Interactive map of human genetic history

A global map detailing the genetic histories of 95 different populations across the world, showing likely genetic impacts of European colonialism, the Arab slave trade, the Mongol Empire and European traders near the Silk Road mixing with people in China, has been revealed for the first time.

The interactive map, produced by researchers from Oxford University and UCL (University College London), details the histories of genetic mixing between each of the 95 populations across Europe, Africa, Asia and South America spanning the last four millennia.

The study, published this week in Science, simultaneously identifies, dates and characterises genetic mixing between populations. To do this, the researchers developed sophisticated statistical methods to analyse the DNA of 1490 individuals in 95 populations around the world. The work was chiefly funded by the Wellcome Trust and Royal Society.

Arturo is a 29-year-old male polar bear currently living in Argentina’s Mendoza Zoo. He is suffering in 40C (104F) heat in an enclosure that has just 20 inches of water for him to swim in and has as a consequence been displaying worrying behavior.

Please sign this petition or at least spread the word in order to have Arturo transferred to a zoo in Canada which has better facilities for an animal that is used to polar conditions.

PLEASE SIGN THIS PETITION!! this bear is dying out here! he’s not fit for a weather like ours and they still refuse to let him go because they’ll try to squeeze as much money as they can before he dies!

I saw him in 2007 and he was so sad and neglected it made me cry, I don’t understand why he is still there (I’m lying, of course I do: money. He’s the zoo’s primary attraction). He lives in really shitty conditions. What is he doing in my country in the first place? The south may be cool but not enough for him, and Mendoza is obviously one of the worst options. This is just plain animal cruelty.
