Humans are Homo sapiens who live on the Planet Earth. They are closely related to Neanderthals(or known as cavemen) Most people think they come from their direct ancestor (Homo sapiens sapiens) Generally, modern humans are more lightly built than the archaic people from which they have evolved. Humans are a highly variable species; modern humans can show remarkably robust traits, and early modern humans even more so. Despite this, modern humans differ from archaic people (the Neanderthals and Denisovans) in a range of anatomical details. Most of these differences have been identified in the skull, which has copious anatomical details and is also often the only part of a skeleton that is found in archaeological digs.
