I read today that "The Nobel prize in Physiology or Medicine has gone to Sweden's Svante Paabo for his work on human evolution."
Neanderthals and, to a lesser extent Denisovans, have been in scientific news for a year or more. There are fewer finds of Denisovan material, hence less is known about them, although they definitely existed as hominin ancestor of Homo sapiens, the modern humans, i.e. us.
(The first traces of Denisovans were found at Denisova Cave in Siberia in 2010. Fossilized teeth from Denisovans were later discovered in the same cave. Two upper and one lower molar were found in sediments that were dated to between 195,000 and 52,000 years ago)
