who are the croods?

In The Croods movie, there's a family who lived in caves then later on migrating when they later meet a traveler who goes by the name Guy. The Croods are a different species than Guy as The Croods resemble Homo neanderthals while Guy is a Homo sapiens hence his appearance and knowledge. Homo neanderthals or "The Croods" are a extinct species from 350,000 to 40,000 years ago. Homo neanderthals have a prominent brow ridge with a sloping forehead, physically short and very muscular. Compared to Guy, a Homo sapiens, they are significantly unintelligent compared to Guys behavior, ability to light fire, setup traps but also speech which The Croods shouldn't have but the movie's comedic sense has allowed them.

Homo neanderthals, The Croods, had a long but lower skull with a prominent brow ridge and sloping forehead. Their build is stocky, short but very muscular compared to other human species. Their femur is wider than a human which allowed them for bipedalism. The Croods having lived in caves had a form of art, cave paintings that were used for story and hand paintings.
