Have chimps entered the Stone Age?

Over 3 million years ago our distant australopithecine ancestors made tools more complex than anything modern day apes can make, the oldest evidence for stone tools dates back 3.4 My old cut marks on ancient animal bones showing signs of having been butchered with stone tools, the next oldest finds are the Lomekwi tool industry, which I’ve gone over before. The Lomekwi tool industry is much more complex than what even chimps can make, but much more primitive than even the Oldowan tools made by early *Homo*. Whoever the makers of the Lomekwi tools were, they deliberately singled out large rocks, at the expense of smaller ones, and their tools are heavier than any stone age tools discovered since then, the largest one weighing 15 kilos.

This is a video by the small and underrated channel North 02 who goes over the common headline that chimps have entered the stone age, he points out that even fish use rocks as tools, and to say that they’ve only recently entered the stone age is ludicrous, we’ve known that chimps have been making tools for at the very least thousands of years (that in and of itself may be due to chimps observing ancient humans making and using stone tools, rather than any innovation among themselves).

I wrote this synopsis of the video both to flesh it out a little bit (specifically the archaeologically focused segment) and provide an explanation of what the video’s about for people uninterested in watching Youtube videos.
