Irregular galaxies were much more common when the universe was 2 billion years old. This is because the early universe was a time of great turbulence and change, leading to the formation of many irregular galaxies. Over time, these galaxies evolved into the more structured forms we see today, such as spiral and elliptical galaxies.
