Climate Change Causing Genetic Change in Animals

Some smaller species of animals, such as squirrels and birds, are changing genetically in order to adapt to rapid climate change, scientists now believe. “Studies show that over the past several decades, rapid climate change has led to heritable, genetic changes in animal populations,” argues Christina Holzapfel, from the University of Oregon in Eugene in a paper in Science published today.

I wonder how long it might take to change the genetic code of some politicians to wake up to the dangers of climate change. Too long, I fear.
