Episode 221 - Legless Lizards
Lizards are extremely good at becoming snake-shaped. A long body with small or absent limbs is a shape that has evolved dozens of times across nearly every major lineage of lizards. This episode, we explore the diversity of leglessness in lizards, we discuss which groups have done it and which groups have done it best, and we examine what’s known about the repeated evolution of this unexpected body shape.
In the news: giant dusky salamander, very early footprints, a Denisovan skull, a mammoth tusk boomerang, and night lizards.
