Animal DNA Changing with Climate, Study Finds
Longer growing seasons have caused genetic changes in a wide range of animals in the past few decades, biologists announced today.
As the spring reproductive season arrives earlier and lasts longer in northern latitudes, a fact owing to climate change, animals that can adapt their schedules stand a better chance of seeing their genetic information passed on to later generations, leading to a change in gene frequencies within populations.
The shift could have substantial economic impacts as well. As premium growing seasons shift northward, Canada could become an agricultural powerhouse as the United States turns into a dustbowl, the researchers said.

Read about this today in a newspaper. Its amazing that a simplechange of climate can split one ancestor into pretty much similar descendants, although with a great size difference.
