Unfortunately, it also gave us aching backs and sore knees, but more on that later. He is referring to recent research that has suggested our ancestors were already moving around on two legs long before they left the dense forests. None, however, is as riveting as what master storyteller Ngũgĩ wa Thiong'o offers in The Upright Revolution.Blending myth and folklore with an acute insight into the human psyche and politics, Wa Thiong'o conjures up a fantastic fable about how and why humans began to Human Evolution: Why Did Our Ancestors First Walk Upright? I think we walk upright because we wanted to. You have been walking on two legs since you took your first steps as a baby, but have you ever wondered why we walk the way we do today? Combining this with what we know about their anatomy has allowed scientists to make detailed comparisons between the gait of our early ancestors and our own way of walking today. "It sounds counter-intuitive, but perhaps the behaviour actually began in the trees," suggests Stringer. Why Do Humans Walk Upright? We thought that walking on all fours like a gorilla is more primitive than walking on two legs as humans do. There are even other primates that spend considerable time on open grasslands, like baboons, but they still move around on four legs. By Tom Bawden. Why Walk Upright? "We see the foot as a simple lever that allows us to 'toe off' as we walk," he says. Updated Friday, 6th September 2019, 3:54 pm. “If upright walking is so energetically favorable, why do apes still “knuckle-walk”?” Questions like this have been part of the creationist canon for some time. The ape-like creature the skull belonged to is now called Sahelanthropus tchadensis, and it lived between seven and six million years ago. But we still have a backbone left over from the years when our more distant ancestors were chiefly horizontal, both in the water and on the land. No one knows why we walk. The larger ones apparently lead the smaller ones along a trail that meanders for 27m (88ft) across the once-powdery surface. In the 1980s, Peter Rodman and Henry McHenry, both at the University of California, Davis, suggested that hominids evolved to walk upright in response to … Posted on the 15 October 2013 by Reprieve @EvoAnth Walking upright is one of the defining features of humans, separating us from the rest of the living apes. Published by Adam Benton on 15th October 2013 15th October 2013 Walking upright is one of the defining features of humans, separating us from the rest of the living apes. His short story The Upright Revolution: Or Why Humans Walk Upright, is translated into 94 languages from around the world. If they had a chance to grab a fistful of tasty treats before someone else snatched it, they stuffed the goodies into their mouths, and their hands, and ran to a safe haven on two feet. But by and large, quadrupedalism, or the ability to walk on four feet, occurs much more commonly in nature. The study, conducted by Kimberley Hockings of Oxford Brookes University, focused on wild chimps that routinely raid nearby farms. No more swinging in the trees. New evidence collected during two expeditions to Guinea in West Africa supports that theory, which has been one of several leading explanations for why humans became bipedal somewhere between three and six million years ago. Apes have long, opposable big toes to grab branches. Bennett believes that the human foot is actually a much more subtle and flexible tool than we give it credit for, perhaps because we tend to encase our own in shoes. "You can scamper up a tree if you need to, you could seek refuge up a rocky slope, or you could equally make progress when moving from one water source to another on slippery ground.". Enabling them to rapidly escape faster predators on four legs. Why do we walk upright? Eventually our lower limbs also grew longer, allowing us to take larger, more efficient steps. They are the earliest indisputable evidence that our distant ancestors had shifted from four legs to two, becoming "bipeds". Over the course of many generations, our ancestors slowly developed the right muscles and the right skeletal system to facilitate walking on two legs, and that gave us a very different profile from the quadrupeds we left behind. "I think we are adapted to unstable terrain and our feet reflect that," says Matthew Bennett, an anthropologist at Bournemouth University.
