Sexual Selection: Fact or Fiction

Sexual Selection: Fact or Novel The theory of sexual selection of Darwin is an interesting theory, as it provides an explanation of human struggle and cultural value system. According to theory, people with strong sexual desire have more descendants, so their character is inherited to the next generation than those who are not sexual. Contrary to other theories of Darwin - natural selection, people most adaptable to the environment are more likely to convey their genes, or "the most appropriate survival", and you may call it "the most sexy survival" I can do it. This theory is aimed at explaining why human beings deviate from others.

By contrast, sexual selection creates rapid evolutionary change as each generation progresses. Sex selection promotes evolution in a stable environment. Sexual choice diminishes the viability of animals (especially men) and has larger, more colorful or exaggerated features. The impressive thing about the cerebral cortex is that it does not focus on specific behavior. There are billions of universal neurons in the human cerebral cortex, and you can learn new ideas. When our cerebral cortex evolves by sexual selection, unlike other animals, is our ancestral mother and father sexually attractive to partners who can learn new ideas?

Natural selection is the power to choose which variants can survive and gain descendants able to breed. Sexual selection means that the gene obtained from the partner is actually selected by the selective partner organism. Therefore, the two selection formats functioning in the living world determine how the relative frequencies of different genotype and gene combinations vary within a particular population, and that process is the essence of biological evolution. In this way, the average fitness of the population will increase as long as adaptive genetic variation exists within the population. In other words, the adaptability to the environmental conditions of the population is increasing.

Evolution is a change in the genetic characteristics of consecutive generations of biological groups. These changes are caused by evolution processes such as natural selection (including sexual selection), genetic drift of mutations, genetic recombination, gene flow, etc. and bring biodiversity at all levels of species. , Individual organisms and molecules. In the mid-nineteenth century, Charles Darwin published scientific evolution theory of natural selection in his book, The Origin of Species (1859). Evolution of natural selection is first demonstrated by observation that there are more offsprings that are more likely to be produced than there is a possibility of survival.
