Featured guest is bestselling science author, Stanford scientist and atheist Robert Sapolsky,

with a lively discussion of primates, atheism, evolution and

naturalistic explanations for the origin of religions. The show

includes an update on the Foundation's faith-based challenge, going

before the Supreme Court later this month, a song in homage to

stem-cell research, and a look at fascinating freethought writers born

in early February. The show is cohosted by Dan Barker and Annie Laurie

Gaylor, who jointly direct the Freedom From Religion Foundation. (MP3,
