Mitochondria, the fundamental part of a cell which supplies the most of the chemical energy by generating ATP, also gives extremely valuable clues about the human genome. Since it is inherited maternally, all human beings on the earth could be traced back to an individual female lived in Africa who is called “Mitochondrial Eve” and  by the scientists. A recent study of scientists from Rice University suggests that our common “grandma” lived 200,000 years ago. Fascinating story.

The most robust statistical examination to date of our species’ genetic links to “mitochondrial Eve” the maternal ancestor of all living humans confirms that she lived about 200,000 years ago.

The Rice University study was based on a side by side comparison of 10 human genetic models that each aim to determine when Eve lived using a very different set of assumptions about the way humans migrated, expanded and spread across Earth. (more…)
