Cro-Magnon = early homo sapiens. Although we're apparently the same species, there were a number of anatomical features among them that seem to be rare today, including a slightly larger brain.
Funny fact: the known differences between Cro-Magnon and modern humans are the same as the differences between certain species of wild animals and their domesticated equivalents: larger eyes, neoteny, and so on. It's also possible we're less aggressive than Cro-Magnon, although it wouldn't be possible to test, obviously.
