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 chromosomeTheir 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 oldBy Ellie Zolfagharifard.
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.
The study, conducted by Dr Eran Elhaik from the University of Sheffield and Dr Dan Graur from the University of Houston, claims to put ‘Adam’ in his rightful place in evolutionary history.
STUDY SUGGESTS ADAM AND EVE LIVED IN AFRICA AT THE SAME TIME. Results of a separate study announced in August last year suggest that Adam and Eve lived in Africa at the same time – but probably never met.
A study of 69 men from around the world found ‘Y-chromosomal Adam’ walked the Earth between 120,000 and 156,000 years ago, much earlier than previously believed.
A study at Arizona University claimed the human Y chromosome originated from a different species through interbreeding which dates ‘Adam’ to be twice as old.
‘If we take the numerical results from previous studies seriously we can conclude that the past may be altered by the mother of “Adam” deciding not to conceive him in the future, thus, bringing a retroactive end to our species.
