#bipedalism — Public Fediverse posts

Why do humans exhibit such a striking right-hand preference? This study of 41 anthropoid species reveals #Homosapiens as an evolutionary outlier & identifies #bipedalism & #brain expansion as likely drivers of human lateralization @PLOSBiology https://plos.io/4ufOvWJ

Did our ancestors walk upright earlier than we thought? New analysis shows Sahelanthropus tchadensis was bipedal 7 million years ago, pushing the origins of human walking to the dawn of our lineage. #Archaeology #Anthropology #HumanEvolution #Bipedalism #Fossils https://www.anthropology.net/p/standing-up-in-the-sahel

Uncovering the #Genes That Let Our Ancestors Walk Upright
A new study reveals some of the crucial molecular steps on the path to #bipedalism.
“Man alone has become a biped,” Darwin wrote. Bipedalism, he declared, was one of humanity’s “most conspicuous characters.”
Scientists have now discovered some of the crucial molecular steps. Some genes became active in novel places in the human embryo, while others turned on and off at different times.

New research shows the human pelvis didn’t evolve gradually—it flipped its growth pattern 90° and rewired bone formation. These shifts let our ancestors walk upright and birth big-brained babies. #HumanEvolution #Anthropology #Bipedalism https://www.anthropology.net/p/two-genetic-leaps-that-set-us-walking

Did we evolve from a knuckle walking ape? Probably not.
What evidence we have so far points to something else.
