The article discusses how DNA databases and genomic sequencing help us understand how new species evolve. The speed at which DNA changes is linked to how quickly new species form in animals and plants. Different factors like mutation rates, selection, and population size affect how quickly new species develop. The relationship between DNA changes and the creation of new species is complex and influenced by various factors like traits, habitats, and distribution. Understanding this connection is crucial for studying how biodiversity is generated and using DNA to track the evolution of species over long periods of time.
