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.
Due to billions of years of evolution, humans share genes with all living organisms. The percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us.Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree.Besides similarities in anatomy and behavior, our close biological kinship with other primate species is indicated by DNA evidence.NA is thus especially important in the study of evolution. The amount of difference in DNA is a test of the difference between one species and another â and thus how closely or distantly related they are.
