A new study looks at genomic changes through human evolution and finds, for the most part, evolution has improved the genetic foundations for human health in the most part. However, modern humans appear to be at more of a genetic predisposition to mental health problems than our ancestors.
A new study in Scientific Reports finds evidence from MRI scans suggests Neanderthal derived genetic variations affect how the brains of modern humans work. Findings may shed light on specific deficits seen in ASD and schizophrenia, researchers believe.
Researchers report modern humans who carry particular Neanderthal DNA fragments have slightly less rounded heads. The findings shed light on the evolution of modern brain shape and function.
