Organisms That Have Gone Through Natural Selection

Animals fight for survival daily, and sometimes their lives depend on their ability to adapt with their surrounding environments. Natural Selection is the process in which individuals have certain traits that allow

Natural selection is one of the main methods in which speciation occurs through the following steps: • Within a population of one species there is genetic diversity, which is called variation. • Due to the natural variation some individuals will be fitter than others. • Fitter individuals

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.

Evolution is the process of biological change by which descendants come to differ from their ancestors. Natural Selection is when an individual with the best trait survive and breed in more population. Larger populations of organisms with the desired traits will then occur and organisms will evolve. The four principles of Natural Selection are variation, over production, adaptation, and descent with modification. Charles Darwin, an English naturalist and geologist saw two major trends within organisms which were variation and adaptation. Variations are differences in individuals’ physical traits compared to other individuals. In the Galapagos Islands Darwin noticed that finches had different beak sizes and shapes. Darwin then concluded that finches with thicker beaks lived in areas where nuts were the main food source and finches with smaller beaks tended to live in areas where insects were the main food source. Adaptation are features that allow an organism to better survive in their environment. There has been many adaptations in animals but one of the best has been living in groups because animals can then “help each other find food, defend against predators and care for their young” (animalpanet, n.d.). Overproduction is when organisms produce more offspring than the environment can support. Darwin stated that all animals over produce since offspring can reach reproduction age and have offspring of their own. For example, “even a slow breeder

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.

According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.

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

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

The reason for this is because a lot of organism that are around today were closely related a one point ("Comparative Anatomy."Pg.1). Sometimes these similarities are conscious. A good example of anatomy that are humans and primates and also crocodiles and alligators ("Comparative Anatomy."Pg.1). Even species that are far off even humming birds and whales. When looking at these different species you see the natural selection happening in each of these by how their anatomy gets better suited for their environment ("Comparative

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

Natural selection is the process where organisms that have more advantageous adaptions that benefit its survival in its environment then breed and produce offspring with similar traits that then have a greater chance of survival. For natural selection to occur there are essential elements that are required; variation, heritability and excess production. For the formation of a new species there must be variation within a species so that some may have slightly better adaptions to the climate, diseases or other survival traits like better camouflage. The organisms that possess these adaptions are sometimes called more fit; this is called ‘survival of the fittest’. The ‘fitter’ organisms will then reproduce and their offspring will inherit the

Evolution refers to change over time as species modifies and separate to produce several offspring species.

Evolution is “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,” "Google." Google. Google, n.d. Web. 11 Apr. 2015. Evolution is the reason there is change in the genetic makeup of a population, the reason organisms are linked by common ancestors, and evolution is still happening today because of the constant change in environment. This paper focuses on these subjects within evolution and will explore all areas of the process of evolution that creates diversity and unity in life.

Charles Darwin's theory of evolution centres on the idea that species compete to survive, and favorable characteristics are passed on from one generation to the next. Darwin said that evolution took place by a process of natural selection or survival of the fittest. This meant that the animals and plants best suited to their surroundings survived and were able to pass on their genes to their offspring. The ones that weren't best suited died off and didn't get the chance to reproduce.

Evolution is the alteration in the physical characteristics of a species over several generations and depend on the process of natural selection. Evolution explains that as species develop they ultimately reach ideal population levels. As species advance, superior species eliminate inferior species basically making it survival of the fittest. The weak and inferior members
