Dr. Juliet Brophy

On the corner of Dr. Juliet Brophy's desk is a skull fossil. "We have Australopithecus africanus, known as Mrs. Ples, that’s my favorite fossil. Everytime I see her I get all dressed up," she says. 

There's an old saying in the South: "A child's gotta eat their share of dirt."

Mamie Lee Hillman's family took this literally, but they weren't after just any old dirt.

"I remember my mom and my aunties eating that white dirt like it was nothing," says Hillman, who grew up in Greene County, Ga., and used to go with her family to dig for their own dirt to snack on. "It was an acceptable thing that people did."
