"Films Media Group." . . "A tomb of 49,000 year-old Neanderthal bones discovered in the caves of El Sidrón in Northern Spain led to a double mystery: How did this group of individuals die? And, could the fate of this group help explain Neanderthal extinction? Some bones have deep cuts, long bones are cracked and skulls crushed-distinct signs of cannibalism. Was it a result of ritual or hunger? Neanderthal experts are adamant that they were not bloodthirsty brutes. Will this investigation challenge their views? What happened here will take us from El Sidron to the other end of the Iberian Peninsula where scientists are searching for underwater sites off Gibraltar. Scientists working here had theories-but no proof-for why Neanderthals went extinct. El Sidron may change this."@en . . "Videorecording"@en . . "Caveman Cold Case"@en .
