Three continents of fruit flies mark climate change

The European fruit fly is experiencing genetic changes due to a fast-warming climate, scientists warn. Now the changes are apparent on three different continents since the fruit fly’s accidental introduction to North and South America about 25 years ago.

"This is a clear signal on three different continents that climate change is occurring, and that genetic change is going along with it," said Raymond Huey, a University of Washington biology professor who is co-author of a paper describing the findings.
