Scientists from the Netherlands have created a genetic map of Europe showing the degree of relatedness between populations in which nearly 2,500 subjects were analyzed by correlating their genetic variations.
Such tools help to provide insight into human migrations, survival advantages, and genetic barriers.... but my favorite part is the way they show people are so similar. On a pale blue dot fraught with conflict, it's a reminder we're not all that different in the big picture. More at The New York Times.

The New York Times is reporting on new data concerning the date of the evolutionary split between the human and chimapnzee lineages:
Scientists are re-evaluating a pivotal event in human evolution, the split between the human and chimpanzee lineages, in light of a startling new comparison of the…
This is a very simple, lucid video of Spencer Wells talking about his work on the Genographic Project, the effort to accumulate lots of individual genetic data to map out where we all came from.
I've also submitted a test tube full of cheek epithelial cells to this project, and Lynn Fellman is…
The figure above comes from the an article in The New York Times, The Genetic Map of Europe, which draws from a new paper, Correlation between Genetic and Geographic Structure in Europe. The authors sampled 2,500 Europeans across 300,000 points of genetic variation, then extracted out the…
So much genetic similarity in spite of different religions, languages, cultures, and national boundaries all of which function to restrict gene flow.
... except for the Finns. And it's not just genetic, I can tell you.
So much genetic similarity in spite of different religions, languages, cultures, and national boundaries all of which function to restrict gene flow.
boundaries weren't important for most of history. water and mountains were the biggest block.
Expanding on Razib's (and Bob's) point:
The national languages of Europe are, with a handful of exceptions, all Indo-European languages, so it makes sense that most Europeans are genetically related to most other Europeans. Now let's consider the two linguistic outliers among the national groups represented on the chart: FI and HU. (These two languages, along with Estonian. are Uralic rather than Indo-European; the other exception is Turkish, which is from a language group most of whose representatives are in Central Asia.) Hungary is in the middle of Europe, so they had to either displace or assimilate people from the surrounding Indo-European groups. Finland, by contrast, is off in the northeastern corner of Europe: to get there you must either cross the Baltic Sea (a much bigger obstacle than either the English Channel or the Oresund Strait), pass through the arctic regions of Sweden or Norway, or go around through Russia. Thus there were not large numbers of Indo-European speakers passing through Finland, and that accounts for why the Finns are genetically distinct from the other groups in the chart.
The study did not include Russians, but my guess is that genetically as well as geographically they would occupy the gap between PO and FI.
OK, everybody sing:
Finland, Finland, Finland.
The country where I want to be,
Pony trekking or camping,
Or just watching TV,
Finland, Finland, Finland.
It's the country for me.
You're so near to Russia.
So far from Japan,
Quite a long way from Cairo,
Lots of miles from Vietnam.
Finland, Finland, Finland...
