East Asian people originate from the area that we now know as China, Japan, Mongolia, North Korea, South Korea, and Taiwan. Analysing these evolutionary footprints, he explained, is analogous to how 'studying the rings of a tree gives us insight into the conditions it experienced as it grew.' This suggests that ancestors of modern-day people in East Asia were first exposed to the disease around 25,000 years ago, according to the study. They found evidence among the DNA people of East Asian ancestry of natural selection for adaptations that would have served to lessen disease severity. The full findings of the study were published in the journal Current Biology.
The study found evidence of natural directoral selection.
