A study revealed that the Y chromosome, which determines male sex, is degenerating and may vanish in a few million years. Research on Sry-deficient Amami spiny rats, which lost the Y chromosome but still reproduce, suggests humans might evolve a new male-determining gene, offering hope for survival despite the Y chromosome's decline.
