Neanderthals and Cro Magnons are two different types of primitive human beings. Neanderthals are supposed to be more primitive than Cro Magnons are.
This picture shows a statue of what a Neanderthal is thought to have looked like.
The next image is a drawing showing a Neanderthal, a Cro Magnon, and Modern Man.
The most obvious difference between Neanderthals and Cro Magnons is the head. The head of a Neanderthal sticks forwards from the body,
while the head of a Cro Magnon is more aligned with the center of the body.
The next image compares the skulls of Neanderthals and Cro Magnons.
The material for this post is being held back until a video on the subject is created.
In the mean time, this link to a blog by a man named Eric Huffshmid should stimulate the mind of the curious individual.
