What are ways that neanderthals are different from modern humans

Neanderthals are said to be the closest to modern humans compared to the other previous human species based on the evolution theory of Darwin. However, there are still several differences that neanderthals exhibit that distinguishes them from the modern humans. The Neanderthals have shorter and more solid body structure compared to the modern humans for the main reason that they are conditioned to live in colder environment. The neanderthals are not only different from us in physique but also in the size of the brain because their brains can be bigger than modern humans making it proportional to their bigger bodies too.
