Rodent's evolution a genetic puzzle

Purdue University researcher J. Andrew DeWoody calls voles an "evolutionary enigma" with many bizarre traits. Studying traits of the small rodents, which evolve 60-100 times faster than the average vertebrate, could lead to a better understanding of human genetics and genetic disorders. |
A small, mouse-like rodent has the potential to shed light on human genetics and the mysteries of evolution.
Purdue Agriculture research shows that the vole is not only the fastest evolving mammal, but also harbors a number of puzzling genetic traits that challenge current scientific understanding.
"Nobody has posters of voles on their wall," says J. Andrew DeWoody, associate professor of genetics in the Department of Forestry and Natural Resources. "But when it comes down to it, voles deserve more attention."
Often considered agricultural pests because they eat vegetation, voles are an "evolutionary enigma" with many bizarre traits. "The vole is a great model system to study natural phenomena that could impact humans," DeWoody says. Understanding some of the voles' more unusual traits, like their vast genetic variation yet indistinguishable appearance, would lead to greater knowledge of human genetics and genetic disorders and could have important implications for gene therapy.
