Changes in precipitation patterns influence natural selection at global scale

What matters more for the evolution of plants and animals, precipitation or temperature? Scientists have found a surprising answer: rain and snow may play a more important role than how hot or cold it is.
Rainfall and snowfall patterns are changing with climate variation, which likely plays a key role in shaping natural selection, according to results published today by an international team of researchers.
Twenty scientists from the United States, Canada, Europe and ... More at https://www.nsf.gov/news/news_summ.jsp?cntn_id=191171&WT.mc_id=USNSF_51&WT.mc_ev=click
