eh...I'm not impressed. This is simple adaptation. I believe there is a difference in adaptation and evolution (sure, some might argue i'm splitting hairs).
A fish, due to pollution can't see its prey very well, so it adapts to the poor vision the water provides.
In the same vein, its getting cold outside, so my body is beginning to store more fat from the foods i eat for better insulation. Thats not evolution, thats just adaptation.
Show me a fish that is in the process of turning into a completely new species.
Okay, since you clearly don't know what you're talking about (which is about par for this board when it comes to evolution), I'll help you out.
Do you really think the scientists don't know the difference between your body storing more fat and
A SHIFT IN ALLELIC FREQUENCY??
I'll break it down for you: what they're seeing is a shift in the genetic structure of a population. These aren't individual fish improving their eyesight over the span of their lives. These are traits driven by genetic changes over time within the population.
Natural selection occurs in response to a change in environment. Pollution most certainly DOES count in this instance. In any case, whatever the cause, these fish have shown a shift in allelic frequency (uh, by the by, that's the
definition of evolution) within their population that has led to the adaptation of improved eyesight.
When we see enough genetic drift to constitute reproductive isolation, the species will have split into two species. This is evolution at work.
The people who study this sort of thing are just a
little more knowledgable about this than you. Give them the benefit of the doubt on this one, because if you've proven anything with this post it's that you really don't match up to them.
Sorry.
