Answer:
Yes, we agree. As the gene flow occurs
through geographical barriers over generations, by studying specific allelic
frequencies in various populations of the world, we can predict the human
migratory patterns in pre-historic and historic era.
There have been projects undertaken such
as human genographics project. Which uses data from studies on specific
genes/chromosomes/mitochondrial DNA to trace the evolutionary history and
migratory patterns of humans.
