck no !
Hey they have gone to space before man did but they don't have much need for cooking unless they are cooking for us:
I can't wait to see the recipe book.
