Essay about Natural and Sexual Selection. - 678 Words
Natural and sexual selection One of the first and central mechanisms proposed by Darwin during his life was that of natural selection. Some may refer to this as survival of the fittest, whereby species that produce offspring have been successful in doing so because they have produced random individual features which have lead them to live longer and pro-create offspring with the same inheritable desired features. Not all individuals will be able to reproduce, therefore only the fittest willÃâ¦multiply, vary, let the strongest live and the weakest die, (Darwin, Charles (1968, 1859)) Origin of the Species. Therefore, different desired traits are passed down through generation-to-generation, and those traits, which are not soâ⬠¦show more contentâ⬠¦One example is that of language. Darwin (1871) wrote that humans might have been prepared for language by sexual selection reinforcing the most expressive, articulate non-verbal vocalists in so doing creating a song making ability in humans that could later be interpreted into language. So sexual and natural selection may have not just been about physical attractiveness 500,000 years ago, but rather, sexual attractiveness which was more focused on physical abilities and unique qualities. This idea of natural and sexual selection has paved a way over the years into todays society, where our choice of partner is still influenced primarily on sexual, physical and mental attributes, however, it has been a made a little more accessible and easier for us at present thanks to our homo sapien ancestors.

Natural selection is the production of organisms according to their physical attributes whereby off springs of the younger generations takes the strong, desired and inheritable aspects of their parents. They become more adapted to the environment although some does well than others according to their individual traits which are attributed to their phenotypes (Sinervo, 1997). According to Charles Darwin, fitness can be describedRead MoreThe Gorill Natural Selection And Sexual Selection1306 Words à |à 6 Pages Darwinââ¬â¢s theory is in regards to natural selection and sexual selection. The gorilla is an animal that uses the two selections to determine their protection, feeding, and reproduction. First Charles Darwin described the characteristics and structures that a animal like a gorilla is born with. He states that these characters and structures will have slow changes that will be different than when they were born. Then he believes that they will have characters and structures that are trifling importantRead MoreNatural and Sexual Selection of Vestigial and Wild Type Drosophila Melanogaster2428 Words à |à 10 PagesNatural and Sexual Selection of Vestigial and Wild Type Drosophila melanogaster Abstract In this experiment, vestigial flies as well as wild type flies were used to create some diversity as well as test one of our hypotheses. Our hypotheses are as follows; 1) The wild type flies will have a greater relative fitness compared to the vestigial flies based on only sexual selection.à The wild type has a relative fitness of 1 since it has fully functional wings.à Vestigial Winged flies are not as sexuallyRead MoreCharles Darwin and Natural Selection975 Words à |à 4 PagesNatural Selection, a key mechanism of evolution is the progressive process by which biological traits either become more or less common in a community or population as a result of inherited traits on different reproductive success of organisms with their environment. Charles Darwin in fact put together an articulate theory of evolution and supported it with a good amount of body evidence in 1859 when he published his book. Natural selection is too however a basic mechanism of evolution like mutation Read MoreEvolution Of Natural Selection Evolution1005 Words à |à 5 PagesNatural Selection-Evolution Natural selection is the evolutionary process through which factors in the environment exert pressure, favoring some individuals over others to produce the next generation. Charles Darwin (1809-1882) formulated this theory that has stood the test of time. Natural selection is important to anthropology for understanding how species change. Anthropologists emphasize the complexity of evolution and how natural selection is much more than ââ¬Å"survival of the fittest.â⬠CharlesRead More Sexual Selection and Sexual Conflict Essay1140 Words à |à 5 Pagescharacterized sexual selection as ââ¬Å"variance in the number of matesâ⬠. The purpose of sexual selection is to perfect the secondary sexual characteristics, which are the morphological differences between the two sexes. On the other hand the primary sexual characteristics are the differences between the reproductive genital systems of the two sexes. Sexual selection instead of adapting the individual to the environment, like natural selection, it does enhance traits involved in mate acquisition. Sexual conflictRead MoreHow Natural Selection Has Shaped The Modern Mind1575 Words à |à 7 Pagesdesign or natural selection. The notion of whether or not divine design or natural selection is the result of an organisms faculties has sparked significant debate since Darwin first proposed his theory of natural selection in the mid-nineteenth century. Even though there is a substantial amount of emp irical evidence supporting natural selection, some theologist are still not entirely convinced that Darwinââ¬â¢s theory explains the progression of mankind. Thus, this paper will explore how natural selectionRead MoreCharles Darwin s Theory Of Evolution1173 Words à |à 5 Pages It is time to start believing. Evolutionary theories were first proposed by Charles Darwin in the 19th century, and 150 years later, these ideas are still being studied and proven today. Charles Darwin set the basis for these discoveries. Natural Selection and survival of the fittest are two examples of evolution. Charles Darwin once exclaimed, ââ¬Å"It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.â⬠ThisRead MoreEssay on The Validity of the Theory of Evolution1539 Words à |à 7 Pagesanimal. Leading to the idea of Natural Selection. Natural Selection is The term adaptation may refer to a feature which is especially important for an organisms survival. The adaptation of horses teeth to the grinding of grass, or their ability to run fast and escape predators. Such adaptations are produced in a variable population by the better suited forms reproducing more successfully, that is, by natural selection.(Stansfield, Mulligan P.) Natural selection is the process by which most heritableRead MoreNatural Selection And Its Effect On A Population Essay1356 Words à |à 6 PagesNatural selection is the process whereby species that are better equipped for survival in their environment are able to prolong their bloodline by reproducing. Advancements in these species, evolution, can be seen as a result of natural selections force. Natural selection can be broken down into three concepts that require it to operate. The first is the constant struggle a species face for survival, which results in the continuation of the successful branches of the species, as the others become
