Natural Selection Essay

The earth itself is an astonishing planet with the fact that life exists on it is an amazing achievement. Evolution is the fact of life and the reason why humans came into existence. Evolution is responsible for all forms of life on earth. The entire natural world, including humans, plants and animals are all directly linked through the evolutionary process. Over the period of time, those species who were best fit to survive remained into existence and those who were unfit got extinct- “survival of the fittest” derived from Charles Darwin evolution theory-The mechanism of natural selection. So just like other existing species, humans have done something right in the

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

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.

There are four parts of natural selection, overproduction, genetic variation, selection, and

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 descendants of the species have been given changes from their ancestors. This is called natural selection. Natural selection is a type of evolution that animals go through when there is a hardship in their natural habitat. Most animals go through natural selection to survive, they can pass it on to their kin.

Our relationship with nature has currently become strictly economic. we tend to don't associate ourselves as a section of nature as a result of we tend to use it for profit. Forests ar abate for the profits of the lumber trade and to form area for placental mammal. Animals that we tend to ar doubtless associated with, that have senses and therefore the ability to socialize ar slaughtered by the billions to feed Associate in Nursing more and more carnivorous population. Resources like oil and food ar all erratically distributed throughout the globe and thus used as a platform for profit. All the whereas the surroundings bears the grunt of our

Natural selection is the evolutionary process by which heritable traits that best enables organisms to survive and reproduce in a particular environment are passed to ensuing generations. Organism within the same species may develop new characteristics based on their environment to ensure their survival. The new genetic development within the species maybe then passed on to their offspring. Those within the species that do not develop a new characteristic to adapt to the altering environment are left prone to disease, deformities, and even death or extinction.

Natural Selection- Natural selection is the way organisms adapt over time so that they have the best chance of survival in their environment. Natural selections selects against unfavorable traits, so that the ones that will be of the most evolutionary help will be more common. There are three different way that natural selection occurs; directional selection, stabilizing selection, and disruptive selection. Directional selection is "a favored trait is at the extreme expression of traits," (Kobari). Stabilizing selection is the "selection against extreme expression of traits" (Kobari). Disruptive selection is when

Humans have endured a lot since they have gotten out of the golden age starting from the last giving tree they had to the destruction of the earth, however nature has been there before Humans and even before the Gods, Nature exist even the chaos that was there before Gaea (Mother earth), or in Hindu myths where Vishnu in his destroyer form, kills all of the other gods and goes to sleep in an egg where there is nothing left but darkness. Whether when nature and humans are harmonious or at odds they will always be intertwined, it is just long after humans have come and gone nature will always be

Natural selection in evolution also involved genetic changes from one generation to another. There are two examples that I found helpful in my quest for understanding evolution through genetic evidence. They include variation and inheritance. In the variation, each and every living organism is a little bit different from the other. (Primate behavior and ecology.,03-07).Each of them is genetically unique. As a result of random changes in the genetic make-up, subsequent living organisms are born with new and quite different traits. This occurs in the processes of mutation and meiosis. (Weiner 01-04). Adaptive radiation occurs whereby closely related species live in different environments, and the process causes variation in the genetic makeup of species from a common ancestor.

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

Charles Darwin broached the theory of natural selection in his book the Origin of Species, which has been considered the basis of evolutionary biology to this day. Natural selection is when populations of a species evolve over the course of many generations. Darwin believed that species were not created separately, but instead, species were derived from one another. In other words, the evolution of species creates many variations among creatures, and this is because all of those species came from a common ancestor, and characteristics changed to increase the species chance of survival.

     As I mentioned before our environment has a great effect on our nature. For example a theory claimed that, the first humans

Artificial selection and natural selection are different forms of the same practice that Charles Darwin observed. Artificial selection is when man controls the breeding for a specific trait just like genetic engineering where scientists alter and clone genes to produce a new trait in an organism. At the same time, natural selection is based on environmental conditions. Natural selection is Darwin’s famous theory stating evolutionary changes that occur through the production of variation in each generation. Organisms that are best suited to their environment
