Reply to comment by sabrtoothlion in Chernobyl black frogs reveal evolution in action by Picture-unrelated

There's a selective pressure for darker skinned frogs. This pressure means that the darker skins frogs are more likely to produce young. Over generations, this effect is compounded. Eventually, the dark frogs will far outnumber the lighter.

Think of it this way; a tan is adaptation. The ability to tan, coming about as a result of generations of sun exposure and resulting cancers, is evolution.

Evolution writ large requires the production of new genetic information in the living population. This is simply natural selection of traits that already existed in the population, not the complete cycle. Unless I'm reading the article wrong.
