Altruists attract and origins of mating behavior Essay In the experiment study altruists attract researchers concluded that people tend to corporate with the more attractive members of the opposite sex. Besides, as more one member of opposite sex is showing corporation, the more attractive it may seem to other member of the opposite sex. No doubt, altruistic behavior is beneficial in both genders which are in the long-term relationships because they share the same resources or care about their children. Research shows that people who are corporative are viewed by others as more attractive and kind and these are the values which people count for when are looking for mating partners. For example, males tend to give more money to women beggars than to the same sex beggars-males. Second article talked about origins of mating and how people choose partners when it comes to mating. Charles Darwin was the first who proposed the theory of sexual selection, emphasizing that mating behavior can be explained by evolutionary change; preferences for a mate and competition for a mate. Humans never choose mating partners just by coincidence; they tend to use strategies in order to find the most appropriate mate. Also, our ancestors used strategies for mating, they chose to mate with the opposite sex members who were reproductive in order to pass on genes to the next generations. For instance, females choose their mates who are economically independent, who will take care of them and their children, and who would devote their time to family. These both strategies can be both referred to our ancestors and our time scale. Author of this article compare women with weaverbirds which also prefer man with rich and fruitful nests. However, the most difficult decisions for humans in selecting a mate is to distinguish and indentify what kind of relationship are they looking for; short term or long term relationship. Even when it comes to animal mating, the stronger and larger ones are the more chances in finding an appropriate mate. Therefore, the weaker ones ten to fail in finding a mate and they become extinct. No doubt, keeping a mate is another important thing for the people who are seeking a long term relationship. Some people tend to be by nature more jealous than others. Therefore, sexual jealously can elicit either vigilance or cause violence between couples. Finally, it is not in human nature to date just with one person for an entire lifetime. Humans often brake up or split with other member of sex, due to the conflicts such as one may feel unsatisfy being in a particular relationship, cheating or other reasons. All over the world humans are failing for the divorce. It is not only seen in Western world. When people brake up or split they tend to enter again the mating market. But reentering again and starting everything from new can cause other problems. For example, women having children from previous relationship may have difficulty to finding a new mate. Besides, ages plays a big role in finding a mate.

Mya Angelou :: Essays Papers

Mya Angelou Toni Morrison, the first black woman to receive Nobel Prize in Literature, was born Chloe Anthony Wofford on February 18, 1931 in Lorain, Ohio, U.S.A. She was the second of four children of George Wofford, a shipyard welder and Ramah Willis Wofford. Her parents moved to Ohio from the South to escape racism and to find better opportunities in the North. Her father was a hardworking and dignified man. While the children were growing up, he worked three jobs at the same time for almost 17 years. He took a great deal of pride in the quality of his work, so that each time he welded a perfect seam he'd also weld his name onto the side of the ship. He also made sure to be well-dressed, even during the Depression. Her mother was a church-going woman and she sang in the choir. At home, Chloe heard many songs and tales of Southern black folklore. The Woffords were proud of their heritage. Lorain was a small industrial town populated with immigrant Europeans, Mexicans and Southern blacks who lived next to each other. Chloe attended an integrated school. In her first grade, she was the only black student in her class and the only one who could read. She was friends with many of her white schoolmates and did not encounter discrimination until she started dating. She hoped one day to become a dancer like her favorite ballerina, Maria Tallchief, and she also loved to read. Her early favorites were the Russian writers Tolstoy and Dostoyevski, French author Gustave Flaubert and English novelist Jane Austen. She was an excellent student and she graduated with honors from Lorain High School in 1949. Chloe Wofford then attended the prestigious Howard University in Washington, D.C., where she majored in English with a minor in classics. Since many people couldn't pronounce her first name correctly, she changed it to Toni, a shortened version of her middle name. She joined a repertory company, the Howard University Players, with whom she made several tours of the South. She saw firsthand the life of the blacks there, the life her parents had escaped by moving north. Toni Wofford graduated from Howard University in 1953 with a B.A. in English. She then attended Cornell University in Ithaca, New York, and received a master's degree in 1955. After graduating, Toni was offered a job at Texas Southern University in Houston, where she taught introductory English.

