Charles Darwin and Human Evolution in Intelligence Essay

The great and famous Charles Darwin is still remembered today after almost 2 centuries had passed. He was one of the most significant scientists to change how we view this world. Life, as we know it, was changed by Charles Darwin. But I don’t believe that looking at the present will help in any way so I will take back to the past. It is a fact that throughout history people have always believed in some sort of god. Some religions were weak and have come and gone, where others have come and stayed. Many historic wars were fought for a god. So I believe it is safe to say that religion was the most important thing in life for everyday people. Then comes the renaissance, a time of successful new art, science and new ideas. Humans came out of†¦show more content†¦An example of an analogous structure would be the wings on butterflies, bats, and birds. The human appendix is another example. It is no longer used in the human body but it is still there. However this is because we evolved so much that we no longer need to use an appendix to survive. Another important example would be the development of an eye in both mollusks and vertebrates. This example of analogous structures is especially useful because one of most common claims made by religious creationists is that something as complex as an eye couldnt possibly have evolved naturally - they insist that the only possible explanation is a supernatural designer (which is always their god). However if you see the eye of a hawk and the eye of a human they greatly differ. This shows that the eye of the hawk has evolved more due to its environment and its hunting characteristics. On the other hand, the human eye is rarely used to find something a small as a rat from a thousand feet away. The fact that the eye in different species are analogous structures proves that the eye could evolve naturally, but also that it in fact evolved several times, independently, and in different ways every time. The same is true of other analogous structures as well, and this is because certain functions (like being able to see) are just so useful that its certain they will evolve eventually. No supernatural beings, whether gods or not,Show MoreRelatedCharles Darwin, The Father Of Evolution835 Words   |  4 Pagesdual credit 14 December 2015 Evolution Charles Darwin, the father of evolution, wisely stated, â€Å"It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.† This statement directly reflects my opinion on the theory of evolution and that of Charles Darwin.

Lord of the Flies by Sir William Golding Free Essays

Lord of the Flies was the first novel published by Sir William Golding. Although Golding had published an anthology of poems nearly two decades before writing Lord of the Flies, this novel was his first extensive narrative work and is informed by his scientific training an academic background. In many ways Lord of the Flies is a hypothetical treatment of particular scientific concerns. We will write a custom essay sample on Lord of the Flies by Sir William Golding or any similar topic only for you Order Now It places a group of young English boys on a deserted island where they must develop their own society, in essence constructing a sociological experiment in which these boys must develop without any societal influences to shape them. In fact the beginning chapters of the novel parallel assumptions about human evolution, as the characters â€Å"discover† fire and form levels of political authority. However, what concerns Golding in Lord of the Flies is the nature of evil as demonstrated by the boys on the island. He concludes that the evil actions that the boys commit are inherent in human nature and can only be controlled by societal mores and rationality, as exemplified by the characters Piggy and Ralph. Although the novel does not adhere to themes particular to one religious tradition, in Lord of the Flies Golding draws upon a great deal of religious symbolism updated to conform to more contemporary ideas of human psychology. The title character,’ the pig’s head that Simon dubs the â€Å"lord of the flies† is a translation of the Hebrew word Ba’alzevuv, or its Greek equivalent Beelzebub. For Golding, this devil comes from within the human psyche rather than acting as an external force, as implied by Judeo-Christian teachings. Golding employs this religious reference in more Freudian terms. The devil that is the â€Å"lord of the flies† represents the Freudian conception of the Id, the driving amoral force that works solely to ensure its own survival. The â€Å"lord of the flies† directly confronts the most spiritually motivated character of the novel, Simon, who functions as a prophet-martyr for the other boys. Lord of the Flies is firmly rooted in the sociopolitical concerns of its era. Published during the first decade of the Cold War, the novel contains obvious parallels to the struggle between liberal democracy and totalitarianism. Ralph represents the liberal tradition, while Jack, before he succumbs to total anarchism, can be interpreted as representing military dictatorship. In its structure as an adventure the novel further resembles the science-fiction genre that reemerged as a popular form of literature during the fifties. Symbolism played an important part in the development of story. This narrative technique is used to give significance to certain people or objects, which represent some other figure. Piggy and glasses represents clear-sightedness, intelligence. Their state represents the status of social order. Ralph, the Conch represents democracy and order. Simon represents pure goodness or Christ figure. Roger represents evils or Satan. Jack represents savagery and anarchy. The island represents the world where people live. The scar represents man’s destruction or destructive forces. The beast represents the evil residing within everyone or   the dark side of human nature. The Lord of the Flies represents the Devil and great danger or evil. There are many other aspects in the story that may be considered symbolism, but the several that I mentioned are probably the most significant. Another good example of symbolism is the shape of the island. The boat shape of the island is an ancient symbol of civilization. The water current around the island seems to be â€Å"flowing backwards,† giving the subtle impression that civilization may be going backwards for the island or its inhabitants. William Golding presented numerous themes and basic ideas that give the reader something to think about. One of the most basic and obvious themes is that society holds everyone together, and without these conditions, our ideals, values, and the basics of right and wrong are lost. Without society’s rigid rules, anarchy and savagery can come to light. Golding is also showing that morals come directly from our surroundings, and if there is no civilization around us, we will lose these values. Other characteristics of human beings that he showed in the book are that people will abuse power when it’s not earned. When given a chance, people often take advantage or degrade others to improve their own security. The author also showed that you can only cover up inner savagery so long before it breaks out, given the right situation. Just like what happened to Jack. He also showed in the book that it’s better to examine the consequences of a decision before you make it than to discover them afterward. Another theme in the book that I have observed is that the fear of the unknown can be a powerful force, which can turn you to either insight or hysteria. Just like what happened when they fear the unknown figure that they saw in the island which led them to murder Simon. I agree with the author’s theories on the basic nature of human beings. Without the values or morals being taught in our society and the basic knowledge of good and evil people will have a tendency to become savage or evil because it is part of the human nature. It goes back to the fall of the first man named Adam. After the fall, sin became a part of the human nature. Without the teachings of good values and morals, savagery will manifest in people.    How to cite Lord of the Flies by Sir William Golding, Essay examples

