Chromatin structure plays a key role in canine social behavior evolution

A new study on dogs found that chromatin's spatial structure has a significant role in the evolution of social behavior. Chromatin, the compact form of DNA, not only packages genetic material but also plays a crucial role in gene regulation. This study demonstrates that both the linear sequence of DNA and its three-dimensional configuration are linked to friendly behavior shaped by dog domestication, providing new insights into the molecular mechanisms underlying social traits.
