Are you a morning person? That may just be your 'Neanderthal Genes' manifesting

Neanderthals, ancient hominins who disappeared from the fossil record around 40,000 years ago, were found to have shared genetic variants related to sleep with modern humans. A recent study compared the DNA of living humans with genetic material retrieved from Neanderthal fossils. The research revealed that Neanderthals carried clock-related genetic variants similar to those found in individuals who identify as early risers. The study also suggested that mutations in certain body-clock genes unique to Neanderthals might have influenced their circadian rhythms. This finding offers insights into how ancient hominins adapted to different environments.
