To calculate age of the Y chromosome, researchers multiplied data on age fathers have their first child with the number of mutations they uncovered
They then divided this figure by the mutation rate of the Y chromosome
Their findings suggest that 'Adam' lived in the same time frame as  'Eve'
Earlier study at Arizona University claimed Y chromosome originated in a different species through interbreeding and dated 'Adam' to be twice as old
Our most common male ancestor, ‘Adam’, has finally got his original birthdate – and its 9,000 years earlier than scientists believed.

UK researchers claim that ‘Adam’ walked the earth 209,000 years ago, contradicting a recent study that suggested the Y chromosome predated humanity.

Their findings puts 'Adam' within the timeframe of his other half 'Eve', the genetic maternal ancestor of mankind.
