Natural Selection Essay

803 Words4 Pages

Natural selection is the bases for understanding how species change overtime. It is the adaption of an organism to its environment in order to survive and reproduce. According to Darwin’s theory natural selection is “survival of the fittest” which means only the fastest, strongest and fittest among the group survives for example the strongest and fastest Panthera tigriss (tiger) in the region survives and the slow and weak Panthera tigriss suffers finding food. Natural selection is directly connected to evolution as evolution mainly takes place because of natural selection. When natural selection takes place mutation in species also take place and this causes evolution. There are four factors which are necessary for natural selection to take …show more content…

For example we find different types of elephants like African elephants, Asian elephants and many more types of elephants. These are all variations of elephants. The elephants living in Africa (Loxodonta africana) live in a different climate and environment than the elephants living in Asia (Elephas maximus) and this cause in variation in the appearance of the elephants. Increased variations of traits in a population actually increases the chances of survival as even if a part of the population is wiped out there are still some individuals with the same traits to continue the species by reproducing and …show more content…

The traits they have will be passed down to the next generation after reproduction and the species as a whole will become stronger as the individuals are not suitable for the climate will not reproduce. Therefore, there will only be strong individuals in the coming generation. More individuals will have the traits and will survive till the environmental conditions are beneficial to the individuals. For example a generation of Panthera tigriss has all the beneficial traits and they are passed down to the next generation but the climate is not suitable for the traits passed down then the generation will not survive. This is the purpose of Natural Selection. The tool for evolution and formation of new species is dependent upon these aspects to make it

Natural Selection: Unraveling The Origins Controversy

302 Words | 2 Pages

Natural selection is organisms with traits that are best suited to their environment and are more likely to survive and reproduce. As stated in chapter 5 of Unraveling the Origins Controversy, “Natural selection is deemed the primary mechanism of non-random changes in the number of particular traits in a population” (David A. DeWitt, 2007). Some of the factors that limit natural selection are traits that are not heritable. Some examples are learned behaviors; diet induced traits, and behaviorally induced traits.

Predator-Prey Lab Report

1347 Words | 6 Pages

Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey

The survival and reproduction acts naturally in a certain population. For natural selection, polar bear takes as an example for it can adapt a certain environment. Polar bears have brown and white colored fur which lives differently for the code of their own survival. On the other hand, artificial selection has the selection of natural variations in a population wherein the survival and reproduction is driven

In nature, there are a variety of organisms within the same species who have better-suited adaptations to their environment while some do not. The finches that Darwin studied in the Galápagos Islands of Ecuador, for example, had different physical traits that suited them specifically for their environment, the resources that were available; consequently, the finches who do not have the necessary adaptations die off eventually, unable to reproduce a new generation. With additional research and studies, Darwin formalized this theory on the basis of evolution: “a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less-improved forms.” (Darwin XIV). When a certain species produces too much offspring, they will all fight for the same food or resource that may not be in an ample supply.

Comparing Darwin's Theory Of Biological Evolution And Natural Selection

394 Words | 2 Pages

Since Darwin first suggest his concepts about biological evolution and natural selection various lines of research from many different branches of science have produced evidence supporting Darwin’s belief that biological evolution arises partly due to natural selection. The environment selects certain species because of advantageous characteristic and ability to adapt to the environment in compared to other species. Fossil record illustrates this through old rocks animal remains showing simple to complex evolving. One area is comparative anatomy, which has shown similarities in structures of different living organisms, such as the skeletons of humans, bats cats, and bats. Even though these species live in different climax and environment

Evolution By Natural Selection: One Of The Best Supported Theories In Science

212 Words | 1 Pages

Evolution by natural selection is one of the best supported theories in science. It is the process by which species change over time as a result of changes in physical and behavioral traits. Changes that allow a species to better adapt to its environment, help it survive, and have more offspring(sexual selection). Natural selection can change a species in ways, causing a population to change color or size over several generations and create entirely new species. Population genetics is the study of populations of a species change genetically over time, leading to a species evolving.

The Pros And Cons Of Natural Selection

918 Words | 4 Pages

This process is known as natural selection, which explains how Charles Darwin’s theory of evolution can occur. Natural selection is an important component of evolution. It occurs when some members of a population are better fit for survival and proliferation than others in that population. The environment in which organisms live plays a large part in natural selection as well.

Characteristic Determination: What´s Natural Selection?

752 Words | 4 Pages

Natural Selection Characteristic determination is that it is the system by which a living being that is most appropriate to its condition will survive and pass on its useful qualities in expanding numbers to the accompanying eras, while those life forms less suited to the earth will be disposed of. . “For example, some cheetahs can run faster than other cheetahs and will therefore be more likely to catch their prey. Organisms that blend into their background and remain hidden from their predators will have a better chance of surviving than those members of their species that cannot” (Arnold, 2009). “Peppered moths - the deer mice are like the classic example of natural selection the peppered moths of northern England” (Arnold, 2009).

Predators, food availability, habitat’s carrying capacity are all examples of limiting factors that play in the population growth, which leads to the process of natural selection. Those who are able to withstand these circumstances are the ones who will be responsible for the next generation, since their genes will be passed on to their offspring. This is how natural selection shapes the genetic pool of a population. Natural selection doesn’t happen in through a short time frame, but rather a process through long periods of time, sorted by the successfulness of a heritable biological trait passed down to its offspring. To help better understand the concept of natural selection, take a population of clams on the beach for an example.

Therefore a particular environment can only sustain a certain population size, which leads to competition between organisms. The 2nd requirement for natural selection to occur is genetic variation, which causes organisms in a population to look/act differently than other organisms of the same species. Genetic variation can be caused by crossing over during meiosis or random mutations. The third prerequisite for natural selection to occur is the struggle to survive. Organisms are constantly faced with challenges in their environment, such as avoiding predators, finding foods, and environmental changes.

Natural selection is the process where organisms become better fitted to their environment and they survive and produce more. Natural selection contributes to the theory of evolution which is when a population gets heritable characteristics over a period of time which sometimes can cause speciation. Three things that support The evolutionary theory are fossils and how they show change, Darwin’s finches, and how organisms can adapt to become resistant. Fossils are a great way to show how evolution happened over the years, for example the pakicetidae. The pakicetidae lived 50 million years ago and is the extinct family of early whales.

Three different sides will be discussed in this paper. First is the theory of natural selection, often called the survival of the fittest. Natural selection as quoted by the Merrium Webster Dictionary is, “a natural process that results in the survival and reproductive success of individuals or groups best adjusted to their environment and that leads to the perpetuation of genetic qualities best suited to that particular environment.” For example there is a litter of cats. One of these cats is a lot faster than the other cats and is therefore able to get food easier.
