The first evidence of humans walking upright dates back to around 4-6 million years ago, with species like Australopithecus. Walking upright was a significant evolutionary adaptation that allowed early humans to use their hands for tool-making and carrying objects, leading to further advancements in their development.

Did Homo Erectus walk upright?
yes they did the Cro-Magnons walked upright as long with the homo habilis, neanderthals, ((pecking man and java man.) homo erectus)answer 2 The upright stance was probably acquired while in the tree-dwelling phase of development. [side comment Chimps are not purely vegetarian!]When the apes left the forest; and that was not necessarily a sudden event; the upright stance still held advantage of allowing the animal to see further.This was more advantage than faster running which is a quadruped feature.
What were homo erectus' physical characteristics?
Homo erectus had a robust build with a prominent brow ridge, a long low skull, and a larger brain size compared to earlier hominins. They had a more human-like upright posture and walked on two legs. Their average height ranged from around 4.9 to 6.1 feet.
The physical appearance of the homo habilis?
Homo habilis had a relatively small stature, averaging around 4 feet tall and weighing between 70-100 pounds. They had long arms and legs, with a combination of ape-like and human-like features such as a protruding face with a sloping forehead and small brain size. Their teeth were more similar to modern humans than apes.
Why did the human beings evolve into standing in an upright position not in the horizontal way?
One prevailing theory is that walking upright allowed our early human ancestors to use their hands for carrying objects, tools, and food while moving efficiently over long distances. This freed up the hands, enabling the development of more sophisticated tools and aiding in tasks like food gathering and hunting. It also gave them an advantage in spotting predators or prey over tall grass and savannah terrain.
Who walks upright has long lower limbs opposable thumbs and large brains?
Humans typically possess these characteristics, as they walk upright, have longer lower limbs compared to their upper limbs, opposable thumbs that support fine motor skills, and large brains relative to their body size. These traits contribute to their bipedal locomotion, dexterity, and complex cognitive abilities.
