Early eukaryotes are believed to have evolved mitosis as a mechanism to ensure accurate distribution of genetic material during cell division. Initially, cell division in primitive organisms likely occurred through simple binary fission, but as genomes became more complex and nuclear membranes evolved, mitosis emerged to maintain genetic stability. Meiosis is thought to
