Gene flow occurs through generations. Gene flow can occur across language barriers in humans. If we have a technique of measuring specific allele frequencies in different population of the world, can we not predict human migratory patterns in pre-history and history? Do you agree or disagree? Provide explanation to your answer.
Yes, I agree that gene flow occurs through generations. The human migratory patterns can be predicted by studying the allelic frequencies in prehistory and history. We can trace the evolutionary history and migratory patterns by the Human Genographics project. This project is a genetic anthropological study that was launched on April 13, 2005 by the National Geographic Society which aims to map history of human migration patterns by collecting and analysing DNA samples.
Note*: Shared gene pools gives the species its own identity. Reduced gene flow play important role in the speciation. Various modes have been presented whereby a single evolutionary descendent splits into two or more genetically independent lineages due to reduced gene flow.
