The formation of nasal septum deviation in human evolution

The purpose of this research is to determine when in the process of human evolution nasal septal deviation first occurred. There is a higher incidence of nasal septal deviations in man, while the septum of anthropoid ape is vertical and has not been found to have nasal septal deviations. It is said that our ancestors evolved respectively from ape like primates through Australapithecus, Pithecanthropus, Neanderthal man and finally Modern man. I concluded from my observations that the nasal septal deviations in man first occurred at the Neanderthal stage.
