Here we explore an example (that of Steller's sea cow, Hydrodamalis gigas) that can help inform this hypothesis for Pleistocene extinctions.This particular case is intriguing and potentially informative because various aspects of the rise and fall of sea cows are reasonably well known; the final step in the sea cows' demise occurred just several hundred years ago, in the presence of modern .
