Sexy stickleback

For biology nerds and J.T. fans:



That's right, it's a song about stickleback to the tune of "Sexy Back". UC Berkeley seems like a fun place.



PS In case you weren't aware, here is what a stickleback looks like. Sticklebacks are great organisms for the study of evolution because they have evolved different morphology (and behavior!) depending on their environment. For example, ocean stickleback are different than lake and river stickleback. Even in the same lake you can find two different forms of stickleback in the deep and shallow parts of the lake. By making hybrids and looking at their DNA, scientists have found genes that control different parts of stickleback development and morphology.
