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.

Someone recommended me to read: 'Outliers' by Malcolm Gladwell.

I haven't yet.

But I was reading about it.

"Outlier" is a scientific term to describe things or phenomena that lie outside normal experience. In the summer, in Paris, we expect most days to be somewhere between warm and very hot. But imagine if you had a day in the middle of August where the temperature fell below freezing. That day would be outlier.

So we all know what an Outlier is.

In this book I'm interested in people who are outliers—in men and women who, for one reason or another, are so accomplished and so extraordinary and so outside of ordinary experience that they are as puzzling to the rest of us as a cold day in August.

Sounds good doesn't it?
