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.

Les changements de température modifient la taille du corps humain

Sciences Repéré par Emma Barrier En revanche, la taille du cerveau n a rien à voir avec le climat. Les Homo Sapiens sont 50% plus lourds que les Homo Habilis. | Johannes Plenio via Unsplash Temps de lecture: 2 min Repéré sur CNN Au cours des derniers millions d années, la taille moyenne des corps humains a significativement évolué et d après une étude, il s agit d un effet du changement climatique, rapporte CNN. Une équipe de scientifiques dirigée par l université de Cambridge et celle de Tübingen a rassemblé des données concernant la taille de cerveaux et de corps de plus de 300 fossiles de la famille Homo, à laquelle les humains modernes, Homo Sapiens, appartiennent.

Climate change altered the size of human bodies

Climate change altered the size of human bodies By Amy Woodyatt, CNN enablePagination: false endIndex: (CNN) The average body size of humans has fluctuated significantly over the last million years and is linked to a changing climate, according to research published Thursday. A team of researchers led by the University of Cambridge in the United Kingdom and the University of Tübingen in Germany gathered measurements of brain and body size for more than 300 fossils from the Homo genus or family, to which modern day humans Homo sapiens belong. The team used this data, combined with a reconstruction of the Earth s regional climates from the last million years, and calculated the climate that would have been experienced by each fossil when it was a living human.
