Dr. Tatiana's Sex Advice to All Creation
Evolutionary biologist Olivia Judson takes a humorous survey of animal mating practices in her book Dr. Tatiana's Sex Advice to All Creation, reviewed here at National Geographic. A sidebar presents fun facts from the book. For example, did you know that the fruitfly Drosophila bifurca "is only three millimeters (about one-eighth of an inch) long from the top of its head to the end of its abdomen, yet it produces sperm that are 58 millimeters (2.3 inches) long. If a human male made sperm on a similar scale, they would be as long as a blue whale."
