All humans are 99.9% alike, DNA study reveals

According to Wits University education specialist Ian McKay, all humans are 99.9% alike.

The National Health Laboratory has been doing these tests on people who would like to find out their family origins.

Except for the colour of the skin, we are not as different as some people have tried to claim over the years, says Mckay.

If you look at us genetically you'll find that we are almost identical and the differences are brought about by a few, tiny genetic differences.
