People in East Asia may have been exposed to coronaviruses as far back as 25,000 years ago and their descendants may carry genetic traces today, a study suggested.
Researchers said their findings do not imply that East Asians are now better protected against today's novel coronavirus, although genes do influence how an individual's body responds to viral infections.
For the study, genetic variation in 26 populations around the world were analysed, but the effects of coronavirus exposure was detected only in East Asians.
“An arms race with an ancient coronavirus, or with a different virus that happened to use similar interactions as coronaviruses with human hosts, may thus have taken place in ancestral East Asian populations,” the researchers wrote.
Importantly, adaptation to ancient viral epidemics does not necessarily imply any difference in genetic susceptibility between different human populations
Using publicly available genetics databases, the scientists analysed variation associated with genes coding for 420 virus-interacting proteins (VIPs), which are substances that may affect the way a person’s body reacts to an infection.
The proteins that were analysed were shown by earlier research to interact specifically with coronaviruses, leading researchers to name them CoV-VIPs.
Some may be involved in the immune response to infection, or they could be proteins used by viruses to hijack components of human cells after infection.
Only in the East Asian population did the researchers find patterns of genetic variation that suggested the CoV-VIPs had adapted to the presence of coronaviruses in the distant past.
The researchers think the effects began about 900 generations (or about 25,000 years) ago and lasted until about 200 generations (or 5,000 years) ago.
The findings could be of more than academic interest, as they may offer indications as to how humans will be affected by disease in future.
“By learning more about our ancient viral foes, our study highlights the promise of evolutionary information to better predict the pandemics of the future,” the researchers wrote.
The scientists, who are based at the University of Adelaide in Australia and the University of Arizona in the US, also said that identifying genetic differences between populations may help to develop drugs.
As the researchers noted, East Asia is where the current pandemic originated, yet the region has been notable for having been relatively less affected.
China, Japan and South Korea, which have a combined population of more than 1.5 billion, have suffered a total of about 16,000 deaths, according to official figures. Most other regions of the world have been much more heavily affected.
The researchers emphasised, though, that the results did not mean East Asians today have natural immunity to the coronavirus that causes Covid-19.
“Importantly, adaptation to ancient viral epidemics in specific human populations does not necessarily imply any difference in genetic susceptibility between different human populations, and the current evidence points toward an overwhelming impact of socioeconomic factors in the case of Covid-19,” they wrote.
Dr Andrew Freedman, specialist in infectious diseases at Cardiff University in Wales, who is not connected to the new study, said that an individual’s genetic make-up does, however, influence their response to viral infections.
For example, with HIV, the virus that causes Aids, a very small proportion of people are naturally better able to combat infection and can remain healthy for decades without treatment.
“That’s thought to be genetic – the genes control the immune response,” Dr Freedman said.
While he has not analysed the new study’s findings, Dr Freedman said that, because a person’s immune response is influenced by their genes, it was “certainly feasible” that particular populations were “better suited to combating Covid and other coronaviruses”.
The study was published online this year and presented this month at an annual meeting of the American Association of Physical Anthropologists.
It was released before being reviewed by other scientists, so its findings are considered preliminary.

How to wear a kandura
Dos
- Wear the right fabric for the right season and occasion
- Always ask for the dress code if you don’t know
- Wear a white kandura, white ghutra / shemagh (headwear) and black shoes for work
- Wear 100 per cent cotton under the kandura as most fabrics are polyester

Five famous companies founded by teens
There are numerous success stories of teen businesses that were created in college dorm rooms and other modest circumstances. Below are some of the most recognisable names in the industry:
- Facebook: Mark Zuckerberg and his friends started Facebook when he was a 19-year-old Harvard undergraduate.
- Dell: When Michael Dell was an undergraduate student at Texas University in 1984, he started upgrading computers for profit. He starting working full-time on his business when he was 19. Eventually, his company became the Dell Computer Corporation and then Dell Inc.
- Subway: Fred DeLuca opened the first Subway restaurant when he was 17. In 1965, Mr DeLuca needed extra money for college, so he decided to open his own business. Peter Buck, a family friend, lent him $1,000 and together, they opened Pete’s Super Submarines. A few years later, the company was rebranded and called Subway.
- Mashable: In 2005, Pete Cashmore created Mashable in Scotland when he was a teenager. The site was then a technology blog. Over the next few decades, Mr Cashmore has turned Mashable into a global media company.
- Oculus VR: Palmer Luckey founded Oculus VR in June 2012, when he was 19. In August that year, Oculus launched its Kickstarter campaign and raised more than $1 million in three days. Facebook bought Oculus for $2 billion two years later.
Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.
