Will Boys Stop Being Born In The Future? Will Only Girls Be Born? A report from Science Alert raises concerns about this potential threat, suggesting that the Y chromosome in males is gradually diminishing. This could put the future of humanity at risk. However, it may take millions of years for the Y chromosome to completely disappear. If humans do not develop a new gene to replace the Y chromosome and its decline continues, it could lead to the extinction of human life on Earth. The report underscores the urgent need for scientific advancements to address this genetic challenge and ensure the continuation of the human species.
