- A small island away from the Korean coast is home to a genetic specific population of humans.
- Haenyeo – literally “sea women” – Korean cultural divers who have developed adaptation, allowing them to dive longer than more people.
- Unique genes appear in the islands that protect against changes in blood pressure that can affect pregnancy.
A maritime culture tradition extending over generations can give people in a separate South Korean island a unique set of genetic “superpowers” – low blood pressure and cold tolerance mutation that can help science develop new medical remedies in the future.
The Henyo – literally “sea women” – divers live on the island of Jeju, 53 miles (85 km) south of South Korean mainland.
From adolescence, they train to dive deep for the food crop from the seam.
A Transallantic Research Team has found Haenyeo’s generation-lumb cultural practice has helped them to develop adaptation, making them capable of diving longer than other humans.
But they have developed genetically to reduce blood pressure and increase tolerance of cold water.
If the findings of the researchers are correct, it is one of the only two groups, one of the only two groups of people who are, have been developed to dive, quite literally,.
Haenyeo difference
Genomic analysis found that Henio developed at least three distinctions.
The first is a non-non-melodious adaptation-bradycardia: a slow heart rate, below 60 beats per minute.
While this phenomenon can be caused by the medical condition, it may result in heart training. Bradycardia manifests as part of a evolutionary response during its deep divers called mammalian dive reflex.
“When anyone divers, the combination of catching your breath and submerging yourself in water triggers the mammalian dive reflex.”
“A component of that, is that your heart rate slows down.”
This mammal – in this case helps humans – Kansara oxygen, gives more time than giving more time before another.
“Compared to people with the same genetic background, trained divers had higher heart response,” Elardo said.
There is no genetic base for this adaptation and researchers feel that any human being can separate the same life from the same ability to life.
Other adaptations may be associated with generations of genetic development.
At depth, sea pressure causes tightening of blood vessels, which limits the flow of oxygen into the brain, lungs, and heart.
“So, your body says’ Ok, not too much oxygen is coming, let’s keep it in the organ that is needed the most”, “Ellardo explained, saying that blood pressure grows during deep dives so that sufficient oxygen supply to the vital organ can be ensured.
Growing blood pressure is usually not an issue for divers, but haenyeo continues their dep-sea practice, while pregnant-high blood pressure can be dangerous in pregnancy.
Usually studies are studied among women with sleep apnea, breathing has shown association with pregnancy complications. For pregnant women with sleep apnea, Ellardo said that it seems as if they inadvertently “dives their sleep.”
But it appears that Haenyeo opposes the event thanks to genetic mutation. The group of Elardo compared the genomes of Jeju Island residents to a non-Jeju population.
His study found that Jeju people have descended from genetic distinctions, and that two mutations – the first is associated with cold tolerance, the second has developed so much among the community – with diastolic blood pressure.
“We think … Vikas worked to protect the thesis pregnant women, while he dives,” said Ellardo. “His diastolic blood pressure did not increase as much as people with a different genetic background. And it was regardless of training.”
Natural selection on a separate island
Charles Darwin, British naturalist, first to inspect evolutionary adaptation in a unique atmosphere between Finch of the Galapagos Islands.
Darwin said that these islands spread by birds had different beak shapes and shapes. It was suggested that various population developed specific adaptations over time to help them feed on specific food sources for their islands.
In a similar vein, Jeju people show how humans can develop genetic adaptation, in which case the reaction to long-based cultural practices.
“At one point, diving was the greatest economic strength to define the island of Jeju,” said Elardo. “We think at some point in the past, everything necessary in Jeju was necessary.”
On a similar study, Ellardo found that Bajau people of Southeast Asia developed large spills to catch more oxygen -rich blood, helping them hold their underwater breath for a long time.
Other researches have studied cultures in places such as Tibet, Ethiopia and Andes, where people have developed unique genetic mutations to enable existence at high altitude. For example, Cutchua people of Peru and Tibetans have separate mutations for the same gene, but both height provide more capacity for tolerance where oxygen levels are low.
Elardo hopes that this research can be expanded to other diving cultures worldwide and compare the thesis with people living at high altitude with potential people. Therefore it can give rise to new medicine.
“Jeju is one of the lowest rates of stroke mortality in all Korea, so it is interesting to think about the gene that is happening, affecting the actual physiology of blood vessels.
“perhaps the [gene mutation] There is a protective effect that can be used, in principle, developer theraputics to treat strokes in people around the world. ,
