Neanderthals are modern human's closest extinct human relative. Traits associated with Neanderthals, include angled cheekbones, a larger nose for humidifying and warming cold, dry air, shorter and stockier bodies, and proportional brain size to a modern human. Neanderthals are also associated with toolmaking abilities, creating a diverse set of sophisticated tools, controlling fire, living in shelters, wearing clothing, being skilled hunters of large animals, and making symbolic or ornamental objects. There is evidence that Neanderthals deliberately buried their dead and occasionally even marked their graves with offerings, such as flowers. DNA has been recovered from more than a dozen Neanderthal fossils, indicating interbreeding between Homo sapiens and Neanderthals. They also could have had the ability to communicate in human language just like modern humans.
