Study: Genetic Variant Inherited from Neanderthals Reduces Activity of Key Muscle Enzyme
Velazquez-Arcelay et al. found that genetic material from Neanderthal ancestors may have contributed to the propensity of some people today to be early risers, the sort of people who are more comfortable getting up and going to bed earlier. Image credit: Holger Neumann / Neanderthal Museum.

The Neanderthal variant in AMPD1 decreases its enzymatic activity by 25% in lab-produced proteins and by up to 80% in the muscles of genetically engineered mice.
