Lizards rapidly evolve after introduction to an island
http://news.nationalgeographic.com/n...evolution.html
Italian wall lizards introduced to a tiny island off the coast of Croatia are evolving in ways that would normally take millions of years to play out, new research shows.
In just a few decades the 5-inch-long (13-centimeter-long) lizards have developed a completely new gut structure, larger heads, and a harder bite, researchers say.

In 1971, scientists transplanted five adult pairs of the reptiles from their original island home in Pod Kopiste to the tiny neighboring island of Pod Mrcaru, both in the south Adriatic Sea.
Genetic testing on the Pod Mrcaru lizards confirmed that the modern population of more than 5,000 Italian wall lizards are all descendants of the original ten lizards left

Those buggers are a load of fun. In southern Italy, where I'm from, they're everywhere. I used to catch them as a kid.

"The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him." Leo Tolstoy, 1897

Sounds like the info to trigger the changes were already there, coded in their DNA.

I hate genetics. It's so hard to understand. Plus, it doesn't make sense. Why would God make something that's so complicated? Why aren't we just solid bodies of flesh with a head so we can see and hear, legs to move, and arms to do stuff with?

Could be, also could be the changes are developmental, not genetic. In other words their diet is affecting the way their gut and head develops, while their genes are still the same as the parental line. I wonder if they've found a genetic basis for the changes yet? An easy test would be to take some before they hatch and put them back on the original island and see if they look like their parents or like their ancestors on the original island. Or maybe you'd have to have the parents on the original island before they conceive, eating the old diet. Pretty cool stuff either way.

No what's it about?
Another thought, a person lives in JApan and eats a fish and rice diet, they move to America and the kids start eating big mac's and become fat, evolution at work? Or a response to eviroment?
