UCalgary researchers study how Namibia geckos lost their sticky feet

But... geckos have to have sticky feet, right? I mean, it's by definition. Like flying is part of being a bird, right?

What's that?

Oh. Right. Bad example.

In a study of the evolution of gecko locomotion, University of Calgary biology professor Anthony Russell and his colleagues observed that as geckos from more forested areas to the hyper-arid environs of Namibia, they apparently no longer had much use for the adhesive undersides that would allow their feet to cling to surfaces.

”Geckos have moved out onto these plains where there are no real surfaces to stick to, and have found new ways to get about,” Russell told CBC Radio’s Bob McDonald on Quirks & Quarks.
