Anchoring helpful genes away from parts of their chromosomes that were more likely to be remixed made tiny saltwater crustaceans better prepared to survive in freshwater ecosystems — like the Great Lakes. New research from Carol Eunmi Lee's UW–Madison lab shows how important genome architecture can be to adaptation to rapid environmental change.

UW researchers turn to the tiny copepod for a big discovery, showing that gene location influences natural selection The new study provides the first empirical evidence connecting the chromosomal location of genes to natural selection and how populations adapt to rapid environmental change.
