A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
Archaic humans emerged out of Africa between 0.5 and 1.8 million years ago. This was followed by the emergence of modern humans (Homo sapiens) in East Africa around 300,000–250,000 years ago. In the 4th millennium BC written history arose in Ancient Egypt, [1] and later in Nubia's Kush, the Horn of Africa's Dʿmt, and Ifrikiya's Carthage. [2]
