Many different types of genetic variation can be observed in the deoxyribonucleic acid (DNA) of modern humans. Nevertheless, humans have relatively little genetic variation compared with many other species, suggesting a recent common origin for Homo sapiens. Some of this variation may have functional consequences, for example in disease states and complex characters such as stature or intelligence, but much variation in DNA appears to be neutral.
