Baboon Bottom

Caption

Noodle, a female baboon from Kenya, reveals her bright red swollen bottom -- a sign that her time of ovulation is near. Researchers have long thought that baboon males prefer females with bigger backsides as the mark of a good mother, but a new study suggests that the size of a female's swollen rump doesn't matter as much as previously thought.
