Crucial questions are raised, such as “Why do mens’ testicles have such a bad location?” and “Who does God like better, us—or squid? Once she mentions testicles, everybody pays attention.

She has written a book titled The Not-So-Intelligent Designer—Why Evolution Explains the Human Body and Intelligent Design Does Not which was published in 2015.

Dr. Hafer has a doctorate in zoology from Oxford University, and teaches human anatomy and physiology at Curry College. She is a former DJ and loves doing radio and TV.
