A BBC News article says, Each of us has at least 100 new mutations in our DNA, according to research published in the journal Current Biology.
Scientists have been trying to get an accurate estimate of the mutation rate for over 70 years.
However, only now has it been possible to get a reliable estimate, thanks to "next generation" technology for genetic sequencing.
The findings may lead to new treatments and insights into our evolution.
In 1935, one of the founders of modern genetics, JBS Haldane, studied a group of men with the blood disease haemophilia. He speculated that there would be about 150 new mutations in each of us....
