The tip of a girl’s 40,000-year-old pinky finger found in a cold Siberian 2.______
cave, paired with faster and cheaper genetic sequencing technology, is 3. ______
helping scientists draw a surprising complex new picture of human origins,
Instead, the genetic analysis shows, modern humans encountered and
breed with at least two groups of ancient humans in relatively recent times: 4.______
the Neanderthals, who lived in Europe and Asia, dying of roughly 30,000 5.______
years ago, and a mysterious group known as the Denisovans, who lived in
Asia and the most likely vanished around the same time. 6.______
Their DNA lives on in us since they are extinct. "In a sense, we are a hybrid 7.______
species," Chris Stringer, a paleoanthropologist who is the research leader in
human origins at the Natural History Museum in London, said in an interview.
The Denisovans were first described a year ago in a groundbreaking
paper in the journal Nature, which made it possible by genetic sequencing 8.______
of the girl’s pinky bone and of an oddly shaped molar from a young adult.
Those findings have unleashed a spate of new analysis. 9.______
Scientists are trying to envision the ancient couplings and their
consequences: when and where they took place, how they happened, how many
produced offspring and what affect the archaic genes have on humans today. 10.______
Other scientists are trying to learn more about the Denisovans: who
they were, where they lived and how they became extinct. [br]
