Saw this article today that talks about how the population of natural redheads is dwindling and may become extinct by the year 2100, based on research conducted by the Oxford Hair Foundation (whoever they are). According to Oxford, only 4% of the World’s population has red hair (known fact) and since the gene is recessive, it is diluted if carriers produce children with people who have the brown hair dominant gene.
As a redheaded male, I think the position taken by this research group is a bit extreme but not outside the realm of possibility. For my part, I have contributed to the redhead population by bringing my daughter Rebecca and her beautiful red hair into the world.
