Why snakes dont have legs......(Technical but interesting)

[Mendel's Balls]

Snakes are just lizards without legs and eyelids

The conjunction "and" is key.

I'd also add an "and"

and no external ear openings....

From Melissa Kapplan's page: "Some lizards, including the European legless lizard, California's legless lizard, and the Eastern glass snake (so called because of its defensive tail dropping tendencies) and slender legless lizards, are all lizards who have no legs, living lifestyles that make them unnecessary. They do have external ear openings and moveable eyelids like other lizards. Snakes have neither external ear openings nor moveable eyelids."

So it is a myth that all lizards have legs. (Dan probably knew this).

It be interesting to see the expression patterns of HoxC6 and HoxC8 genes are in legless lizards......it also be interesting to look at the DNA sequence homology of these genes and those of boids.

How legless are legless lizards too? DO these have vestiges of a pelvic griddle and femur?
