Donald E Brown, an American anthropologist and scholar, took the time a few decades ago to compile a list of things that all human races appear to have in common. I remember finding this list online a few years ago and pouring over it.
One of the topics that has always interested me is the question of what it means to be human. This list doesn’t answer that question and these things are not uniquely human, but we do appear to share them across disparate cultures. The modern office worker and the Eastern Eurpean cave man’s commonality is documented here, and it’s wonderful.