Describe physical, intellectual, emotional and social development for each of the life stages Essay Example For Students

Describe physical, intellectual, emotional and social development for each of the life stages Essay Describe physical, intellectual, emotional and social development for each of the life stages Conception and Pregnancy All human life begins from conception. Majority of the time, women wont know the exact day when they got pregnant. Your doctor will count the start of your pregnancy from the first day of your last menstrual period. Thats about two weeks ahead of when conception actually occurs. Each month inside your ovaries, a group of eggs starts to grow. Eventually one of the eggs erupts from the follicle and this is known as ovulation. It usually happens about two weeks before your next period. A hormone is released that helps thicken the lining of your uterus, getting it ready for the egg. After the egg is released, it moves into the fallopian tube. When a sperm does make its way into the Fallopian tube and burrow into the egg, it fertilises the egg. The egg changes so that no other sperm can get in. The egg stays in the Fallopian tube for about three to four days, but within 24 hours of being fertilised it starts dividing very fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. The developing collection of cells is now called an embryo and is attached to the wall of the uterus by a placenta. Chemicals are released to prevent the women having another menstrual period. By 8 weeks, the embryo had grown between approximately 3 and 4cm, has a recognisable heartbeat and the beginnings of eyes, ears and a mouth. At this stage, it’s known as a foetus. During the remaining 7 months, all the organs continue to develop and by 20 weeks, the foetus will have reached about half its length at birth and by 32 weeks, it will be about half its birth weight. Only about half fertilised eggs develop to become babies and is many eggs are lost without the women ever knowing she was pregnant. Birth and Infancy: 0 – 3 years Birth is the end point of pregnancy and results in the expulsion of newborn from the pregnant womans uterus. Birth has three stages of labour: the cervixs shortening and dilation, the descent and birth of the infant, and the expulsion of the placenta. Birth can also be done via caesarean section which is the removal of the newborn through a surgical incision in the abdomen. The newborn baby, also referred to as a neonate, must consume easily digestible food such as the mother’s milk within the first few months in order to grow. When babies are born, their brains are not fully developed however they can hear sounds, tell differences in the taste of things and identify the smell of their mother or main carer. This is due to infants being born with various temporary and primitive reflexes. The primitive reflexes consists of: Rooting reflex: this is when the newborn baby turns their head towards any touch on the cheek and this helps them to get the nipple into their mouth to feed. Grasp reflex: If you place your finger in the palm of the baby, they will grasp your finger tightly. When the baby is startled i. e. by loud noises, they will throw their arms outwards, arching their back and straightening their legs. This is called the startle reflex. If the baby is held upright, they will attempt to move their feet as if they are walking. This is called the walking reflex. Regarding physical development, the first year is the period of rapid physical growth. A normal baby doubles its birth weight in six months and triples it in a year. During that time, there is great expansion of the head and chest, allowing development of the brain, heart, and lungs. The bones, which are relatively soft at birth, begin to harden and soft parts of the newborn skull, begin to calcify, the small one at the back of the head at about 3 months, the larger one in front at varying ages up to 18 months. Brain weight also increases rapidly during infancy: by the end of the second year, the brain has already reached 75% of its adult weight. The babies’ physical features will also noticeably change i. e. the face shape, hair length etc. Babies motor skills develop as they get older from hand-eye coordination, passing objects from hand to hand to rolling over, supported walking and free walking by 18 months +. They later on learn to run and climb stairs. Babies prefer the sound of humans interacting to other sounds and from this, they quickly learn to recognise and identify their mother’s voice. Babies form their first relationship through emotional attachments with their mother or main carer. The first year of a baby’s life is a period of incredible growth, and a baby’s brain goes through critical periods during which stimulation is needed for proper development. During the babies first years, visual stimuli or verbal language is necessary for areas of the brain to grow and without this growth, a child’s vision or speaking abilities might be impaired. Infants tend to have different cries for hunger or pain, as well as making other noises. These abilities show your child is gaining communication and pre-language skills. Infants from birth to 6 months will forget about objects they cannot see however they begin to explore objects they can see and grab by putting them in their mouths. They will also follow moving objects with their eyes and look around at nearby objects. Infants in this stage will turn to look at a source of sound. These developmental milestones show a baby’s brain is developing and they are gaining new skills. From 7 to 12 months, infants also learn the idea of cause and effect, and they might repeat an action that causes a certain reaction i. e. they will shake a rattle and listen to its noise. While younger infants will forget about objects you hide, older infants will look for things they see you hide. Frees William Golding's Lord of the Flies Fr EssayDuring adolescence, the developing teenager