A new research that will be published this week in the online edition of Proceedings of the National Academy of Science. The study involves Siberian Hamsters, and their seasonal characteristics, and how their distinct personalities can affect humans.
For instance, these hamsters breed only in the late spring and early summer, when the days are longest. This is for them to prevent giving birth in resource-scarce winter months. The study mainly focuses on decreasing DNA methylation, a methyl group. This will shut down the hamster’s reproductive competency because of the decreased DNA methylation.
