24,000-Year-Old Body Shows Kinship to Europeans and American Indians

The genome of a young boy buried at Mal’ta near Lake Baikal in eastern Siberia some 24,000 years ago has turned out to hold two surprises for anthropologists.

The first is that the boy’s DNA matches that of Western Europeans, showing that during the last Ice Age people from Europe had reached farther east across Eurasia than previously supposed. Though none of the Mal’ta boy’s skin or hair survives, his genes suggest he would have had brown hair, brown eyes and freckled skin.

The second surprise is that his DNA also matches a large proportion — about 25 percent — of the DNA of living Native Americans. The first people to arrive in the Americas have long been assumed to have descended from Siberian populations related to East Asians. It now seems that they may be a mixture between the Western Europeans who had reached Siberia and an East Asian population.

Granted, it's one skeleton's DNA, but it is definitely worth more research, I think.

Well of course we're still evolving

but scientists are realising we're evolving much quicker than pre-agrarian humans--partly in response to diseases that hit large groups of people who are living in close quarters. But pale skin and blue eyes are relatively recent mutations, for example.

Study finds humans still evolving, and quickly

Culture Speeds Up Human Evolution

Also on the scientific front, Voyager 2 has discovered a dent in our solar system due to magnetic forces.

Voyager 2 finds solar system's shape is 'dented'

I was 10 years old when the Voyager probes were launched, along with their Golden Records. An excerpt from the Voyager 1 greeting by Jimmy Carter (given in the Wikipedia article) goes like this:

We cast this message into the cosmos… Of the 200 billion stars in the Milky Way galaxy, some — perhaps many — may have inhabited planets and space faring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: We are trying to survive our time so we may live into yours. We hope some day, having solved the problems we face, to join a community of Galactic Civilizations. This record represents our hope and our determination and our goodwill in a vast and awesome universe.

The 70s were in some ways a very hopeful time, weren't they?