acquires the ability to think systematically about all logical relationships within a problem. The transition from concrete thinking to formal logical operations occurs over time. Each adolescent progresses at varying rates in developing on their ability to think in more complex ways. Each adolescent develops their own view of the world, some may be able to apply logical operations to school work long before they are able to apply them to personal dilemmas. When emotional issues arise, they often interfere with an adolescents ability to think in more complex ways. The ability to consider possibilities, as well as facts, may influence decision making, in either positive or negative ways. During early adolescence, the use of more complex thinking is focused on personal decision making in school and home environments such as beginning to demonstrate use of formal logical operations in schoolwork and to question authority and society standards. Middle adolescence often expands to include more philosophical and futuristic concerns such as questioning and analysing more extensively as well as thinking about and beginning to form their own code of ethics. During late adolescence, complex thinking processes are used to focus on less self-centred concepts as well as personal decision making i. e. having increased thoughts about more global concepts such as justice, history, politics, and patriotism and developing idealistic views on specific topics or concerns. They may also begin to focus thinking on making career decisions and emerging role in adult society. Adulthood: 19 – 65 years and Older Adults: 65+ years Young adults are often at their peak of their physical performance between the ages of 18 and 28 years of age. Above this age ranges, adults will tend to lose some strength however this goes highly unnoticed unless they are in competitive sports. There are numerous physical changes relating to age and some of the more noticeable ones would be hair loss which is more common in men. Adults near the higher end of the age range may begin to wear reading glasses as eyesight is known to deteriorate with age as well as finding they are unable to hear higher pitched noises. Women are most fertile in their late teens and early twenties, the risk of miscarriage and pregnancy complications rising with age. Between the ages of 45 and 55, fertility reduces and then comes to an end with most known physical change in women, the menopause. This involves: The gradual ending of menstruation and the reduction in number of eggs in the ovaries Increased production of hormones which tries to stimulate egg production and can cause irritability, hot flushes and night sweats Reduction in production of sex hormones causing shrinkage of sexual organs and can also cause reduction in sexual interest Associated problems i. e. steoporosis which can be caused by the reduced production of sex hormones Older adults are more likely to gain weight as they are no longer as physically active as they once were. The weight gain is mainly caused by adults eating the same amount of food they did as they were much younger but they have become much less active so will not burn it off as they once did. Approaching and entering into older adulthood, individuals are more at risk of developing disease and disabilities. Ot her physical signs of ageing would be the sagging of skin and appearance of wrinkles on certain regions of the face. Socially, during early adulthood, friendship networks continue to remain highly important to individuals. For many in early adulthood, a main priority is forming adult sexual relationships and finding work or establishing a career. The commitment of marriage and becoming parents is a representation of major social development in their lives. Socialising and individuals social activities may be reduces due to time pressures however this is mainly in the age region of forties and fifties. More mature adults will manage to balance their priorities and commitments such as looking after family members, work, children etc. as well as being able to fit in their social activities. It’s important that adults maintain a social life in order to keep them simulated and allow them to relate to others in the same life stage as them. Those at the ages of 60 – 65+ may have retired and will now use their free time to spend and build on their relationships with their family and friends rather than increase their social network. During their free time, they may also emerge themselves into new hobbies and interests to keep themselves busy and active. Intellectually, individuals within this age range During early adulthood, individuals are learning to cope with the emotional attachment to a sexual partner and to do so, they may have to learn to compromise and change themselves. This would involve not being too self-centred or defensive and not becoming emotionally isolated. Young adults will be more into searching for individuals to get involved with intimately and finding a person they would consider settling down with. When in relationship, many adults may then change themselves in certain ways to express their emotions for their partner and accommodate them in their lives. Getting older, adults may face the risk of emotional ‘stagnation’ when they lose interest in social issues. Along the journey into adulthood, many may waver at the commitment when it comes to events like marriage and starting a family. This is due to them being hesitant as it’s emotionally, a significant attachment and development. Into older adulthood, individuals need to develop a secure sense of self as this enables them to cope with and come to terms with the physical changes associated with old age. As well as this, they may begin to think and wonder about their lifetime achievements and how they’ve lived out their lives. This is due to the drawing closer of death. For some individuals who cannot make sense of their life may experience emotional despair.
