Lizards' camouflage reveals evolution

Two species of lizard that have developed white scales for camouflage are giving scientists a chance to see evolution in action.
This change in color for the traditionally brown lizards provides a rare chance for scientists to observe evolution as it happens, illuminating both the mechanics of adaptation and speciation.
In White Sands, N.M., two species of traditionally brown lizards have evolved white scales in order to blend in with their environment. By studying the genetic mechanisms at work in this adaptation, scientists are able to observe evolution as it happens. The study illuminates the mechanics of not only adaptation, but also speciation, or how species form.

Prepare for the hordes of Young Earth Creationists 'debunking' this... Oh don't you worry. A change in color or size has no connection to the kind of evolution that Darwinists want people to believe. There is no mutational advance whereby new structures are forming changing the one organism to another. There is no evidence for the common ancestry of all living things. Evolutionist tend to utilize the "bait-switch fallacy" when trying to promote one type of evolution publicly by creating press releases about micro-evolution whereby color and size changes are observed; all the while, wanting the...

And yet again I would like to point out that Evolution is Biology... which has no correlation to the debate over how things "began" Though to add something on topic. You can bet if the color change makes it more likely for these lizards to live longer lives. That will also result in them being more likely to produce offspring. And thus more likely to pass their genes on to future members of their kind. Resulting in a higher percentage of lizards having this color change. Rinse, repeat........ evolution. Despite the fact that people like to tell you it's more complex than that. It's very simple... [More]

There is no evidence for the common ancestry of all living things. Despite the fact that you are wrong, it is nice to see a creationist who knows about common ancestry rather than spouting all that rubbish about crocaduck and badgers giving birth to gerbils.
