'...A new research paper finds that genetic material from #Neanderthal ancestors may have contributed to the propensity of some people today to be "early risers,"..."
......700,000 years ago, and as a result, our ancestors and archaic #hominins evolved under different environmental conditions. This resulted in the accumulation of lineage-specific genetic variation and phenotypes. When humans came to #Eurasia, they interbred with the archaic hominins on the continent, and this created the potential for humans to gain genetic variants already adapted to these new environments."
