What specific features caracterize the living humans ?
We recognize specific features in every living humans that allow us to qualify them as the only human species on our Earth. These specific features consist on "the skeleton braincase, a small face tucked under the forehead, a chin under the lower jaw, small and separated brow ridges, narrow shoulders, trunk and pelvis". The Humans are also known for needing a long ans slow gain in maturity which is a typical specific modern human feature.--NoraM (discussion) 20 avril 2020 à 14:30 (CEST)
Where were living the different human species ?
We found fossils, DNA and bowns of different human species in many different regions. It allowed us to determine that H. spiens was living in Africa, Europe, Asia and Oceania. H. neanderthalensis' territories were in Eurasia. We also know that another spicies, Denisovan was living near Denisova cave and in Sunda. --ColetteB (discussion) 30 avril 2020 à 17:12 (CEST)
