Antechinuses are tiny marsupials famous for their intense sex lives. Now, researchers have documented another unusual behaviour – the cannibalism of their own species.

New findings from the La Brea Tar Pits in southern California suggest human-caused wildfires in the region, along with a warming climate, led to the loss of most of the area’s large mammals.
