Rapid evolution may help species adapt to climate change and competition

A study shows that a fruit fly species can adapt rapidly to an invader and this evolutionary change can affect how they deal with a stressful climate. Over a few months, the naturalized species adapted to the invasive species' presence. This affected how the flies adapted to cold weather. The flies exposed to invasive species evolved in the fall to be larger, lay fewer eggs and develop faster than flies that hadn't been exposed.
