Prepare yourself for an intimate, erotic examination of physical differences between the sexes, from body fat to brain power. See Turkish men demonstrate their suitability as mates by wrestling in olive oil.

Examine brain scans that show that men and women even think differently about the same problems.

'Different But Equal' explores whether the amazing differences between men and women are based on biology or history.
