"Denisovan DNA: Ancient Ancestry Linked to Modern Mental Health Disorders"

Modern humans interbred with Denisovans, an extinct human species, which resulted in a genetic adaptation for zinc regulation that helped humans adapt to cold climates. However, this adaptation may also predispose individuals to mental health disorders such as depression and schizophrenia. The genetic variant observed, which affects zinc regulation, is widespread in non-African populations and is associated with a greater predisposition to psychiatric diseases. The variant is believed to have originated from interbreeding with Denisovans and has left a global mark, except in African populations. Further research is needed to understand the full implications of this genetic adaptation on mental health.
