Evolution of the Bleached Earless Lizard - EKO Stop 4

Darker lizards are easy for predators to see. While lighter lizards can hide against the gypsum sand, helping them hide. Lizards that escape getting caught due to their white color live longer. If you live longer, you will have more offspring. Their babies will inherit the bright white color and then, in time, pass the coloration onto their own offspring.
You can sometimes see them running around the dunes catching bugs. The lizards talk to each other by bobbing their heads, just like you have probably seen other kinds of lizards do. They do have ears, but they are not visible like ours. The ears have a layer of skin that helps keep the sand out while digging.
