Humans Have a "Natural" Lifespan of 38 Years
Humans have a natural lifespan of around 38 years, according to a new method we have developed for estimating the lifespans of different species by analysing their DNA.Extrapolating from genetic studies of species with known lifespans, we found that the extinct woolly mammoth probably lived around 60 years and bowhead whales can expect to enjoy more than two and a half centuries of life.
