This is making me think about how the Makah on the far northwestern tip of Washington State have no tradition of using the bow and arrow but in the excavations of Ozette village, a Makah settlement that was catastrophically buried in a landslide in the 18th Century, at least one bow and arrow set was found. So apparently for them it's a technology that had been adopted and then later abandoned. I wonder how common that might be over time and geography.
