What animal has the closest DNA to human?
Although figures vary from study to study, it’s currently generally accepted that chimpanzees ( Pan troglodytes ) and their close relatives the bonobos ( Pan paniscus ) are both humans’ closest-living relatives, with each species sharing around 98.7% of our DNA.
Is FIV harmful to humans?
Although FIV is similar to HIV (the human immunodeficiency virus) and causes a feline disease that is similar to AIDS (acquired immune deficiency syndrome) in humans, it is a highly species-specific virus that infects only felines. There is currently no evidence that FIV can infect or cause disease in humans.
