Many species are being forced to adapt to slowly rising temperatures around the world. However, some simply do not have the ability to change. They are stuck in a sort of “evolutionary straitjacket.” This includes many species of fruit fly, a common bug found in many houses circling overripe or rotting fruit. According to new research from Monash University, these species may face extinction in the near future, given current projects of a 3 degree C increase in mean annual temperature in the next century and even greater temperature extremes.
