A series of unfortunate evolutionary events: marine mammals lose pesticide protection

As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that defends humans and other land-dwelling mammals from the neurotoxic effects of a popular human-made pesticide. The implications of this discovery led researchers to call for monitoring our waterways to learn more about the impact of pesticides and agricultural run-off on marine mammals, such as dolphins, manatees, seals and whales.

A series of unfortunate evolutionary events: marine mammals lose pesticide protection

Genetic research shows seals, whales and dugongs all at risk, due to separate but similar evolutionary pressures. Stephen Fleischfresser reports.
