Sperm whales live in structured clans similar to early humans, according to new research. Hal Whitehead, the sole author of the study and a professor at Dalhousie University, said the clan systems are matrilineal and average roughly 20,000 females per clan.The discovery will help understand the marine mammals' cultural system and non-vocal behaviour, he said."We often, as biologists, try to make sense of what we see by comparing species.
