Mitochondrial Eve refers to the matrilineal most recent common ancestor (MRCA) of all living humans. This means that every single person alive today can trace their direct, unbroken maternal lineage back to this one woman. Genetic studies estimate that she lived approximately 150,000 to 200,000 years ago in sub-Saharan Africa.

In human genetics, the Mitochondrial Eve is the matrilineal most recent common ancestor (MRCA) of all living humans. In other words, she is defined as the most recent woman from whom all living humans descend in an unbroken line purely through their mothers and through the mothers of those mothers, back until all lines converge on one woman.

Modern Science Recognizes that All Humans belong to a Single Species (Homo Sapiens), making Biological Races Invalid! Genetic research shows that human variation is continuous and not split into discrete racial categories.

Humanity can refer to the human race, the qualities that make us human, or the studies of human culture
