Genetically, the thing that makes a man a man is a single Y chromosome. Scientists have long suspected that this chromosome that only men carry is deteriorating, but until now no one has understood the rate of it’s demise.
Penn State scientists have discovered that the Y chromosome has evolved at a much more rapid pace than it’s fellow X chromosome, which both males and females carry. This rapid evolution has led to a dramatic loss of genes in the Y chromosome, which, if maintained, could lead to the chromosome disappearing.
“It’s certainly possible, but it’s difficult to predict when it will happen,” said Kateryna Makova, an associate professor of biology at Penn State University.
A world with no men. What implications do you think that would have? A world with no war and unified peace perhaps? Who knows?
