Tools predate homo sapiens (which emerged about 300 kYA) by millions of years. The first stone industry - Oldowan - is at least two million years old and might be as old as three million. They predate what we call “archaic humans” by a long time.

Even this evidence of woodworking is largely unremarkable. We’ve got phytolith [1] and microwear [2] studies showing unambiguous evidence of woodworking going back at least 1.5 million years. Wood tools just don’t survive very long, so this find is most notable for its preservation.

This somewhat contradicts the subheading, no?

> The finding, along with the discovery of a 500,000-year-old hammer made of bone, indicates that our human ancestors were making tools even earlier than archaeologists thought.

Well, today I learned something! Thanks for the information, I guess I know which rabbit hole I'm going down today.

The submission's subheading seems to imply that there was a gap where homo* emerged but weren't using tools then though? I can't read the article or copy-paste it due to pay wall, but it says something along the lines of the find suggesting our human ancestors were using tools longer ago than we thought.

I’m going to use a charged word because Jane Goodall used it.

Goodall asserted that humans and chimpanzees (and wolves) are unique among animals in that we have a genocidal tendency [1]. When a group attacks us (or has “land and resources” we want) we don’t just chase them off. We exterminate them. We expend great resources to track them down to ensure they cannot threaten us.

One reading of pre-history is that we had a number of hominids that were fine sharing the world, and humans, who were not. (I’ve seen the uncanny valley hypothesised as a human response to non-human hominids, as well as other humans carrying transmissible disfiguring diseases.)

It’s so cool and strange to think we have examples of tools that literally predate humans.

That's wild! Thanks for sharing. I didn't realize these things went so far back. So are you saying these were straight up non-human primates using tools? Or is this all traceable to our lineage?
