Genetic 'map' of Asia's diversity

Their findings support the hypothesis that Asia was populated primarily through a single migration event from the south.
The researchers described their findings in the journal Science.
They found genetic similarities between populations throughout Asia and an increase in genetic diversity from northern to southern latitudes.
The team screened genetic samples from 73 Asian populations for more than 50,000 single-nucleotide polymorphisms (SNPs).
These are variations in pieces of the DNA code, which can be compared to find out how closely related two individuals are genetically.
