For thousands of years, history has been recorded piecemeal, in books, artifacts, buildings and legends. But in the age of molecular biology, a new archive is helping to fill in the gaps: your genetic code.
Humpback whales can be found all over the world's oceans, despite the heavy beating they took in the era of industrial whaling. They undertake one of the longest annual migrations feeding at high latitudes and breeding near the equator. But there's one peculiar group of humpbacks who live life a bit differently.
