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?
they were black, had big noses, and big heads with flattened tops 4ft -6ft average. they grew at a rate similar to an ape, and their teeth are smaller than homo habilis. they also walked upright.
The physical appearance of the homo habilis?
Homo habilis look somewhere between a human and an ape. Their bodies were covered in hair to provide warmth- they didn't wear clothes. Their faces were scrunched up the way ape faces are, and they have long arms and walked upright.
Why did the human beings evolve into standing in an upright position not in the horizontal way?
To need arms to function as efficiently as humans do. To evolve horizontally would require support from four (or maybe three) limbs, and evolving a third set of limbs to serve as arms in very unlikely in a mammal. I don't think a six-limbed mammal exists...
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.
