IT'S STILL A MOUSE

Speedy Evolution Detected in Windy City's Wild Mice (Scientific American, 05/22/2003)

The white-footed mouse isn't much to look at, but a new study suggests it may be a superstar when it comes to evolution. According to a report published today in the journal Nature, a group of the animals in the Chicago area has undergone significant genetic change over the last 150 years. The findings suggest that a mammalian genome can evolve much more rapidly than previously thought.

One might think the headline would cite genetic change instead of evolution, since it isn't clear that the mouse has "evolved" at all. Posted by Stephen Judd at May 27, 2003 3:46 PM
