Seeing how evolutionary mechanisms yield biological diversity
Date:12/22/2009

r 2008) has demonstrated that color vision plays a key role in how cichlids recognize different species and choose mates. (Read more about thiis work here: http://www.newsdesk.umd.edu/scitech/release.cfm?ArticleID=1752)

"Previously, we showed that changes in opsin gene sequence contributed to generating new species," says Carleton. "The speed with which opsin gene expression changes suggests that it might also contribute to creating the incredible diversity of cichlid fishes."

The authors are extending their work to other African Great Lakes and even to coral reef fishes, to better understand how biodiversity is formed.
