Zusammenfassung
The sperm whale, a wide-ranging squid-eater of the deep ocean, has the largest brain on Earth. Female sperm whales form complex societies based upon stable, largely matrilineal units, within which there is communal care for the young. Units share ranges with one another and frequently interact, but seem to maintain distinctive, stable, cultures. Matrilineally-transmitted culture may explain the curiously low mtDNA diversity of the sperm whale and three other whale species with matrilineal social systems. These societies and cultures evolved in a habitat without refuges from predators, with few barriers, cheap movement, and high environmental variability over large scales.
