Email A lizard's penis evolves six times faster than any of its other parts, a new study finds. The study is the first to directly measure the evolution rate of the penis of any species, though researchers have long suspected that the male genitalia evolve faster than other body parts, said study researcher Julia Klaczko, a biologist at the University of Campinas in Brazil. Hemipenes are the pair of organs that make up the version of a penis found in snakes and lizards. But dramatic genital differences are seen among closely related animals with penises, as well. Klaczko and her team chose to measure the genitals of 25 species of Anolis, a group of lizards that live in the Caribbean.

The newly described Humboldt's flying squirrel Glaucomys oregonensis is found in forested habitats along the Pacific coast of North America, from southern British Columbia to southern California. Its range overlaps that of the northern flying squirrel G. When they leap at a target tree, they spread their body into a square a design some BASE jumpers have copied and cover as much feet in a single glide with great accuracy. They use their broad, fluffy tails for steering and braking, slowing down before hitting a target tree.
