Accidental beauty

The difference between the hulking heads of our Neanderthal cousins and our more graceful selves is merely a matter of chance, say scientists in the Journal of Human Evolution. The difference between our skulls and theirs probably results from genetic drift--meaning that our head shape was not selected by nature or in any sense 'intended' but only accidentally came to be. At least we got the nice skulls... the authors of the study say, "Neandertal and modern human crania may simply represent two outcomes from a vast space of random evolutionary possibilities."
