Suppose we did emerge from Afroka as one species.
There were still the intelligent and stupid among that one species, the strong and the weak, the haughty and the forgiving, the caring and the indifferent, the spiritual and the mundane, the METAL listeners and the wimps.
We're not equal.
We're created equal in the way that we are all caused, in the way that we are all going to die, and in countless other ways. This means that we should relate to one another with some basic reverence and respect. This does NOT mean that we're all equal in ability, purpose, function, role, or authority.
No anthropological discoveries will ever change this fundamental truth.....
