4. They Weren't All Cavemen
Many Neanderthals used the limestone caves of Europe as shelter, but some clearly had a passion for architecture that could not be subdued. 44,000 years ago, for example, Neanderthals living in what is now Ukraine built a large communal shelter made from mammoth bones. Dozens of hearths were discovered inside, which suggests that this structure was likely used for many generations. Building such complex dwellings further proves that Neanderthals were not bumbling dummies, but sophisticated hominids who hung out in awesome bone huts.
