When symptoms are present, diagnosing the presence of osteophytes is a combination of a clinical exam of the joints and x-rays. Once the presence of osteophytes is confirmed, the treatment will depend on the severity of the disease.
While the genetic difference between individual humans today is minuscule â about 0.1%, on average â study of the same aspects of the chimpanzee genome indicates a difference of about 1.2%. The bonobo (Pan paniscus), which is the close cousin of chimpanzees (Pan troglodytes), differs from humans to the same degree.
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to it, and its current effects. For most DNA sequences, humans and chimpanzees appear to be most closely related, but some point to a human-gorilla or chimpanzee-gorilla clade. 2  The human genome has been sequenced, as well as the chimpanzee genome. 3  Humans have 23 pairs of chromosomes, while chimpanzees, gorillas, and orangutans have 24.
