Evolution at work? Craziest thing I've seen all day.

Its clearly evolution. Did you read the part about the calcium and how it is completely different between the egg laying southerners and the live birth northerners? Clearly they are adapting to the environment for the well being of the species. They have changed their bodily functions to have the beginnigns of a placenta and nutrient flow vs just egg laying.

No, I didn't see anything that suggested such a difference within this species. Can you show it, quote it?

It states that in egg laying animals the embroyo gets calcium nutrients from the egg itself, however since this lizard has not eggs but a very thin membrane it would be lacking the calcium and would have defects. In mammals, the uterus and subsequent placenta actaully connects the mom/child to provide this, as well as all other, nutrients. The northern lizards have begun this process by delivering the first nutrient required, i.e. calcium due to lack of thick shell. This is evolution of a placenta (similar to you mom's) where the mom/child are linked and all nutrients flow through.
