New gene discovery could replace the vanishing Y chromosome
The Y chromosome, crucial for determining male sex in humans, is slowly deteriorating, which may eventually lead to its disappearance. Scientists have identified a new gene on a different chromosome that could take over the Y chromosome's role, potentially reshaping the future of human reproduction and evolution.
In certain species like the spiny rat, males have already lost their Y chromosome but continue to thrive due to this new sex-determining gene. This discovery suggests that if the Y chromosome vanishes in humans, this gene could ensure the continuation of male sex. The study highlights how genetic evolution adapts to changes and points to the possibility that humans could follow a similar path in the future.
