Scientists Pinpoint Single Gene Responsible for Initiating Winter Behavior of Mammals

Single gene responsible for hibernation in mammals, study finds

The gene is present in all mammals and the study reveals the intrinsic mechanism behind hibernation and migration. Scientists have made a significant step in understanding the genetic mechanism behind seasonal behaviours in mammals, such as hibernation and migration. A study led by the University of Glasgow pinpoints a single gene, called Dio3, as being behind these behaviours. This gene is present in all mammals and the study reveals the intrin…

As the days continue to get shorter, scientists have made a significant discovery in understanding exactly what makes mammals exhibit seasonal behaviors like hibernation and migration.

Scientists pinpoint single gene responsible for initiating winter behaviour of mammals

17.11.2025 - As the days continue to get shorter scientists have made a significant step in understanding exactly what makes mammals exhibit seasonal behaviours like hibernation and migration. The study - published in the journal eLife and led by the University of Glasgow - pinpoints a single gene, the Dio3 gene, present across all mammals, as the biological mechanism behind seasonal behaviours.
