Urban lizards evolved stickier feet for city living

Millennials aren’t the only ones adapting to live in cities—one species of urban lizard has evolved stickier feet and longer legs to better cling to surfaces like metal and glass, New Scientist reports. Scientists compared male anole lizards living in three cities in Puerto Rico with those living in nearby forests, and found that they had longer limbs and more of the scaly structures that allow them to stick to surfaces, according to a study in the journal Evolution. The lizards, which have been observed to evolve rapidly in the wild, appear to have evolved to cling to and walk on often slippery urban surfaces.
