Blind cave fish evolution
Here is an interesting blog entry about a recent paper that discusses the discovery of two related groups of blind cave fish of different species. What's neat is how the split in their lineage happened. I don't want to spoil it by giving away details. Just go read it.

The blogger mentions that she is happy about the research because creationists use the blind cave fish as a mascot. They think a fish losing its eyes gives the theory a metaphorical black eye because, according to their flawed view of evolution, it makes them weaker instead of stronger. Of course, they don't realize that a fish living in complete darkness doesn't need eyes, which means an eyeless fish would be better suited for the environment. Plus, the fact that they can't interbreed means they are not of the same "kind."
