Mice roar message: genetic change happens fast
Date:10/19/2007

y evolution works in an increasingly human-impacted world," Pergams said.

Lacy studies and compares changes of Volo Bog mice both in the wild and in subsequent generations of their offspring raised in his laboratory.

"It was surprising to us to see how fast genetic and physical change could occur even in the wild population," he said.

Pergams said a lesson of the surprisingly fast replacement of the mouse types is not to assume that animal populations are constant. He also said there's a message for environmentalists.

"Humans are changing the global environment at unprecedented rates," he said. "Plants and animals react to these massive environmental changes either by going extinct or [by] adapting very rapidly."
