Natural selection: the process by which individuals with certain heritable traits tend to produce more surviving offspring (increasing its fitness) than do individuals without those traits, often leading to a change in genetic makeup of the population (increasing variation)…
The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection is evolutionary adaptation, a prevalence of inherited characteristics that enhance organisms’ survival and reproduction in specific environments.…

As a result of natural selection, a population—a group of individuals of the same species living in the same place at the same time—can change over generations. Natural selection leads to evolutionary adaptation, a population’s increase in the frequency of traits suited to the environment (Simon, Reece, Dickey, 2010).…
* natural selection-The process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the same species.…
Natural selection describes how the evolution of a species is determined by the traits they develop to survive. Because a species develops specific traits the structural formation of…
The purpose of this lab was to have a clear understanding of natural selection by demonstrating the different factors that contribute to the process. By playing the roles of predator and prey in the simulation multiple generations of the spoon, fork and knife could be mimicked to show natural selection in the real world.…
Lab #2 focused on the predator prey concept. Charles Darwin’s concept of survival of the fittest is what was tested in this experiment. Darwin’s concept of survival of the fittest states that the animals that are able to adapt to their environment the best are the ones who will survive and pass on those adaptations to their children. Animals adapt for many different reasons some of them might be to help defend against a predator, to be able to retrieve food more efficiently, or just to help them live in a harsher environment. The animals that are able to adapt to their situation the best are the ones that will be able to live on and reproduce the ones that are unable to will die off. In order to test this theory we used 100 paper chips ten of ten different colors and two different pieces of cloth to simulate an environment. We put the chips on the pieces of fabric and then turned around so we were not facing the fabric so when we turned to face it we could pick the first one we saw and then turn back around. We did this three times for each fabric.…
Natural selection was first noted by Charles Darwin and his theory of evolution originates mainly from his observations of the Galapagos finch (Clegg, 2007) and how the species had evolved over time to best survive dependent on their environments. Darwin’s theory considers that each and every species is subject to change, evolving to better suit their…
Natural selection is when members of a population have an enhanced survival characteristic, which will then allow them to reproduce more offspring that will survive to a reproductive age, which will further pass on this enhanced characteristic. The reason natural selection came into play was because of the Industrial Revolution in England. There was an increase in pollution because of the burning of coal and other aspects the new industries produced. This environmental selective agent, soot, caused the lichen on the trees to die, and also caused the trees to have a…
Natural selection is a mechanism for the evolution of a population to become better adapted to their local environment over many generations. As we explore how natural selection works, pay attention some of its main principles: variation, overpopulation, adaptation, and descent with modifications.…
- The theory of Natural Selection: the process in which individuals that are better adapted to their environment survive and reproduce more successfully than less adapted individuals. Their environment selects the traits.…
Natural Selection is when each generation of a species develops new characteristics and adapts more to the environment to survive. This theory of evolution caused some controversy because it contradicted the beliefs of many religious leaders. It also caused scientists studying the field to reevaluate everything that they had learned! Some people tried to use this theory to justify acts like slavery and genocide. Natural Selection was used to imply that these behaviours were natural.…
By definition, natural selection theory is whereby the organisms that have adapted well to the environment can survive even during the times of scarcity and have offspring. The theory involves both competition and cooperation. According to Darwin, competition and cooperation are related to power such that, in life competition will always be there where people and animals must strive for the scarce resources (Darwin 29). During the competition, the strong ones will win and take the power. Cooperation is a key factor during competition. Only those who tend to cooperate with their members have high chances of winning. Also, the interrelationship between cooperation and competition can give rise to power where those who…
Since the natural resources are usually limited, the reproduction results to competition for survival by utilizing the scarcely available resources. Species of organisms that posses traits that give them advantage over the others, they usually survive and pass the traits to the next generation unless the others organisms lacking the traits which do not survive the competition. Thus the process of natural selection is determined by the organism’s evolutionary fitness which shows the ability of an organism to survive and reproduce and determines the amount of genetic traits to be passed to the next…
