Concerted Evolution
Concerted evolution is a phenomenon in which changes to molecular sequences of DNA occur simultaneously at multiple sites, allowing for a more rapid molecular evolution than random mutation. It is believed to be an important mechanism of evolution, allowing for the quick adaptation to various environmental pressures. Concerted evolution is most often seen in tandem repeats of DNA sequences, which are found in a wide variety of species from bacteria to humans, and is thought to give rise to genetic diversity. This evolutionary phenomenon is especially important in disease-causing organisms, as it can enable them to quickly evolve resistance to antibiotics and other therapies. Concerted evolution has implications for a variety of fields, including genetics, evolutionary biology, and medicine.
