In the latter‚ he explains sexual selection that results from the struggle to reproduce. According to Darwin‚ natural selection is one the basic agents of evolutionary change. At the same time‚ sexual selection is divided into the two aspects of intrasexual and intersexual selection. In essence‚ natural selection involves the

Sexual selection was an idea proposed by Darwin and refers to the process in which males and females attempt to maximize their chances of reproductive success. Within a species there are certain characteristics that make individuals attractive to potential mates. An example of this is in peacocks‚ female peacocks are attracted to males with long brightly colored tails‚ even though this makes them easier to be spotted by predators. This characteristic then evolves within the species due to how males

Natural selection forms the foundation of how we understand the ways that species have formed over time. Another form of selection is sexual selection‚ which is the selection of traits based on their roles in courting and mating. It involves attracting a mate with the greatest fitness while simultaneously portraying oneself as the best mate for selection. Fitness‚ described in natural selection‚ is the ability to reproduce and leave successful offspring that will continue the cycle. Sexual selection

Abstract: Having study natural selection and artificial selection we wanted to select for a trait on the plant Brassica rapa. We hypothesized that the leaf density is heritable and veritable. After our experiment we were able to conclude that our hypothesis was refuted because our average leaf density in our daughter population increased. Introduction: We are artificially selecting for a trait in the plant Brassica rapa. ( Wisconsin Fast Plant). Brassica rapa has been artificially selected

Rules of attraction: Biological and evolutionary reasons of mate choice ABSTRACT Within the past decade we have witnessed a series of new developments and an enormously growing interest in the understanding of human behaviour‚ especially when it comes to the basic principles of human mate choice. Mate preference is something which is often considered a very individual choice and appears to be influenced by cultural and economic norms. However‚ on the basis of numerous research works‚ it is

FEMALE MATE CHOICE IN POECILIA RETICULATA Abstract: In this experiment we examined female mate preference in the Trinidad guppy‚ Poecilia reticulata. Female guppies prefer to mate with brightly colored males in numerous species. From the jealousy experiment‚ the modeled female is jealous with the other female which is in the same section with 2 different males. The modeled female significantly preferred the males with 1 female than 3 males in other section. Introduction: Intrasexual selection

Option 5 Describe the difference between Darwin’s theories of (a) natural selection and (b) sexual selection. - Natural Selection The theory that members of a species each have slight variations from each other‚ and that these variations have the ability to enable some members of a species a survival advantage in certain environments. As a result of having a variation that increases their likelihood to survive‚ they are allowed to propagate‚ and their offspring have an increased likelihood of
