A team of researchers from several institutions in the U.K. and one in the U.S. has found that human culture evolves just as slowly as biological evolution. In their paper published in the journal Nature Human Behavior, the group describes how they developed metrics for cultural evolution and compared them with metrics for biological evolution....
