Evidence Used To Support Evolution Essay

449 Words2 Pages

It has been discovered that evolution is not the survival of the best organisms, only the ones who are best adapted to their environment (Daempfle, 2016). The weaker organisms are separated from the stronger ones, however, the stronger ones do not always survive. There are more than four pieces of evidence used to support evolution, nevertheless, there are four very important pieces of evidence used to support the theory of evolution. First, evolution is change in the heritable characteristics of biological populations over successive generations,” (Wikipedia, n.d.). Evolution in organisms occur through changes in heritable traits. For example, eye color is an inheritable trait. Inheritable traits are controlled by genes, and genes are grouped …show more content…

During natural selection, nature is selecting attribute for the organism. An organism’s phenotype results from its genotype and it results from the influence from the environment that it has lived in, and a substantial part of the variation in a population is caused by genotype variation (Wikipedia, n.d.). The frequency of one allele will become more prevalent or less prevalent to other forms of the gene (Daempfle, 2016). Variation ends when a new allele reaches fixation, and when variation disappears from the population, it replaces the ancestral allele completely. Mutations are changes in DNA and a cell’s genome. Mutations, then often prevent genes from functioning (Wikipedia, n.d.). The majority of mutations have damaging effects. However, the ones that remain neutral have few benefits. Gene flow is the exchange of genes. This happens when populations exchange genes with different species (Wikipedia, n.d.). This happens when organisms move from one place to another. One example is when pollen moves to grass and adaptation is the process that ensures that organisms are better suited for their environments (Wikipedia, n.d.). Adaptations are created by natural selection. A good example is a horse grinding its teeth when it eats grass (Wikipedia,

The elementary idea is that whenever there will be change, the organisms which are best suited to the environment or circumstances will thrive, these organisms will be developed successfully in the new circumstances. Those organisms that are not suited ideally or less suited, will not be able participate in competition; they will not be developed in the new environment. Darwin observed this in some

How Did Darwin Contribute To The Evolution Of Species

619 Words | 3 Pages

Darwin work On the Origins of Species had a great significance on the process of adaptation, and all more imperatively, a hypothesis that could clarify how new adaptation emerged. Darwin speculated that the minor varieties we see inside a solitary animal varieties, for example, varieties in size, shape, and shade of life forms. The features of these animals are identified with the more particular varieties seen on different species. Darwin work wasn’t the only theory supporting adaptation, before him his father and evolutionary theorist Jean Baptiste Lamarck had similar ideas.

Comparing The Environment And Biologica Biological Adaptation

721 Words | 3 Pages

With constant, varying levels of environmental stress, human beings develop biologically in order to respond to these stresses, leading to the creation of a trait that can be inherited from generation to generation. These genes that are developed are continuously passed on in order to offer an advantage in response to these stresses, however, the development of these genetic changes usually take many generations to develop to its full capability (Anthro Palomar). Natural selection, the process in which an organism that is better fit to its environment survives and continues to thrive while the weaker organism dies out is also significant in the explanation of biological adaptation. The better fit organism has adapted biologically in order to survive in its environment and has developed genetic traits in order to do so, while the weaker one has not or cannot develop in this

The Pros And Cons Of Natural Selection

918 Words | 4 Pages

Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer ["Natural Selection and Speciation - Biology."]. One example of evolution through the process of natural selection is that of the Viceroy butterfly. The Viceroy butterflies were facing extinction a little more than 100 years ago due to their inability to protect themselves or hide from their predators; mainly birds.

Charles Darwin Thesis Statement

Natural Selection is the long gradual process in which Biological traits either become more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. In Darwin’s work The Origin of Species he also mentioned evidence for the Theory of Evolution from his voyage around the world on The H.M.S. Beagle. The Origin of Species is probably the most influential work on evolutionary biology. The Origin of Species will help prove my thesis because it introduces the ideas that we base on evolutionary biology today.

Human Selection Vs Natural Selection

325 Words | 2 Pages

Natural selection is a process where an organism within a species has specific traits that allow them to survive and reproduce. Natural selection occurs when at least one organism in a species contains a trait that improves their ability to survive and reproduce in a given environment. These traits are created by a process called mutation, which is an alteration in one of the genes in a genome that creates an unusual change in an organism, whether it be internal or external. These mutations can either be good or bad, depending on whether it aids the fitness of an organism. Fitness is essentially the ability to survive to reproductive age, find a mate, and produce an offspring.

Is Evolution Beneficial Or Harmful To A Species

147 Words | 1 Pages

Evolution plays a large roll in the orginization of living organisms. Evolution, adaptation, and random mutation could assist in the organization and survival of living organisms. Evolution is the change of a species over a long period of time. Evolution helps a species survive in an entirely new environment, or under completely new circumstances. Evolution and adaptation help a species better survive and thrive in a certian environment, or with other species threatening their survival.

Natural Selection Research Paper

324 Words | 2 Pages

Charles Darwin’s theory of Natural Selection is defined as “The most critical mechanism of evolutionary change; refers to genetic change or changes in the frequencies of certain traits in population due to differential reproductive success between individuals.” Natural Selection involves organisms and individuals adapting to their environment. It is the key to evolution to which it occurs over several generations. Its process encourages beneficial genes to be passed to further generation and discourage the passage of harmful or less valuable genes. It is a gradual process where some biological traits become more common, while some become less common.

Genotypes In My Family

707 Words | 3 Pages

Heredity is basically the passing on of genetic traits from parents to offspring. Both phenotypes and genotypes are passed down from one’s parents. A genotype is the genetic code of one’s cells. These genetic codes consist of paired alleles and often fall into three categories: homozygous dominant (BB), Homozygous recessive (bb), and Heterozygous (Bb). Phenotypes are the physical expression of genotypes, for example, whether someone has freckles vs. if someone does not have freckles.
