genome evolution
Genome evolution is the process by which the genetic material of an organism changes over time. These changes can occur through mutations—small errors in DNA copying—and rearrangements, which can introduce new genes or alter existing ones. When these genetic changes provide a survival advantage, they are more likely to be passed on, leading to gradual evolution of species. Over generations, this process results in the diversity of life we see today, as genomes adapt to different environments and challenges. Genome evolution drives the development of new traits, species, and biological complexity.
