St. Louis Dispatch reports:
Scientists used to think that men might become extinct, that people might have to find new ways to have sex, and that we might evolve into a new species, all as a result of the demise of the Y chromosome.
But a new study by researchers at Washington University in St. Louis and the Whitehead Institute for Biomedical Research in Cambridge, Mass., has determined that the Y is here to stay. The landmark research is the first to explore the contents of the Y chromosome of any species. The results appear in today’s issue of the journal Nature.
