The study suggests our most recent common ancestor

The study suggests our most recent common ancestor is 8,300 years older than scientists previously believed - and puts him within the timeframe of the "Mitochondrial Eve". According to the researchers: “we can say with some certainty that modern humans emerged in Africa a little over 200,000 years ago". The discovery, published in European Journal of Human Genetics, contradicts a study from 2013 that claimed the human Y chromosome originated in a different species through interbreeding.
