If you imagine Tina Turner in thunder dome combined with Carl Sagan, you get Nina Jablonski. She is the head of the anthropology department at Penn state. In her stylish attire and commanding persona she taught a primatology class I took last semester. Every time I went to class I felt like I was watching a episode of Cosmos. She told us all about her field work studying Tarsiers in Borneo and how wondrous evolution is. Professor Jablonski has also found the oldest chimpanzee fossil yet discovered. When she is not studying are distant relatives, she studies human skin pigmentation. She wrote a book called Skin: A Natural History and has been a guest at Ted Talks and the Colbert Report discussing the book.
