shrinking bumblebees!

Global warming and evolution are reshaping the bodies of some American bumblebees, a new study finds.

The tongues of two Rocky Mountains species of bumblebees are about one-quarter shorter than they were 40 years ago, evolving that way because climate change altered the buffet of wildflowers they normally feed from, according to a study published Thursday in the journal Science.

While biologists have tracked how global warming has altered the developmental, migration, timing and other behavior in plants and animals, what makes this study unusual is the physical changes in the bees, said study co-author Candace Galen at the University of Missouri.

“It speaks to the magnitude of the change of the climate that it’s affecting the evolution of the organisms,” Galen said. “It’s a beautiful demonstration of adaptive evolution.”
