Joseph L. Graves, Jr., is an evolutionary biologist at North Carolina A&T State University. He's the author of The Emperor's New Clothes: Biological Theories of Race at the Millennium.

“We want our children and grandchildren to live in a world that isn't depleted-a world with clean water, air, abundant plant and wildlife, and energy-a world we would be proud to pass on.”

Evolutionary biologists study the origin and descent of species, as well as how they change over time. One of Dr. Graves' areas of study is the biological concept of race in humans.
