Mitochondrial Eve was the first mother. She is your relative, my relative, and your friends' relative. How you ask can this be possible? Well it is because of the "powerhouse", or mitochondria, in all cells that make this possible. You see, mitochondrial DNA (mtDNA) is only passed from mother to offspring without recombination. This means that it does not break and rejoin to form new DNA strands. So this means that every person can trace their mtDNA through their mothers and their mother's mother and so on, all the way back to the first female.
Mitochondrial Eve is believed to have lived around 200,000 years ago in Eastern Africa. She is not believed to be the first female ever, just the first female to produce a direct unbroken female line to the present day. She gets her name from the Biblical Eve and obviously after mitochondria.

Human Genome Project:
It was a thirteen year project in which the U.S. Department of Energy and the National Institutes of Health. The project originally was planned to last 15 years, but rapid technological advances accelerated the completion date to 2003. It had several project goals that included: identify all the approximately 20,000-25,000 genes in human DNA, determine the sequences of the 3 billion chemical base pairs that make up human DNA, store this information in databases, improve tools for data analysis, and more.
