• Resumen

  • The population divisions behind humanity's spread across Eurasia may have occurred within just 150 years--an evolutionary blink of an eye. The finding comes from the most comprehensive analysis yet of the sex-determining Y chromosome, which is passed from father to son through the generations. Like all chromosomes, the Y mutates overtime. The more distant the relationship between two men, the more genetically distinct their Y chromosomes. This means the chromosome can be used to generate a family tree of men.
