Males to Vanish from Earth? Study Reveals

A groundbreaking study has revealed a startling possibility for the future of the human race: the Y chromosome, which determines male sex, is gradually degenerating and could potentially disappear in a few million years. This finding has led scientists to speculate about a future where only females may be born.

The Y chromosome, one of the two sex chromosomes in humans, contains the vital SRY gene responsible for triggering male characteristics during embryonic development. While females have two X chromosomes, males possess one X and one Y chromosome. However, the Y chromosome is significantly smaller, carrying only around 55 genes compared to the X chromosome's 900.

As the Y chromosome continues to deteriorate, researchers are concerned about the long-term implications for human reproduction and the possible extinction of males. The study, as reported by The Conversation, highlights the fragility of the Y chromosome and suggests that, without intervention, the future could see a world dominated by females.

This discovery raises profound questions about the survival and evolution of the human species, as well as the biological mechanisms that could potentially replace or repair the Y chromosome.
