"The Enduring Impact of an Ice Age Discovery on Humanity"

Researchers have linked a gene inherited from ancient Denisovans to neurological disorders in modern humans, suggesting that it may have helped ancient humans adapt to colder climates. The gene variant SLC30A9, responsible for controlling zinc transportation across cell membranes, has been found to be associated with conditions such as depression, hyperactivity disorder, autism spectrum disorder, and schizophrenia. This gene variant, believed to have originated from interbreeding with Denisovans, has spread to majority of modern populations outside Africa, impacting their susceptibility to neuropsychiatric disorders. The discovery offers insight into the influence of Denisovan DNA on modern humans and sheds light on the genetic adaptations to different environments.
