Sexual Selection as a Determinant of Certain Traits

If you are a man you should have a beautiful, impressive long tail appealing to many ladies, or have a shorter, less attractive tail that makes it easier for you . Escape from Predator Shorter tails look more logical because living in the wild among many potential predators, it is more convenient than good-looking features. This is the most reasonable choice, but it is not always the case. In many species, functions generally considered to be cumbersome or troublesome are actually advantageous.

"By choosing a specific type of men over other people, these functions can develop faster than other functions, as women can make a particularly strong choice. It is a group of women who prefer different personality, "Dr. Campania said. As the Galapagos Darwin scorpion is shaping a natural choice (and as it shapes yet) to drive the formation of these birds, the choice of women and the wings of the cappucino's ceder in the southern part of the man It seems to be the key to shaping a song. Enchanting evolution of Finch species

Sexual culling is an inevitable consequence of natural selection, and the two processes work the same way. Natural selection and sexual selection often give rise to different selective pressures: natural selection produces characteristics promoting reproductive and survival, but sexual selection enhances reproductive success but sacrifices survival (Birkenhead & Moller's Darwin's Ghiselin (1969) 1991). Selection of gender occurs when gender members disproportionately intersect with heterosexual members based on secondary characteristics (ie, behavior or structure other than reproductive organs or gametes). Sexual selection can be done in two ways; because of competition (internal) or gender competition or sales (middle-aged) between homosexuals, women choose the most suitable male (Clayton 1991 )

Depending on the physical sex of a person, evolution and inheritance are thought to bring about a difference in personality traits. Men are more likely to be more aggressive and competitive than females, as men's competition attracts women, as explained by gender selection theory. But now we may see that more and more women are becoming more active in competing with other men for men.

The choice of sex is a natural choice for factors that make the crossing of organisms successful. When the sexual appeal of a characteristic exceeds the survival responsibility, the characteristics of survival change. People live for a short period of time, but those who produce many children are more successful than those who produce longevity. The former gene will ultimately rule that kind of gene pool. Among many species, especially polygamous species, only a few male in all females are single, and sexual selection causes severe gender dimorphism. Among these species, men compete with other men for spouses. Games can be adjusted directly or by women. Among the species selected by women, men compete by showing outstanding phenotypic characteristics and / or performing wonderful courtship behavior. Then the most interested men, usually male and female colleagues with the most strange display
