Landmark Paper on 50 Years of Rapid Evolution Published in PNAS
Our groundbreaking study documenting evolution of stickleback over just 50 years on earthquake-uplifted islands has been published in the Proceedings of the National Academy of Sciences!
This landmark paper provides some of the most compelling evidence to date of rapid evolution in nature, showing how threespine stickleback fish have adapted to new freshwater habitats created by the 1964 Alaska earthquake in just five decades.
