Neanderthals were humans like us, but they were a distinct species called Homo neanderthalensis. They had different characters to be observed:- •    They were shorter in size and height. •    Neanderthal has thicker bones, shorter limbs, an asymmetrical humerus, barrel chest, and thicker metacarpals. •    jaws were larger and more robust than those of modern humans and had a gap called the retromolar space.
