Genomic evidence of rapid adaptation of invasive Burmese pythons in Florida  

New researchers set out to determine whether pythons could have adapted to an extreme Florida freeze event in 2010. They generated data for dozens of samples before and after the freeze event. By scanning regions of the Burmese python genome, they identified parts of the genome that changed significantly between the two time periods, providing clear evidence of evolution occurring over a very short time scale in this population.
