Flatfish Evolution

Ever heard of the 'Picasso Fish'; Which has both its eyes on either side of its head? Well, scientists are now working on figuring out how it evolved. Some had suggested that perhaps genes which control development had switched one eye to the other side of the head in one fell swoop; Yet a recently examined fossil suggests that it evolved gradually. Check out the new transitional fish fossil at Carl Zimmer's blog, or see the peer-reviewed article.
