New research on a 45,000-year-old Siberian thighbone has narrowed the window of time when humans and Neanderthals interbred to between 50,000 and 60,000 years ago, and has shown that modern humans reached northern Eurasia substantially earlier than some scientists thought.

Qiaomei Fu, a postdoctoral fellow at Harvard Medical School (HMS) and first author of a paper describing the research, said the sample had a long history before making its way into her hands.

But you may not think of the people.

Of course they’re there, and essential — thousands of scientists and support personnel, including Harvard physicists and students, some of whom played important roles in the 2012 discovery of the Higgs boson, the heaviest and most elusive particle discovered so far.
