As spotted by coldrum in the Telegraph:
Orkney Islanders are more closely related to people in Siberia and in Pakistan than those in Africa and the near East, according to a novel method to chart human migrations.
The surprising findings come from a new way to infer ancient human movements from the variation of DNA in people today, conducted by a team from the University of Oxford and University College Cork, which has pioneered a technique that analyses the entire human genetic makeup, or genome.
Although it provides relative genetic contributions of one group to another, rather than timings, it confirms how the first modern humans came out of Africa 50,000 years ago, mostly from a group in southern Africa called the San.
But the subsequent movements around the world, via the near east, central Asia and then Europe, turned up some surprises including a strong similarity between the Sindih, a people who once lived in Pakistan, and Orkney Islanders, or Orcadians.
In turn, the Orcadians are closely related to the people who first colonised Siberia.

Another migration story from coldrum:
New research forces U-turn in population migration theory
Research led by the University of Leeds has discovered genetic evidence that overturns existing theories about human migration into Island Southeast Asia (covering the Philippines, Indonesia and Malaysian Borneo) - taking the timeline back by nearly 10,000 years.
Prevailing theory suggests that the present-day populations of Island Southeast Asia (ISEA) originate largely from a Neolithic expansion from Taiwan driven by rice agriculture about 4,000 years ago - the so-called "Out of Taiwan" model.
However an international research team, led by the UK’s first Professor of Archaeogenetics, Martin Richards, has shown that a substantial fraction of their mitochondrial DNA lineages (inherited down the female line of descent), have been evolving within ISEA for a much longer period, possibly since modern humans arrived some 50,000 years ago.
Moreover, the lineage can be shown to have actually expanded in the opposite direction - into Taiwan - within the last 10,000 years.
Says Professor Richards: “I think the study results are going to be a big surprise for many archaeologists and linguists on whose studies conventional migration theories are based. These population expansions had nothing to do with agriculture, but were most likely to have been driven by climate change - in particular, global warming and the resulting sea-level rises at the end of the Ice Age between 15,000-7,000 years ago.”
At this time the ancient continent known as Sundaland – an extension of the Asian landmass as far as Borneo and Java – was flooded to create the present-day archipelago.
Although sea-level rise no doubt devastated many communities, it also opened up a huge amount of new coastal territory for those who survived(1). The present-day coastline is about twice as great as it was 15,000 years ago.
“Our genetic evidence suggests that probably from about 12,000 years ago these people began to recover from the natural catastophes and expanded greatly in numbers, spreading out in all directions, including north to Taiwan, west to the Southeast Asian mainland, and east towards New Guinea. These migrations have not previously been recognised archaeologically, but we have been able to show that there is supporting evidence in the archaeological record too.”

This indicates an IE element in India from earliest times. Sindih people may be linked to the first megs. in N Britain. Later migrations in both directions were then following old paths.
