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.
In common usage, the word human generally refers to the only extant species of the genus Homo â anatomically and behaviorally modern Homo sapiens. Its usage often designates differences between that species as a whole and any other group or entity.o two humans â not even monozygotic twins â are genetically identical. Genes and environment influence human biological variation from visible characteristics to physiology to disease susceptibly to mental abilities. The exact influence of genes and environment on certain traits is not well understood.
