Background Our genetic mix of our parents, each of which
contributed half in our genetic. May we come from different regions of the planet
DNA mitochondria is unaffected by other genetic exchanges. Mitochondria have own DNA separate with others DNA.

Aim To trace back who is the real ancestor of
human being.

Definition Mitochondria are the powerhouse of the cell
which contain mitochondrial DNA (mtDNA), are passed only from mother to offspring.
Mitochondrial Eve is the name given by researchers to the woman who is defined as the matrilineal most recent common ancestor (MRCA) for all currently living humans.

Why use mitochondrial The egg (Fertilization) contains
mitochondria that have been passed from mother to daughter for countless generations.
Male sperm contains only enough mitochondria to power the sperm to the surface of the egg – it does not enter the egg.

Cases The genetic survey that produced the whole
Mitochondrial Eve scenario didn't just sample Africans and Europeans – it sampled genes from people all over the planet. When mitochondrial DNA was compared, the survey discovered a startling result. Fundamental similarities in mitochondrial DNA in living humans suggested that we all contain genetic material from a single woman who was living in Africa around 200,000 years ago.
