Researchers from the University of Cambridge in the United Kingdom and the University of Tübingen in Germany set out to investigate how the average body size of humans has changed, and how this could be linked to temperature. Their findings, published in the journal Nature Communications, are enlightening, to say the least.

Researchers examine how climate has affected body size during evolution

  TORONTO A group of researchers have found the connection between climate and humans’ fluctuating body size as we’ve evolved over the last million years. The study, published in Nature Communications on Thursday, found that human size fluctuated significantly over the last million years, and that colder temperatures meant larger body sizes. It also found that brain size has changed dramatically but not in conjunction with body size changes or temperatures. The team from Cambridge University and the University of Tübingen looked at the 300 fossils of the genus Homo from across the globe and regional climates from the last million years. They combined this data to pinpoint the exact climate each fossil would have lived through.
