By studying the genomes of more than 3,000 people across Japan, researchers have shed light on the population’s complex ancestry. The work may also pave the way for future precision medicine.
Nature’s first green is gold,
Her hardest hue to hold.
Her early leaf’s a flower;
But only so an hour.
Then leaf subsides to leaf,
So Eden sank to grief,
So dawn goes down to day
Nothing gold can stay.
