Snake-like lizards render a fascinating study system to understand how species' phenotypes relate to climate and geographic distribution. Throughout ~180 My of history, elongated and limb reduced forms (snake-like) have evolved in at least 24 times, one of which are precisely the snakes. Along that time, snake-like lizards have evolved in all continents but the Antarctic. In this talk, I show some of my personal experience with them in Brazil and Australia, and how these species’ phenotypes may evolve in relation with climate and geographic distribution
