«Identifying which of these candidate genes actually causes variation in responses to cold snaps will give us the potential to understand whether evolution to climate change can occur in both wild and domesticated animals, allowing us to better predict which species or breeds will be «winners» and «losers» and to better mitigate the effects of anthropogenic climate change on a wide range of organisms from beneficial pollinators to invasive pests,» said Theodore Morgan an associate professor of evolutionary genetics in the Division of Biology at Kansas State University and senior author of the study.
