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?

Let's not forget scale orientation. Legless lizard scales are in a circular pattern.

I haven't had a chance to read the article but I'm going to!! And to confuse you all ... I'm a Christian AND I believe in evolution.

An interesting new hypothesis seems to group snakes with certain types of lizard rather than as a sister clade to all the lizards:

Company you share with the original poster's namesake - Mendel was after all a Catholic abbott and scientist who almost certainly believed in evolution.

Good point about my BP.net namesake!

FWI, that site might not be the best place to get info in the future,especially for herp care . Melissa is frowned upon in this hobby by alot of people.

Ok, just a quick tip.

I love the original Mendel, and enjoy the posts of this one as well!!

well, then here's an interesting read....

Interesting thread so far.... But what are these points you're talking about and how do you gain/lose them? Do I have any? How do I know how many someone has?
