Evolution By Natural Selection Essay

Evolution is a change in the characteristic of living organism through time. Modern synthesis, one of the greatest intellectual achievements of biology, could explain how mutations and natural selection could produced large-scale evolutionary change. There are 4 mechanisms for evolution to occur; mutation, gene flow, genetic drift and natural selection.
Although, there are a number of misconceptions about evolution; it does not explain the origins of life, it is not progressive, natural selection is not about the survival of the fittest individuals in a population, humans are not currently evolving, it does not make organism better designed nor does it gives organism what they need to survive. This essay will describe further, 3 common misconceptions

Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical

There are five processes to microevolution. There is gene flow, mutation, natural selection, genetic drift, and recombination. Gene flow is when genes amongst a population are exchanged. It affects microevolution because it is a change or movement in certain populations that lead to a different mixture of alleles. Another processes of microevolution are mutations. A mutation is any change in an organism’s DNA. It is an important factor in microevolution because it is the reason for the development of new genes. Although it is very rare, when mutations are mixed with the act of natural selection, evolution occurs faster. Natural selection is a process where organisms are able to adapt to their surrounding environment and survive. The organisms

Natural selection involves the adaptation of a species to better survive in their designated environment. When organisms reproduce, they pass down their DNA to their offspring. For example, a child that is tall is the result of their parent being tall as well. Parents pass down traits to their children. When it comes to survival, some organisms are better at it than others based on the traits that they have acquired. Some organisms can camouflage from predators while members of the same species do not obtain that same trait. With that in mind, the ones that can camouflage will most likely survive in certain environments and they will then pass on that trait when they reproduce. Since these traits are advantageous, they are passed on to more and more offspring through time and it will eventually overcome any original traits that species first started out with. It’s kind of like the current state of sexual misconduct in Hollywood. We have our directors, actors, agents, and so forth. However, as time goes on, some do not survive in the business based on their inherently evil traits and they get weeded out just like some species in the wild. As generations pass, these organisms have then adapted to fit the environment and better survive based on their inherited traits.

Define evolution? A slow change of something into better form. The word evolution means change, and the process of evolution reflects this definition as it applies to populations of organisms. Biological populations are groups of individuals of the same species that are sub-divided from other populations by geography and are somewhat independent of other groups. Biological evolution, then, is a change in the characteristics of a biological population that occurs over the course of generations. The changes in populations that are considered evolutionary are those that are inherited via genes. Changes that may take place in populations due only to short-term changes in their environment are not

Natural selection is the process by which organisms better adapted to their environment survive and produce more offspring. It’s believed to be the main process that brings about evolution. Natural selection will over time remove the deleterious gene as they have a negative effect for the population and are therefore not going to survive or produce offspring.

The process of natural selection is the reason evolution occurs, which also supports the evidences of traits that occur. And for natural selection to take effect, three elements are necessary, and variation is two of these three elements. This specific element expresses that with consideration to specific traits, individual organisms in a population are varied from one another, such as differing from reproduction, fitness, and survival. These traits can be advantages or disadvantages. For instance, an advantage can be having a higher reproductive rates which is a good quality for survival. And in the second element relating to variation, it concurs that variation is passed on from parent to child. So if the parent has traits that has higher reproduction and survival, it passed on to their offspring. And the environment itself is the critical mechanism.The environment impacts which traits

Evolution involving various stages and one of them was natural selection. There are numerous examples that are evidence enough of the process of evolution by natural selection. Out of those various examples, I found two of them useful in my comprehension of how natural selection works. These are a creation of pressure by limited resources and adaptation. During the evolution process by natural selection, the limited amount of resources that existed during that time greatly contributed to the selection pressure experienced by the living organisms. This was as a result of the changes in the habitats, climate as well as the increase in the population of the organisms. As population increased, the

Natural selection; Darwin’s natural selection has by individuals better adapted to their environment with survival and reproductive success. (Than, 2005) Variation is an example of Natural Selection. Variation shows that the outcome of an organism changes. The outcome will be found by existing genetics and there will not be any invented characteristics. As a result of variation varieties that have long tails or shorter tails may appear in certain species’ gene pool. (____________). With that being said though that is not saying that variations can change a bird into a reptile. Heredity is another way natural selection plays a part in evolution. Heredity is the passing on a physical or mental characteristic genetically from one generation to another. Humans are an example of heredity, by children get genes from their parents. When you look at the genes from both your parents, they are not the same. Parents genes change over time, to show this look at a family with two kids, they I’ll not have the exact same genes, because the kid 's genes will have some of the different parental genes but some will be the same. Which is why the two kids can look similar. People that do not believe in evolution would use the argument

Although Ronald Aylmer Fisher isn’t a relatively famous or well- known statistician, he is still considered to be amongst the greatest twentieth century scientists. Ronald Fisher found success through his carefully researched statistics by unifying concepts of natural selection and sexual selection to discover ways to help improve the human race.

Specific forces drive evolution and alter populations over the course of many generations. Different characteristics are inherited when a modification occurs in a species. Present genes within a population controls the characteristics, which determine the allele frequencies. Evolution occurs in a population of interbreeding that involves multiple members. To drive evolution, there are five forces: Natural selection, Migration, Mutation, Nonrandom mating, and Genetic drift.

I have grown up being told that evolution is not true and I should never believe in it because it goes against Gods word. But now after many years, I have decided that Evolution is not that bad of an Idea, that is if you believe that God used Evolution as his way to create all of the animals. For example, in Genesis 3:14, after the Serpent deceives man and God says to the serpent “Because you have done this, cursed are you above all livestock and above all beasts of the field; on your belly, you shall go, and dust you shall eat all the days of your life." This is an example of evolution Serpents losing their limbs and becoming snakes. In like manner, Microevolution is another illustration of Theistic Evolution. Microevolution is shown by Sparrows,

The theory of evolution had existed for much longer than since 1859, however, it was introduced and really accelerated in society when Charles Darwin's The Origin of Species was first published that year. His theory can be found in the English dictionary as "the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth."

The Theory of Evolution by Natural Selection, originally formulated by Charles Darwin in 1858, is the manner in which organisms change over time as a product of specific changes in hereditary physical or behavioral traits. This process provides the organism adaptations that assist and increase the chance of survival in the environment. (http://www.livescience.com/474-controversy-evolution-works.html) Today we can partially thank our existence to natural selection. “Survival of the fittest” is how organisms adapt and survive to the ever-changing environmental conditions, and those “fittest” survive.

GMO stands for Genetically Modified Organism, which is the process of extracting genes from one species into another unrelated species. The process of transferring DNA from two distinct species is through genetic engineering. This displays the new traits of the first donor, which will be part of the genetic make up of the recipient organism. GMO is different from cross breeding or hybridization. Scientists developed GM plants by introducing genes that kill insects and protect crops against viruses. Many of these GM plants require less water so that they are able to grow in areas where water is scarce. The benefit of GMOs help crops grows and ripens faster so that farmers are able to grow more crops throughout the year. On the other hand, GMOs may be harmful to humans if they are not washed and cleaned properly before eating. GMOs include high risk of allergens, toxins, and other unknown side effects that are harmful.
