I’ve always wondered whether the range and types of “intelligence” expressed by humans and primates vs. other species in the animal kingdom is related to the the difference between those with hands and opposable thumbs and those without.  Being myopically anthropocentric, I never thought about the practical advantages of animal claws.  So of course, the idea of reverse engineering animal claws so that humans could garden more easily didn’t occur to me either. Thanks for this to cousin Ben.
