They had a straight back and they came after homo erectus. They lived till the stone ages and they also had very less hair on their body.they were really tall and they had invented alot of things such as arrow heads which they used in huntings and they used to carve rocks to make these weapons.
Like most primates, humans use vision extensively in perception and communication. Humans have excellent colour vision, although visual acuity in low light is limited. Humans also use sounds extensively. Human languages represent one of the most complex systems of communication in the animal world, and the diversity of human languages is astounding. Touch is an important mode of perception, it is especially important in close social bonds. Humans have a moderately well developed sense of smell and taste, which is used to determine the suitability of foods and discover information about the environment and con specifics.
