Deep-diving, squid-eating *sperm whales are found in every ocean, where they can mate with partners from around the world; as such, they should be quite genetically diverse. Yet, their genetic diversity is actually very low, hinting that something killed a lot of them off in the past.

   To reach this conclusion, researchers analyzed the DNA from 175 sperm whale samples collected from live and dead stranded whales across the globe. Their analysis showed that the current global distribution of sperm whales resulted from a population expansion starting about 100,000 years ago. Sperm whales at that time had apparently been reduced to a small population of about 10,000, when a freezing world during the glacial period caused extensive ice to exclude them from all oceans except the Pacific.

Today's sperm whales (about 360,000 animals) are all descended from this single population, the team reports online in Molecular Ecology. They have subsequently *colonized other oceans, the scientists say.