The Kite Runner/Life of Pi: the Foil

The Kite Runner/Life of Pi: The Foil In both The Kite Runner and Life of Pi, the relationship between the major character and a minor character—the foil—help to highlight the main character’s qualities, illuminating his traits to be seen in an extraordinary, nonstandard way. In The Kite Runner, Khaled Hosseini creates Hassan as the foil for Amir. Hassan’s character, as perfect as he is, causes Amir to pale in comparison, something that Amir channels throughout his life, governing his actions.Similarly, Yann Martel employs Richard Parker as the foil for Pi in Life of Pi. The strength and ferocity of the tiger emphasizes Pi’s hopelessness and fear. Pi utilizes these emotions to fight and continue living. In both novels, the foil character underlines the main protagonist’s characteristics and provokes certain feelings that ultimately determine his fate. In The Kite Runner, Hassan is Amir’s half-brother, best friend, and servant. His chara cter is nearly perfect—loyal, courageous, caring, kind, and selfless. He has no evil qualities.When compared to Hassan, Amir’s value and positive qualities fall flat and are seen as insignificant and mediocre. Even more, his bad features are amplified and made more prominent. Amir cannot live up to Hassan’s goodness. This inadequateness is put into words and exemplified through Baba, who declares that, â€Å"If I hadn’t seen the doctor pull [Amir] out of my wife with my own eyes, I’d never believe he’s my son† (Hosseini 23). Baba often treated Amir and Hassan equally, which was unusual because the Hazara was essentially their servant.If Amir asked for a big and fancy kite, Baba would buy it for him—but then he would buy it for Hassan as well (Hosseini 51). These displays of affection were later explained in that Baba was actually Hassan’s real father, but the effect they had had on Amir stuck. Amir was always desperately vying for his father’s love and approval. The fondness Baba treated Hassan with vexed and aggravated him. Without the knowledge of Hassan’s true parentage, Amir felt many flashes of jealousy and frustration—emotions that, compared with his own brother’s understanding and humility, projects him as criminal.The most prominent situation that highlights Amir’s character is when he witnesses Hassan being raped. The event leading up to the incident is of Hassan running after the final kite—just for Amir. He finds it, only to be cornered by Assef who demands the kite as retribution for the â€Å"rude manners† he showed him during and earlier incident (Hosseini 71). Hassan refuses, retorting back, â€Å"Amir agha won the tournament and I ran this kite for him. I ran it fairly. This is his kite† (Hosseini 72). He is assaulted in reply.Here, Hassan’s traits of extraordinary loyalty and courageousness are displayed; however, switc h the scope to Amir and the qualities revealed are the exact opposite. Amir witnessed the raping of his best friend and did nothing. He was afraid of getting hurt, afraid of losing Baba’s newly earned affections and simply ran away (Hosseini 77). When compared to Hassan, Amir’s qualities of selfishness and cowardice are highlighted and intensified. From the presence of Hassan, Amir’s selfishness and cowardice, in addition to his desire to be â€Å"good enough†, are not only emphasized, but acknowledged by Amir himself.These are the traits that ultimately drive him throughout his life. The recognition of the evil in himself coupled with his will to do good lead him to search for redemption—one of the main themes of the novel. With the immense guilt over Hassan’s rape pushing him forward, Amir lives his life stiffly until taking the move to America where he starts a new morally upright life, where he helps his father and marries a good woman, and then finally completely redeeming himself through returning to Afghanistan and saving Sohrab from Assef.By establishing Hassan as a foil character for Amir, Hosseini creates a domino effect in which his main character discovers himself, realizes he dislikes what he finds, and fights his way towards the â€Å"way to be good again†Ã¢â‚¬â€redemption. In Life of Pi, Pi’s fellow passenger throughout most of his time at sea is Richard Parker, a 450-pound Royal Bengal tiger. The wild, aggressive tiger initially places the sensitive, intelligent Pi in an immense state of fear. Pi is overwhelmed by terror over an animal known for its ferocity and power, an animal he’s seen viciously attack and devour a live goat (Martel 35).Richard Parker scares him witless. His main focus, then, is to survive this creature. Richard Parker’s intimidating nature at first reveals Pi’s initial sense of surrender and loss of faith and general humanity. â€Å"With a tiger on board, my life was over† (Martel 135). As he accepts the presence of the tiger, however, he becomes determined. Richard Parker’s animalistic nature rubbed off on Pi. In place of his slight loss of humanity arises a sense of instinctual will to live. â€Å"I will not die. I refuse it.I will make it through this nightmare† (Martel 148). He hatches â€Å"several plans to get rid of [Richard Parker]† and ultimately decides to tame him (Martel 157). The decision gives Pi a sense of purpose, a distraction from the hopelessness of his situation—stranded in the middle of ocean, completely and utterly alone. If he killed Richard Parker, Pi acknowledges that he â€Å"would be left alone with despair, a foe even more formidable than a tiger† (Martel 164). He declares, â€Å"It was Richard Parker who calmed me down.It is the irony of this story that the one who scared me witless to start with was the very same who brought me peace, purpose, I dare sa y even wholeness† (Martel 162). In the end, Pi was able to survive because of Richard Parker. He kept Pi from â€Å"thinking too much about [his] family and [his] tragic circumstances. He pushed [him] to go on living† (Martel 164). Richard Parker’s role as the foil character to Pi is characterized by the fear and determination that the tiger incites in Pi. Compared to the magnificent animal, Pi becomes a defenseless, hopeless human.But, motivated by the feeling of weakness, Pi’s inner animalistic nature reveals itself. Through the daunting presence of Richard Parker, Pi discovered within himself that he had â€Å"a fierce will to live† (Martel 148). Richard Parker’s, the foil character’s, relationship with Pi personifies one of the major themes of the novel: the will to live. The entire novel is centered on Pi’s struggle to survive in this seemingly impossible, dangerous, and depressing situation. Pi’s instinct to survive is represented by the tiger itself. The qualities of Richard Parker, of the animalistic characteristics, were crucial to his survival.Despite some hesitation, Pi ultimately learns to embrace Richard Parker. He learns to embrace that fierce will to live, learns to fight for survival and, in the end, makes it out alive. The Kite Runner and Life of Pi were both written with a foil character. In both novels, the character motivated and provoked the main protagonist into discovering himself. The fates of both main characters were determined by the ways their foil affected them. This relation between two characters not only significantly establishes the characters themselves, but illuminates the meaning of the work.
