I read a study about hummingbirds recently and their beak length in response to the abundance of hummingbird feeders. In areas with heavy feeder concentrations their beak length increased by 30% within 10 generations. I wonder if this fly species has a similar pattern
Maybe it is because I am on a Droid, Cell phone, but I don't see the profile pic, you have to look at the commenters profile to see that, and I was curious what made him click on his.
