Children often play a game called telephone, where one child whispers a statement into another child's ear, and the statement is passed on to other children; at the end of the game the last child will repeat the statement that was told to him or her. The majority of the time, the statement said would be completely different than the original one. This is an example of evolution through natural selection; where somewhere along the life span of the statement, it was modified, and the modified statement was passed on to form a new statement.
Charles Darwin stated that, "individuals are the unit of selection; the struggle for existence is a matter among individuals." In this statement Darwin is referring to natural selection. Natural selection is defined as the differential contribution of offspring resulting from variations in heritable traits. As a result of natural selection, certain individuals in a given population produce certain traits that others do not. Natural selection is the only agent that adapts organisms to their environment; if a species cannot adapt to their environment, eventually they will be extinct.
In my visit to the American Museum of Natural History (AMNH), I observed many interesting things concerning the issue on evolution and natural selection. An example of evolutionism I saw in the AMNH was the Hall of Human Biology and Evolution. This hall concentrated on human evolution and how certain traits arose through successful generation—such as the change in the skeletal system as a result of walking upright. Fossils of Australopithecus afarensis, which is believed to be the earliest human relative, are dated back nearly 4 million years.
The Hall of the Vertebrate Origins is another exhibit that shows evidence of evolutionism. The purpose of this hall is to show that all vertebrates had a common ancestor. That common ancestor had a brain case and a backbone. As time progressed, the vertebrates developed limbs that were supported by the backbone, and had watertight eggs.
The Hall of Saurischian Dinosaurs and the Hall of Ornithischian Dinosaurs are more examples of evolution within vertebrates. However, these two halls do not have much in common with our line of ancestry except for the fact that a backbone and brain case are present; any other things in common with our lineage are but minor details. That is why the AMNH has another hall called Mammals and Extinct Relatives.

The Process of Human Evolution Through Natural Selection Essay examples

- The process of human evolution through natural selection is an idea and a reality that is commonly misunderstood by a part of society. The process of natural selection is a continuous ongoing process that affects all living beings no matter what genus, species or even life form, all forms of life that are capable of reproduction are affected. In order for natural selection to take place there has to be a reproduction process that takes place within that species and pass on its genetic material to future generations....   [tags: reproduction, survive, species]

Evolution Of Evolution And Natural Selection Essay

- Evolution can be defined as the process through which the characteristics of a species undergo changes over a number of generations through the process of natural selection. There are different mechanisms that try to explain the evolution process and these are mutation, migration, genetic drift and natural selection. However for natural selection and genetic drift to take place there must exist a certain type of genetic variation. To begin with natural selection can be defined as the process through which organisms that are better adapted to a certain environment survive and produce fertile off springs....   [tags: Evolution, Biology, Natural selection, Gene]

Evolution And Natural Selection Are Related Essay

- Darwinian evolution is the theory of biological evolution stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual’s ability to compete, survive and reproduce. This theory was settled by Charles Darwin, a naturalist and geologist best known for this evolutionary theory. Darwinian evolution has been around since the 19th century (Darwin C. 1859 Descendant of Man), and has continued to now 2015. Some changes that are provided from Darwin until now includes the discovery of how genes have different biological or behavioral traits, and how genes are passed down to the offspring....   [tags: Evolution, Natural selection, Creationism]

Essay on Natural Selection That Causes Evolution

- Genetic drift decreases genetic variation in a population. It is very important mechanism in addition to natural selection that causes evolution. The process of evolution has been explained through various evolutionary methods in particular molecular phylogenies. Scientists have become very interested in learning about other mechanism beside natural selection that can explain evolution. Natural selection is very important to mechanism that helps explain factors such as morphology, behavior that are related to phenotype which can affect reproduction and survival of an animal....   [tags: Gene, DNA, Evolution, Natural selection]

Natural Selection And Genetic Selection Essay

- “Animals are adapted to their conditions in subtle and marvelous ways (Boyd, R., & Silk, J. 1997:2).” It is commonly recognized that Darwin identified adaptations through Natural Selection: traits that are advantageous to survival will be retained in the population through reproduction. Natural Selection further indicates that traits will survive when they are most beneficial to an individual’s fitness. While Natural Selection and Mutation effectively explains adaptive fitness qualities and variance among populations, it fails to explain species beautiful ornamental traits that are not necessarily beneficial to fitness....   [tags: Natural selection, Charles Darwin, Male, Sex]

Charles Darwin 's Theory Of Natural Selection Essay

- There must be very few people from biology or evolutionary background who are not aware of the work of Charles Darwin. Charles Darwin proposed that evolution occurs through the process of natural selection. Natural selection is the process by which species adapt to their environment in order to survive. Species evolve from one to the next through random genetic mutation, if the said mutation is beneficial then it is preserved and is passed down to the next generation to help with the survival of that species....   [tags: Evolution, Natural selection, Gene]

Essay on Charles Darwin's Theory of Evolution by Natural Selection

- When the name Charles Darwin is uttered, an immediate association brings about the concept of Evolution. Although he was not the first to "discover" this phenomenon, he was the first to explain it. In his book, The Origin of Species, Darwin discusses evolution- through variation, why it occurs, the struggle for existence, natural selection, the geological record, and several other topics. This book brought him great recognition as well as many violent attacks. It was written in a time in history when the people were very strong believers in the Church and God....   [tags: Natural Selection, Evolution Essays]

Essay on Charles Darwin's Theory of Evolution by Natural Selection

- More than a century after his death, and four generations after the publication of his chief work, "The Origin of Species", Charles Darwin may still be considered the most controversial scientist in the world. His name is synonymous with the debate that continues to swirl around the theory of evolution, a theory that deeply shook the Western view of humanity and its place in the world. We tend to speak simply of the theory of evolution, leaving off the explanatory phrase, "through natural selection." At most, perhaps, the general public has heard of "survival of the fittest" a poor phrase as far as I'm concerned, since fitness in everyday usage is associated wit...   [tags: Natural Selection, Evolution Essays]

Essay about Evolution : Natural Selection And Types Of Evidence For Evolution

- All living species will never stop evolving over time due to one important key concept incorporated in the theory of evolution: natural selection (lecture). Impressive, isn’t it. To think that this mechanism has always been present to help the survival of the breathing kind (lecture). Therefore, the objective of this essay consists of demonstrating the notions about evolution and its four mechanisms, the process of natural selection, the theory of natural selection and types of evidence for evolution....   [tags: Charles Darwin, Evolution, Natural selection]

Charles Darwin's Theory of Evolution by Natural Selection Essay

- 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....   [tags: Natural Selection, Evolution Essays]

The hall, Mammals and Extinct Relatives, is devoted to showing how all mammals evolved from the earliest forms of vertebrates. A big evolutionary change that separates mammals from other forms of animals is the development of the placenta and the formation of the middle ear.
The hall that I believe to be the most interesting of all halls in the AMNH, is the Hall of Biodiversity. In this hall we can see a large spectrum of life from the broad "Kingdom" to the specific "Species" is found in this part of the museum. The amount of information that one can obtain from just this hall alone is overwhelming. From the simple far left (true bacteria) to the complex far right of the hall shows us a great difference in species as well as many similarities. But more importantly, the hall shows that many of the more complex living species today have evolved from another living or extinct species in the past. Furthermore, those living/extinct species in the past originated from another more ancient species, and so on.
Natural selection is a nonrandom event and is a process that happens over large periods of time. The offspring that carry a certain trait that is favored due to a certain environment will be carried on more successfully by their offspring. Due to this process change, even if it is minute, will occur over a small number of generations. If such selection continues to occur more complex forms of a simpler body plan will arise.
