It has only been a few decades - with the mapping of the human genome - and the popularity of DNA ancestry, that the notion of race has been debunked as meaningless except as a reference to cultural/social/religious differences.
I watched a video of someone who thought he was 'pure' Han Chinese - until he received his DNA analysis results. Turns out he was likely 10% Korean.
He was not happy! Or 不开心 .
If DNA has debunked the existence of race, how is it possible to use DNA to identify a person's racial ancestry?
Also, did you know that there are significant amounts of human DNA that are only present in people originating from outside of Africa?
DNA analysis places ancestors geographically, not racially.
Fun fact:
"...A DNA test has come back to haunt Pauline Hanson after the results showed she had Middle Eastern heritage....
Her genetic make up was traced back to a multicultural background, including 9 percent Middle Eastern, 32 per cent Italian, Greek or Turkish and 59 per cent from northern Europe..."

Only a fool would trust those ancestry DNA sites. And only an even bigger fool would come online to post about the results of one such test. 😐
DNA databases have helped solve decades-old cold cases when relatives of the perpetrators submitted DNA samples to these companies that then matched DNA found at the crime scenes.
Completely different context.

DNA to Solve Crimes
Since the advent of DNA profiling, this type of evidence has become an extremely powerful tool in the field of criminology.
Given that a person's DNA is the same in all areas of their body, it can't be altered or modified in any way. In this sense, it is a form of evidence resistant to tampering, although it can become degraded if collected and stored improperly. This degradation, however, will affect the ability of the DNA to be sequenced as opposed to being incorrectly sequenced.
Since no DNA is the same between two people – with the exception of identical twins – this form of evidence is now relied on as an accurate way to direct or conclude criminal cases.
Currently, DNA in a crime scene can help investigators to point their finger in the right direction or exclude an innocent person from a crime.
Identifying Victims of Crime
Another important function of DNA in criminology is that it can be used to identify victims of crime, many of whom would be otherwise unidentifiable because of the condition of their body when discovered. Hair and many other parts of the body can provide viable DNA evidence that is analysed and profiled to identify the victim of the crime.
Linking Two Crimes
DNA that is the same but found at two separate crime scenes can be used to link together the crimes. This can help criminal investigators determine if a serial criminal is at work or perhaps if the victims knew one another.
