There is an amazing evolutionary biology paper out this week in Science:

DNA fragility in the parallel evolution of pelvic reduction in stickleback fish…

Let’s look at what they did.
First, what’s the big picture? Well, numerous species exhibit rapid & repeated bouts of adaptive evolution to new environments. Also, geographically isolated populations of the same species have shown the same phenotypic adaptations (parallel evolution)!
This is the case with stickleback fish, which has lost pelvic fins multiple times as marine populations adapt and colonize freshwater environments. Pelvic fins in marine sticklebacks are thought to deter predators. But in freshwater environments, fin building is too costly
