How long were humans meant to live?
Using the human genome, the researchers found that the maximum natural lifespan of humans is 38 years, which matches anthropological estimates of lifespan in early modern humans. They found Neanderthals and Denisovans had a maximum lifespan of 37.8 years, similar to modern humans living around the same time.
