Orangutans, not chimps are our blood relatives

It is commonly believed that our closest relative is the chimpanzee.Jeffrey Schwartz proposes that we are related more to the orangutans than to the chimps.According to him humans and chimps share only a genetic similarity but humans and orangutans share much more than that.
The science of human evolution is confronted with the popular chimpanzee theory and the earlier but largely ignored orangutan theory. There is very little in morphology to support a unique common ancestor for humans and chimpanzees. A close relationship between humans and African apes is currently supported by only eight unproblematic characters. The orangutan relationship is supported by about 28 well-supported characters, and it is also corroborated by the presence of orangutan-related features in early hominids. The uniquely shared morphology of humans and orangutans raises doubts about the almost universal belief that DNA sequence similarities necessarily demonstrate a closer evolutionary relationship between humans and chimpanzees.
