Sexual Selection: Fact or Fiction

Darwin's theory of sexual selection is an intriguing one because it offers an explanation of human striving and cultural value systems. The theory is that humans who are more sexually desirable will have more offspring and thus their traits will be passed on to future generations to a greater extent than those of less sexually desirable humans. As opposed to Darwin's other theory, natural selection, those who are the best adapted to their environment will be more likely to pass on their genes, or, "survival of the fittest", you might call sexual selection "survival of the sexiest." The theory is intended to in part explain why, when humans diverged from other primates, the human brain tripled in size in just two million years. At first glance, this theory also seems to explain much of the motivation behind human culture and achievement. Upon closer inspection, there are some fairly conspicuous problems with it, especially when it is extended to describe not only human evolution in the distant past but it the present, but it may still be the most plausible explanation available to explain why humans mental capacities have expanded so far beyond those of our primate relatives.

It makes complete sense that we would be biologically driven to prove our sexiness. At the most basic level, this could explain the plenitude and popularity of fashion magazines for young women and the emphasis on being good at sports in school for both genders. Beyond this, it could also explain why men and women are driven to succeed at their various careers, or to be perceived to be successful, smart, witty, fun-loving, good-looking, responsible, or any of a number of things that human aspire to be which are also s...

...corded history. Even if this theory was once true, it does not appear to hold true anymore, because those who we consider the most successful and desirable are not producing the greatest number of offspring, and so, the traits that are being selected for future generations may be entirely different. Ironically, we may be spending our lives trying to prove we have traits which evolution is actually selecting against.

  • The Characteristics Of Intra-Sexual Selection And Inter-Sexual Selection

    901 Words  | 2 Pages

    Natural and sexual selection are not random processes. If there is no difference between the individuals within the species there would be no selection. Sexual selection is related to mating, it acts on individual’s ability to obtain or successfully copulate with a partner. The idea of sexual selection was introduced by Charles Darwin in 1871; he revealed that there are organisms with traits which are not explained by the concept natural selection, for example the tail of a male peacock. His found two main ways in which sexual selection works, these are intra-sexual competition and inter-sexual selection. Intra sexual competition happens within species, usually between males. They compete against each other to be chosen as a mate by a member of opposite sex. Inter-sexual selection is choosing a mate among the members of opposite sex, usually done by females.

  • Why Darwinism Is Just A Theory?

    854 Words  | 2 Pages

    Keith Henson a writer in evolutionary psychology once said that “Evolution acts slowly. Our psychological characteristics today are those that promoted reproductive success in the ancestral environment.” Evolution was first introduced by a naturalist by the name of Charles Darwin. Darwin had written an autobiography, at the age of 50, On the Origin of Species (1859) explaining how species evolve through time by natural selection; this theory became known as Darwinism. “Verlyn Klinkenborg, who writes editorials and vignettes on science and nature for the “New York Times”” (Muller 706) questions Darwin’s theory in one of his essays he wrote called Darwin at 200: The Ongoing Force of His Unconventional Idea. Both articles talk about the theory of Darwinism, but the authors’ use different writing techniques and were written in different time periods. Darwin himself writes to inform us on what the theory is, where as Klinkenborg goes on to explain why Darwinism is just a theory. Today, evolution is still a very controversial topic among many. It comes up in several topics that are discussed everyday such as in politics, religion and education.

  • Sex, Gender and Sexual Orientation are Determined Genetically

    1171 Words  | 3 Pages

    Without having any value judgments on sexual deviancy- the word itself many seem to imply disapproval. Whether it be transvestism, voyeurism, exhibitionism, or sadomasochism, sexual deviancy is by many considered unnatural and inhuman. However these two words 'unnatural and inhuman' is exactly what homosexuality is not. The truth is, sexual deviancy is as much a function of biology and as much a product of nature - as the orthodox sexuality which society accepts as 'natural'. Of course some adult sexual orientation is caused by early social conditioning, but through research and hard evidence, scientists have found that sex, gender and sexual orientation are all determined genetically.

    Introduction The topic of gender differences must understandably be approached with caution in our modern world. Emotionally charged and fraught with ideas about political correctness, gender can be a difficult subject to address, particularly when discussed in correlation to behavior and social behavior. Throughout history, many people have strove to understand what makes men and women different. Until the modern era, this topic was generally left up to religious leaders and philosophers to discuss. However, with the acquisition of more specialized medical knowledge of human physiology and the advent of anthropology, we now know a great deal more about gender differences than at any other point in history.

  • The History And Impact Of The Space Race

    808 Words  | 2 Pages

    On May 25, 1961, just two weeks after the US had successfully got an American into space, John F. Kennedy gave a speech addressing it and exclaimed, "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project...will be more exciting, or more impressive to mankind, or more important...and none will be so difficult or expensive to accomplish..." (Kruse). The Space Race became an important event for all of humanity during the 20th century because it improved our knowledge of space, improved and inspired new technology, and improved our education. It sparked a mix of both friendly and non friendly competition between the Capitalist United States and the Communist Russia (USSR) from the launch of Sputnik in 1957, all the way to the Apollo-Soyuz project that ended the race in 1975 .

