Modern humans, also known as Homo sapiens, are the only surviving species of the genus Homo and have several unique physical characteristics that distinguish them from earlier hominins. In Africa, where the earliest Homo sapiens fossils have been found, modern humans exhibit the following characteristics:
1. Prominent chin: Unlike earlier hominins, modern humans have a prominent chin, which is due to changes in the development of the lower jawbone.
2. Brain size of 1,350 cc or more: Modern humans have a larger brain volume than earlier hominins, with an average brain size of 1,350 cc or more.
3. Projecting midface: Modern humans have a projecting midface, which means that the face appears more flat and the nose protrudes further from the rest of the face.
4. Occipital bun: Modern humans have a rounded protrusion at the back of the skull called the occipital bun, which is absent in earlier hominins.
5. Shorter limbs: Modern humans have shorter limbs relative to their body size than earlier hominins, which may have been an adaptation for walking long distances and running.
These characteristics are thought to have evolved gradually over time, and may have been driven by a combination of genetic and environmental factors. Overall, the physical characteristics of modern humans in Africa are an important part of our evolutionary history and provide insights into how we became the species we are today.
