New Darwin video: A Ghost of Evolution

I have just posted a video on my YouTube channel in which Charles Darwin explains an example of coevolution. Mammals and fruits have coevolved, but the mammal disperser of bois-d'arc seeds has become extinct. To understand the ecology of fruit dispersal you must understand evolutionary history: the extinct mammal is a "ghost of evolution."
