According to Dictionary.com eugenics is defined as “the study of or belief in the possibility of improving the qualities of the human species or a human population, especially by such means as discouraging reproduction by persons having genetic defects or presumed to have inheritable undesirable traits or encouraging reproduction by persons presumed to have inheritable desirable traits.” What this means is that Eugenics is to believe in improving certain traits or eliminating diseases from people using genetic engineering. Eugenics is morally wrong, how would you like to be born and have to grow up and have to be good at things you don’t even like. You might want to play sports professionally but your parents have chosen for you to have
- The variability contained in the genetic information allows evolution of populations. Evolution; - Is the process by which changes occur in populations of organisms over time. Population – the smallest unit capable of evolving (individual organisms cannot evolve; they are part of the process, but it is the population that evolves). - Survival of a species depends on successful reproduction; not all members of a population can reproduce. Species – group of organisms that can interbreed to produce fertile offspring.
Outline and evaluate evolutionary explanations of human aggression (infidelity and jealousy) [8+16 marks] The evolutionary theory states that a human’s main aims are to survive long enough to pass on their genes, and to ensure that those genes live on in their children. If the desire to achieve these goals is not met, or is threatened; humans can become aggressive. Evolutionary explanations can explain aggression in many ways, including infidelity and jealousy. In both males and females infidelity, whether it is real or imagined, causes jealousy and therefore aggression. The jealousy is seen by evolutionary psychologists as an adaptive response and it is therefore useful.
Misconceptions about Evolution Natural Selection Many People are oblivious to the key elements of how evolution and natural selection play a part in our own world; creating misconceptions of various prospects of survival skills. When we think of survival skills, many unknowingly mishap one of the most influential fundaments of natural selection, which consist of traits that help individuals survive and reproduce in a given environment to survive with constant changes over time; also known to be one basic mechanism of evolution ( “Evolution 101 :Natural Selection”). Understanding natural selection is not as difficult as some may perceive it to be, discoverer Charles Darwin came up with an accessible concept to rationalize the whole progression. In 1859, he published “One the Origins of Spices by Means of Natural Selection” (Park pp45), which explained the natural process of how species come and go through various phenomenon changes and still exist. There are two other selections known as artificial selection, meaning a selection for reproductive success in plants and animals that is directed by humans (Park pp53);and there is sexual selection which acts on an organism’s ability to obtain or successfully copulate with a mate (Evolution 101).
This is less influenced by environment because as adults they their own can make their own choices and decisions. For emotional and social development it is nurture if their partner died that may affect emotional because everyone around will be sad and this will cause they to be upset too. As you get older you may make more friends because you are retried you will have more time to spend with friends with is because of the environment. From older adulthood both nurture and nature have a big impact, but I think nature has a greater impact because of their hair will change colour and they may lose some of their hair too. They may lose their hearing, eye sight, and maybe memory and this happens to everyone
In Michael J. Sandel ‘s account “The Case Against Perfection” he talks about the positives and negatives of genetic engineering, and producing drugs to help the human species. Michael J. Sandel in my opinion agrees and disagrees with my idea of using genetic engineering, new procedures, and new drugs to help improve human life. Michael starts off on how these new ideas can help us out in four areas: muscles, memory, height, and sex selection. In the muscles category he talked about using the new genetic techniques to make muscles stronger. When you’re at old age your muscles tend to get weaker and they start to hurt.
Examine one evolutionary explanation of behavior Before we had the technology to look at genes specifically, a theory was used to explain how we’ve adapted the traits we have today. Darwin’s theory was that those who adapt best to an environment will have a greater chance of surviving, having offspring, and passing their genes to their offspring. As our environment is always changing, we need to adapt our characteristics to survive in that specific environment. It is the whole aspect of adaptation. It is said that those who are better suited for a certain environment will be more like to breed and pass on these genes also known as natural selection.
In the past, high status and resources meant greater opportunities for reproduction with other successful mates, therefore being a celebrity gives lots of chances for reproductive success. Henrich and Gil-White proposed the prestige hypothesis, which argues it is often difficult to establish which specific behaviours lead to success in a famous individual. This means it make sense in evolutionary terms to copy all of the behaviours of a successful individual. Evolutionary explanations are very hard to test scientifically as we cannot go back in time to see if it is true. As such, it is not a truly scientific explanation for the attraction of celebrity.
This often results in a change in the characteristics of an organism. In a given generation the contribution of a mutation will be minimal to a population’s variation, however over an extended time period it will have a significant effect on the phenotypic variation in a population if it better adapts an organism to its environment (Stebbins, 1971). Note that a mutation that causes a dramatic change in an organisms phenotype will not improve the fitness of an organism such as a
Charles Darwin and Sigmund Freud both challenged Enlightenment assumptions about human behavior and the role of reason. The Enlightenment thought humans were superior to animals and should think reasonably. Darwin believed humans evolved over time into what the species is today. It was this concept of evolution that Darwin understood which Enlightenment did not have. Sigmund Freud's id, ego, and super ego theory brought about a new way of thought that challenged the Enlightenment.
