  • Recent study has shed light on the dramatic evolution of the Y chromosome, also known as the male sex chromosome.
  • Scientists discovered that only 14–27% of Y chromosome regions in different ape species are similar to those in humans.
  • This shows that humans and other ape species have evolved very differently.
  • X chromosomes, on the other hand, are very different.
  • Remarkably, the X chromosome, which is present in both males and females, has remained more stable.
  • X and Y chromosomes play roles in sexual development and fertility, along with many other biological functions.
