Possible demostrate an allele frequency on a segment originated first among Pygmy populations?

[Ernesto Grandi]

is it possible to demostrate a particular allele frequency on a chromosome segment originated first among Pygmy populations?
who knows if these frequency evolved indipendently and randomly in a little part of a population without any ancestral connection with pygmies?

is it possible to demostrate a sure derivation of an allele frequency from pygmies in these pictures? what's the position among scientific community and the apricity community members for this type of "problems"?
