@intels5: Homo sapiens was once part of a much larger human family. Other human groups lived during overlapping periods, sometimes meeting and interbreeding. Today, every living person belongs to Homo sapiens, but many people still carry DNA inherited from encounters between our ancestors and Neanderthals. Fossils and ancient DNA continue to reshape that family tree. Scientists debate some species boundaries because groups could interbreed while retaining distinct physical features. Differences in skull shape, pelvises and even tiny middle-ear bones help researchers distinguish Neanderthals from modern humans despite their shared ancestry. Source: Natural History Museum.
