The emergence of asymmetrical flatfishes, such as halibut, flounder, and sole, has long been an evolutionary puzzle. Their truly strange asymmetrical heads are one of the most unusual body features among vertebrates, the evolution of which has been hard to explain. How did an animal evolve to feature both their eyes on one side of [...]

Flatfish have been a fishy problem for evolution for a while. All living flatfish (halibut, flounder, sole) have both eyes on one side of their head. Some have them on the right, others on the left. The odd part is...... Read Post
This talk should put me back in my comfort zone—developmental biology, evolution, and fish, with the stickleback story, one of the really cool model systems that have emerged to study those subjects. Read the comments on this post..... Read Post
Those delicious flatfishes, like halibut and sole, are also evolutionary puzzles. Their profoundly asymmetrical heads have one of the most unusual body plans among all backboned animals (vertebrates) but the evolution of their bizar... Read Post