  • Breast Cancer

    1003 Words  | 3 Pages

    There are many different reasons that woman maybe at a higher risk for breast cancer than other woman. Family history is risk factors that increase a woman’s likelihood of getting breast cancer. What this means is if a woman is in a family where this disease is common among female or even males they are at a higher risk for being diagnosed with breast cancer than someone who is in a family where breast cancer is not common. If the relative that has this disease is one that is very close meaning they are either a sister, mother, or daughter the likelihood that said person will also contract the disease is then doubled. This is mainly due to the fact that in close relations you are able to inherit the genes BrcA-1 or BrcA-2, these genes are mutation genes that play a role in controlling the growth of cancer cell. Only a small portion of women inherit this gene about 1 in 500 to be exact, however when they do inherit this gene they have a 80% chance of developing breast cancer in their lifetime. This gene causes woman to develop cancer at a younger age usually before the time they hit menopause. Also, women with this gene have a greater risk of developing cancer in both breasts which is called bilateral breasts cancer. This is due to the fact that once the cancer develops in one breast the risk for developing it in the other breast increases. (“Breast Cancer”) "About 5 to 10% of breast cancer is hereditary, passed from one generation to the next via a variety of mutated genes". (Port 95-105) Lastly,

  • Homosexuality is Genetics

    1988 Words  | 4 Pages

    One of the most disputable issues among society nowadays is homosexuality. Is it sin and genetic virus that we have to prevent or just personal choice and a right to be different. But on the other hand it is also unnatural genetic mistake that should be prevented in order not to spoil the whole humankind. The other factor that can not be ignored is religion that claims homosexuality to be one of the unforgivable sins ever and prohibit such transgenics to exist within society, but does religion imply that people are entitled to judge and punish each other. Why society can’t just let them live and love each other nonetheless their love somehow differs from conventional ones? Conservative society tends to blame homosexual people, though science has proved that homosexuality is inherent in genetic foundation, but not personal choice therefore can not be denied, ignored moreover discriminated.

  • Summary: Biological Influences On Sexual Orientation

    The term sexual orientation is known as the preference of one’s sexual partners, whether the same sex, opposite sex, or both sexes. Sexual orientation occurs when a child reaches the adolescent stages in life (Broderick & Blewitt, 2015). Adolescents activate their sexual orientation within four steps that create their identity. Adolescents are unaware of their identity at the beginning stages of sexual orientation. They work their way into the exploration stage by learning their preference of sexual partners. Once they are aware of their sexual identity, they will start the process of acceptance. Once acceptance is achieved, they will begin to integrate their sexual orientation into their lives (Gallor & Fassinger, 2010).

  • Innovations Needed for Deep Space Exploration

    It is within man’s blood and nature to explore, and space is our next New World. Man’s first achievement in space travel was the launch of the Sputnik on October 4, 1957. For the next decades, space travel was roaring like a rocket, fueled by man’s desire to explore, man’s desire for knowledge, and man’s desire to beat his enemies. However, these impulses have died out as the well of government funding has been diverted to wars and debts, and the interest of the American people has been diverted to wars and debts. Amidst all these issues it is debated as to whether or not space travel is worth the money and the attention of scientists, particularly since humanity faces so many issues on earth currently. However, because of the past inventions, current services, and future benefits, space travel is indeed worth the money and attention of governments and people. It is within our hands to control man’s advancement, and space travel is the next venue to do so.

    Curiosity and exploration are hardwired into our basic human nature. We strive to understand and explore the environment around us. From individuals climbing Mt. Everest, to those journeying deep into the Amazon Rainforest, it is our innate desire to discover and be adventurous. It is natural that this desire would eventually turn to areas beyond our planet. In the late 1950’s the escalation of the Cold War led to the space race. It started with the launch of the satellite Sputnik I by Russia, and produced amazing feats such as the United States putting a man on the moon. During the height of the space race, NASA was receiving 4.31 % of the national budget (Office of Management and Budget), and it took only eight years for NASA to reach the

  • The Space Race and NASA

    Michael Collins once proclaimed that, “It’s human nature to stretch, to go, to see, to understand. Exploration is not a choice really; it’s an imperative.” People have always been fascinated by space exploration and it was during the 1950’s that the “race to space” took off. Both Russia and the United States wanted to be the first to travel into space and the first ones to land on the moon. Today, nations are still active in space exploration. This includes NASA (the U.S.), the Russian Federal Space Agency, CNSA (China), JAXA (Japan), ESA (Europe), ISA (Italy), ROSA (Romania), and the Soviet Union. Now, some may argue that the United State’s space program has slowed down or even stopped having interest in space. However, there is a great deal of evidence that shows that NASA is still very much interested in space.
