Sex and the Single Sloth: A Darwinian Valentine

The Museum of Natural and Cultural History invites you to the first in its 2014 series of Darwin Days Lectures. Join Greg McDonald, the National Park Service’s Senior Curator of Natural History, for an intimate look at extinct giant ground sloths – including their ecology, evolution, and how to tell the “boys” from the “girls.” From fossils discovered by Darwin in South America to remains later unearthed in Oregon, Dr. McDonald will discuss recent research on giant sloths and the light it sheds on the natural history of these fascinating mammals.  The lecture is free and open to the public.
