Human
Humans are known as Homo sapiens[1].As a species there are a number of different hypothesis' as to the origin of Homo Sapiens and their historical descent. One of these, and arguably the most well-supported theories through mitochondrial experimental research is the 'Out Of Hypothesis'. The theory that argues that every living human being descended from a small group of Homo sapien (abbreviated Hss) individuals in Africa, who then dispersed into the wider world meeting and displacing earlier forms such as Neanderthals and Denisovans[1].
