abstract
The objectives of this article are to prove that Darwin’s theory of Sexual selection is opposite to the Descent of Man (Human evolution) from the lower animal like a chimpanzee. According to Darwin, humans evolved from a lower animal through sexual selection. However, literature claims that sexual selection is absent in all kinds of animals; as sexual selection is not possible in monogamous, monomorphic, polymorphic animals and about 300-500 vertebrates (hermaphrodite) species. Even 65 experiments of meta-analysis and the Mayer experiment on Giant Silk Moth, Callosamia promethea, and many other experiments opposed sexual selection. Again, sexual selection is possible in polygamous animals, and the choice of mate, and battle for mating is possible here. However, it is absent in polygamous animals. Because, sexual selection requires sense, intelligence, love, etc. But except modern man, such attributes are entirely absent in the animal kingdom, its evidence is that animals are unable to know (at mature stage/young stage) their brothers, sisters, fathers, mothers, etc.; even they mate with them, which strongly opposes sexual selection. As the progenitor of humans were animals; so, they had no sense, intelligence, love, etc. to choose a mate, and thus, humans had not evolved through sexual selection. Alfred Russel Wallace also strongly opposed sexual selection. Sexual selection has come far from the Victorian ideas. Moreover, the mechanism of the Descent of Man is based on the wrong theory of Lamarck, and the belief of Darwin. Besides, fossil evidence, modern genetics research, Mendelian genetics (DNA), common sense/logic, Handle dilemma and the existing Tupaia opposes the Descent of Man from a lower animal. Again, how did the extinct progenitor of humans produce modern humans, why did humans and other organisms evolve millions of years ago but still existing in their own respective and unmodified forms? If evolution/ Darwin’s theory is valid, then humans and other living organisms should be immortal but not so happen. Hence, numerous biologists also rejected the sexual selection theory of Darwin.
