These skulls don't seem to fit with any evo-models. I can't post the pics but they really tell the whole story.
Anthropoligists however have admitted that the shapes of the Peruvian skulls is unlike the deformity caused by binding.
The skulls shouldn't exist
The skulls are a real problem for the anthropoligist. The frontal part of the skull seems to belong to an individual of the pre-Neanderthal family. But the lower jaw, though more robust than modern human type, has a modern shape and characteristics.
The shape of the cranium is completely different from Homo Erectus, Neanderthal types, and the modern human type. Some minor Neanderthal characteristics are present, as with the occipital ridge on the bottom back of the skull and the flattened bottom of the cranium, but other characteristics point more towards Homo Erectus.

What a representative of a premodern human type is doing on the South American continent? According to the orthodox anthropology, this skull simply does not exist, because it cannot be. Textbooks' oldest date of appearance of humans in North America is about 35000 BCE and much later for South America, based on the diffusion theory assumptions.
Neanderthals did not exist in South America. The only accepted human types entering the continent are of the modern anatomy.

Before someone bashes the source, please look at the pics because they exist apparently irregardless of the source, and do seem somewhat unexplainable.
