Populations of fruit flies on three separate continents have independently evolved identical gene changes within just two decades, apparently to cope with global warming.

how do they know that it is done independently. All it would take is a few to get carried by plane or cargo to a new area, then interbreed with those in that area. Unless im misreading it, they dont know if they evolved or migrated.
Oh boy!!! An evolutionary/global warming double whammy!
This'll have the conspiracy theorists in a frenzy.
Nice one DA.
PS should that say 'testify' or 'tsetse fly'
lol sorry couldn't resist that one.
dehammer I'd try to help you with this one but it would just go sideways and I'd be shaking my head. So if you are truly interested study genetics and learn how it is that geneticists can tell the difference.
I'll give you one hint:
