All South Africans are settlers, regardless of their skin colour, and their DNA carries the proof.

Birth certificates need to record accurately whom the biological parents are, not only for the legalities, but also because of any medical issues, and concerns of ancestry that may arise.

By comparing this DNA with that of thousands of people from various ethnic backgrounds living in England today, they found that genetic diversity was greater in the ancient population.

There are special diseases that are so old that it is known that even Egyptian mummies and tsars’ families were suffering from them. No medications have been yet created to cure them, and no doctor can help get rid of such diseases.

A fossilised tooth found in a swamp has allowed scientists to work out the DNA of a primitive North American elephant.

Doug Jackson has always wanted to know more about his family history, but that longing grew acute when his 6-year-old son was asked to wear a costume or flag from an ancestor's country for a school "cultural day."

A DNA sample provides results that are both startling and validating.

It’s called ancestry DNA testing and it is as true-blue as the reality of your long lost great grandfather himself.

Much like how a person's genetic code differs from other individuals, the level at which those genes are activated in the body differs from one person to another, scientists have learned. And though some of those differences in gene activity are seen between different populations – Asians versus Europeans, for instance – more of those variations are due to individual-level factors, further obscuring the biological meaning of "race."
