Dark-Dwelling Fish Converge On Blindness
Lisa came across an attention-grabbing story posted on Scientific American. Here’s a taste:
When Mexican tetra fish moved into dark caves long ago, they evolved to deal with the dark by becoming albino…and going blind. And new research shows that the changes various cavefish populations went through occurred repeatedly–a massive, textbook example of convergent evolution. The study is in the journal BioMed Central Evolutionary Biology . [Martina Bradic et al, Gene flow and population structure in the Mexican blind cavefish complex (Astyanax mexicanus )]
