Something I find incredibly cool is that they’ve found neandertal bone tools made from polished rib bones, and they couldn’t figure out what they were for for the life of them. 

Until, of course, they showed it to a traditional leatherworker and she took one look at it and said “Oh yeah sure that’s a leather burnisher, you use it to close the pores of leather and work oil into the hide to make it waterproof. Mine looks just the same.” 

“Wait you’re still using the exact same fucking thing 50,000 years later???”

“Well, yeah. We’ve tried other things. Metal scratches up and damages the hide. Wood splinters and wears out. Bone lasts forever and gives the best polish. There are new, cheaper plastic ones, but they crack and break after a couple years. A bone polisher is nearly indestructible, and only gets better with age. The more you use a bone polisher the better it works.”

It’s just. 

50,000 years. 50,000. And over that huge arc of time, we’ve been quietly using the exact same thing, unchanged, because we simply haven’t found anything better to do the job. 

This story is also excellently cool because it’s yet another example of how everybody benefits when specialists from different fields communicate with one another.
