Ancient ape offers clues to evolution of two-legged walking 2019-11-05T05:00:00Z Answering the questions of why and how hominin bipedalism evolved depends a lot on what kind of locomotion was being used before terrestrial bipedalism evolved. Fossil ape hints at how walking on two feet evolved 2019-11-05T05:00:00Z It is after all linked to the pivotal development of bipedalism in our history. What Makes the Human Foot Unique? 2018-10-07T04:00:00Z Nonetheless, when it comes to bipedalism, this research suggests we should reconsider where this important trait originated. Climbing trees helped our ancestors evolve to walk on two legs rather than four, study suggests 2022-12-23T05:00:00Z Perhaps because a linear view of the evolution of human bipedalism was the dominant paradigm, other researchers embraced the bear hypothesis.

Why Facts Don’t Change Our Minds 2017-02-19T05:00:00Z A top-down approach to assessing how our early ancestors might have evolved bipedalism focuses on possible modes of ancestral locomotion by considering how living great apes move around. Fossil ape hints at how walking on two feet evolved 2019-11-05T05:00:00Z Some researchers have even argued that our distant ancestors originally evolved bipedalism in the trees for walking on branches. A 3.2-Million-Year-Old Mystery: Did Lucy Fall From a Tree? 2016-08-29T04:00:00Z A more recent idea is that bipedalism first emerged in the forests, which would be consistent with the fossil record and may also have a modern-day parallel. Tracing the tangled tracks of humankind's evolutionary journey 2018-02-12T05:00:00Z Oddly, research suggests bipedalism is a rather ineffective means of locomotion. This robot takes power walking to a new level 2016-07-13T04:00:00Z The mixed features of these prehistoric remains upset the received human origin story, according to which bipedalism ushered in technology, dietary change and high intelligence. Who Apes Whom? 2015-09-15T04:00:00Z Böhme et al.3 present fossils of a previously unknown ape called Danuvius guggenmosi, which the authors suggest provides a good model for the type of locomotion from which bipedalism might have evolved. Fossil ape hints at how walking on two feet evolved 2019-11-05T05:00:00Z That probably means that we should be on the lookout for breaking research linking autism and bipedalism because eventually, autism gets linked to everything.

The scientist behind the 'personhood' chimps 2015-06-12T04:00:00Z Thus, perhaps dinosaurs making the transition from bipedalism walked in such a way, too—walking on their palms with hyperextended fingers. Did Dinosaurs Walk on Their Fingertips at One Point? 2015-05-31T04:00:00Z Tuttle believes that bipedalism preceded the development of the brain in early humans –and was likely something inherited from smaller apes already used to using their feet to move laterally along branches in trees. A Magisterial Synthesis Of Apes And Human Evolution 2014-11-23T05:00:00Z The implications are that multiple forms of bipedalism were once practiced by our early hominin ancestors. [Introduction to Special Issue] Introduction: The Mosaic Nature of Australopithecus sediba 2013-04-18T15:56:22.657Z While this species would have been capable of bipedalism they likely walked with a hyperpronating gait, meaning an excessive rotation of the foot, and would have hobbled along with some difficulty.

How to apply an evolutionary hypothesis about gestation to your pregnancy 2012-09-05T13:45:00.190Z If major events continue to be used as industrial leverage, the torch relay could signal a summer of enforced rather than voluntary bipedalism. Olympic torch route, day 28: Newcastle puts some zip into the festivities 2012-06-15T06:00:01Z Likewise, a few scientists remain skeptical of the status of Ardipithecus as a hominin; they argue that it was actually an ape that evolved limited bipedalism. African Foot Fossil Indicates Another Hominin Species Lived With Lucy 2012-03-28T17:05:36Z Given the evidence for bipedalism in this species, the relationship between the pelvis and terrestrial habitation may warrant closer investigation. Pieces of the Human Evolutionary Puzzle: Who Was Australopithecus sediba? 2011-09-09T23:15:05.257Z Such small home ranges suggest that bipedalism evolved for other reasons, she said. Hominid females roamed while males waited-study 2011-06-01T17:57:46Z Why this notion that we could or should keep babies in our wombs longer if it wasn’t for bipedalism keeping our birth canals too small for gestating any longer, for growing bigger babies? How to apply an evolutionary hypothesis about gestation to your pregnancy 2012-09-05T13:45:00.190Z The findings also shed some light—and heat—on a longstanding debate over the origin of bipedalism in early humans. East African Human Ancestors Lived in Hot Environments, Says Caltech-led Team 2010-06-10T14:57:00Z The pelvis and hip look more modern, indicating that sediba was an expert upright walker—bipedalism is a hallmark of being human—like early Homo species. A Missing Link? Scientists Find a New Human Fossil 2010-04-08T14:01:00Z The researchers, however, said there was no way to speculate on how early that bipedalism developed. Bipedalism takes a big step backward 2010-03-30T04:00:00Z "We assumed more of the hominids would be from non-local areas since it is generally thought the evolution of bipedalism was due in part to allow individuals to range longer distances," Copeland said. Hominid females roamed while males waited-study 2011-06-01T17:57:46Z The OD says it’s the pelvis—implying it’s a unique constraint due to bipedalism. How to apply an evolutionary hypothesis about gestation to your pregnancy 2012-09-05T13:45:00.190Z "For a long time, anthropologists have hypothesized that bipedalism and other unique human traits would be advantageous to life in hot savanna environments," says Passey. East African Human Ancestors Lived in Hot Environments, Says Caltech-led Team 2010-06-10T14:57:00Z His idea was that they were separate events and they happened sequentially - that bipedalism freed the hand to evolve for other purposes. 2010-01-18T11:12:00Z These considerations led to the team's interest in figuring out just how hot it was in the part of the world where bipedalism is most likely to have first gained a toehold. East African Human Ancestors Lived in Hot Environments, Says Caltech-led Team 2010-06-10T14:57:00Z But, he notes, they are "consistent with the notion that the heat in the area would have been a selective pressure that could have made bipedalism advantageous."
