摘要:It has been a subject of debate that how primates/apes evolved into Homo sapiens, but interestingly there is a common ancestor of all great Apes. This common ancestor not only evolved into the most advanced ape: - Homo sapiens but also evolved into the advanced apes (Chimpanzee, Gorilla, and Orangutan). The evolutionary paradigm of human evolution is often explained by evolutionary biologist as an outcome of Darwinian concept of Natural Selection. According to Darwins concept the fittest organism survives which is popularly known as Survival of the Fittest. So if human evolution is a function of Natural Selection then the complexity needs critical determination that how come all the species that evolved from the common ancestors at the same time still survives? Hence as Darwins concept of natural selection doesnt support the phenomenal condition we do say Charles Darwin Needs Revision, we can predict that all the primates that have developed from the common ancestor are fit for survival in the present condition. Hence the complexion uncertainty that needs attention is to solve the mystery which leads to the evolution and survival of all the different form of the primates and categorically selecting them as members of varying advanced groups. The anomaly can be explained by the logic of mutation and application of the theory of Gregorian (Mendellian)-Morganian genetics. To solve the complexity a theoretical-genetics approach has been discussed in this paper is justified, proposing Sinha-Tripathy modification of Darwins theory of Natural Selection.
