"Quintessentially Human" stuff is dwindling all the time. Tools, for example, are used/done by spiders, sea otters, chimpanzees, octopi, and other species with varying degrees of cognitive ability, adaption of the tool, adaption to the tool, etc. etc. The one thing Humans can do that other animals don't, to the same degree, is our complex social groupings used to allow us to exist in a diverse range of ecological niches.
