Our #evolutionary path to #bipedalism is best described as a cross between 'hold my beer' & 'there I fixed it.' Our knees are a polite suggestion, our backs are a sternly-worded letter, & the only things we have going for us are our brains, social nature, & the fact we made stamina our dump stat. 🧪

When Did Bipedal Walking Begin? NEW YORK, NEW YORK—A new study of seven-million-year-old Sahelanthropus tchadensis fossils employing 3D imagery suggests […] The post When Did Bipedal Walking Begin? appeared first on Archaeology Magazine.

I see Mozambique’s baboons as windows into hominid evolution In Gorongosa National Park in Mozambique, Rassina Farassi studies how humans came to walk on two legs.

Standing Up in the Sahel New fossils suggest upright walking began earlier than we thought

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 www.anthropology.net/p/standing-u...

#bipedalism

On #ThisDayInHistory in 1974, #Lucy was discovered in Hadar, #Ethiopia, and named for the Beatles song. Lucy is 40% of an #AustralopithecusAfarensis skeleton, and verified that #bipedalism preceded expansion of the hominin brain. Creationist nuts still can't deal with basic fact.

There should!

Though m/f pelvises likely co-evolved in some fashion, the female structure is arguably more advanced 😃

Human Hip Evolution: Rotation and Delayed Ossification Drive Walking

Human pelvis development involves a 90° rotation of the iliac growth plate by day 53 and a 16‑week delay in bone hardening, creating a short, wide shape for upright walking. getnews.me/human-hip-evolution-rota... #human #pelvis #bipedalism

Two Steps to Bipedalism Why did the early hominin take two steps to become bipedal? Because they read the Nature article!

The evolution of hominin bipedalism in two steps - Nature The human pelvis exhibits distinct spatiotemporal ossification patterns and an ilium cartilage growth plate that is shifted perpendicularly compared with those of other mammals and non-human primates—two key adaptations that underlie bipedalism.

Two Genetic Leaps That Set Us Walking New research traces the pelvic transformation that let humans rise from the trees

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

Walking on Two Legs May Have Evolved in Trees, Not on the Ground New research on chimpanzees living in the open woodlands of Tanzania suggests that the story of how humans learned to walk on two legs may need a rewrite. Despite their dry, savannah-mosaic environment,...

Canopy survival in the savanna? New research from Issa Valley chimpanzees challenges assumptions about early bipedalism, suggesting upright walking evolved in the trees, not just on the ground. #Anthropology #Primatology #HumanEvolution #Bipedalism

New study on Issa Valley chimpanzees shows bipedalism may have evolved in trees, not just on the ground. Foraging needs in open woodlands kept apes climbing. Rethinking human origins? 🐒🌳 #HumanEvolution #Primatology #Anthropology #Archaeology #Bipedalism

🌍 Recent studies suggest savanna-dwelling chimpanzees offer insights into early human bipedalism, highlighting their adaptation to both climbing and walking as forests evolved into savanna. Link: https://tinyurl.com/245krfr5 #HumanEvolution #Bipedalism #ClimateChange 🌿

Australopithecus afarensis could walk well but lacked efficient running traits. Short legs & no Achilles tendon limited speed, marking Homo erectus as a turning point in running evolution. #Evolution #Anthropology #Paleontology #HumanEvolution #Hominin #Bipedalism #Australopithecus #Lucy

Humans evolved for distance running – but ancestor ‘Lucy’ didn’t go far or fast 3D models of Australopithecus afarensis suggest the muscular adaptations that made modern humans better runners.

3D simulations reveal Australopithecus afarensis (“Lucy”) could run upright but at just 5 m/s—much slower than modern humans. Key insights into early bipedalism! #HumanEvolution #Paleoanthropology #Lucy #Bipedalism #anthropology #running

The truth about human bipedalism. — PaleoZoen Post by PaleoZoen

Human exceptionalism biases our views of bipedalism (IMHO). Check out my post: YouTube link included in post #bipedalism #humanevolution #paleoanthropology #biologocalanthropology #anthropology

A feature that makes #humans human is our ability to walk upright, or the fact that we are obligate #bipeds. How did this come to be when all our cousins had other methods of locomotion? Hear what some leading experts have to say - youtu.be/2uzenS00WzE?... #Bipedalism Symposium!

If #bipedalism makes us slow, easy prey, why didn’t our ancestors go extinct? Why are we here? - It also made our ancestors get smart.
