Stumpy = evolution’s triumph


For years, some scientists heralded the end of human evolution. The post-industrial homo sapiens, they argued, was free of the kinds of “survival-of-the-fittest” pressures that could drive large-scale genetic change. Yet new research suggests that humans continue to evolve.

What might our granddaughter’s granddaughter’s granddaughter’s granddaughter’s granddaughter look like? Shorter and stouter, says a report in the Proceedings of the National Academy of Sciences. If current trends continue, its authors predict, then by 2409 descendants of the women in the study will have evolved to be one kilogram heavier and two centimetres shorter than their 2010 foremothers.
