Question: They are a mysterious relative of the Neanderthals who are thought to have roamed the plains of Siberia and east Asia long before modern humans arrived on the continent. But little is known about the Denisovans, a sister species of the Neanderthals who first emerged around 200,000 years ago, as so few of their fossilised remains have been discovered. Now researchers have unpicked a tiny piece of the puzzle about how this enigmatic human species lived - they regularly inhabited the same caves. Using pioneering DNA analysis of teeth and a fragment of pinky finger bone found at the Denisova cave in Altai Krai, in the Altai Mountains near Barnaul, Russia, the researchers have discovered they belonged to three individuals who lived there tens of thousands of years apart.Geneticists studied DNA from teeth and a pinky bone from a Siberian caveThey were found to belong to individuals living thousands of years apartIt has provided clues about how this mysterious human species livedThe Denisovans are thought to be a sister species of the Neanderthal

Question: (CNN) -- Make no mistake. A handshake is just a handshake. Fifty-year-old geopolitical conflicts don't turn on a dime. American foreign policy isn't an Etch A Sketch where you get to wipe the board clean in every news cycle. Between countries, as with people, grudges and hard feelings don't fade easily. These things are true no matter how eager some in the media are to give President Barack Obama's sagging job approval rating -- just 41% in a recent Gallup Poll -- a boost by likening him to Nelson Mandela. Seriously? There is far-fetched, and there is farcical. Comparing Obama to Mandela falls into the latter category.Ruben Navarrette: Make no mistake, a handshake is just a handshakeNavarrette: President Obama's handshake with Raul Castro is no big dealHe says it does not mean that U.S.-Cuba relations will change for the betterNavarrette: Let's keep in mind the atrocious human rights record of Cuba
