Study Reveals Rapid Evolution of Y Chromosome in Apes
The study in Nature reveals rapid evolution of the Y chromosome in apes, showing only 14-27% similarity with humans, unlike the stable X chromosome with over 90% similarity. Scientists sequenced genomes of six ape species, uncovering significant evolutionary differences. The Y chromosome’s rapid change is linked to sperm production, while the X chromosome remains stable. Repetitive elements protect genetic information, and the Y chromosome has developed self-repair mechanisms, stabilizing over 25 million years.
