I only know of 5 skull types that exist.

However there is 6 billion brains controlling these characteristics and many of those brains attempt to separate themselves from this reality and demand individuality as determined by bigotry and selfish reasoning.
Thus a false reality of a sub-culture leading to a non-reality of separation from others who live within the exact time and space we share at this moment.
The labeling of ones self or a group in a attempt to create a false uniqueness. Completely removes their individuality of their birth.
These groups usually say they are labeling themselves in a attempt to create equality.
In reality a label and a,.. this is who I am confirmation, is nothing more than psychological racism.
I personally accept everyone as equal at all times , until they try to change reality to suit their needs of separation from others in a attempt to establish this sub-culture and individualistic and unique.
Other than these scientific attempts to explain mans origin I accept the 5 different skull shapes as a generality to attempt to understand mans place and times as a reality instead of a dream.
Any other designation of self is racism and for scholars to make exact committed explanations about and then be labeled as heretics and idiots who the next generation of scholars proves their finding as completely wrong and a new set of rules is issued and college text books re-written.
