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).…
Today, natural selection is defined as the process whereby organisms better adapted to their environment tend to survive and produce more offspring. Darwin and Wallace are best known for their efforts in discovering how organism evolve and reproduce. In the late 1800s Wallace developed an understanding of how organisms are the way that they are. Following in Darwin’s footsteps, Wallace set out at sea to explore different islands. He concluded that Islands that are near each other tend to have similar but distinct animals living on them. Also, that certain organisms have specific geographic ranges but that organisms that are more similar, tend to live closer together. Throughout his travels, he found that on the Malay Archipelago Birdwing butterflies…

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…
Natural selection is a process where the differential survival of reproduction of individuals in a population brought about the evolutionary change. In this process population adapts to their changing environment. there are other forces that can cause evolutionary changes in the genetic makeup of a population. Change is one of them. Most people believe traits and populations can evolve. Pesticide resistance in insects and antibiotic resistance in bacteria are evolutionary changes in biology populations that have been observed many times. Microevolution are changes that occurred within the biological population. The changes that result in the origin of a new species…
Natural selection is the process by which organisms with variations most suited to their local environment survive and leave more offspring. Natural selection “drives” evolution.…
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.…
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…
Charles Darwin was the man who thought of this idea of natural selection. I believe that natural selection is a process of evolution that helps many species survive and thrive in their environments. Natural selection helps species adapt to new or changing environments to help them survive better. An example of natural selection in the real world would be the pollution of a lake causing it to become darker then slowly over time as the fish reproduce there would be no light fish, all fish would be dark. Natural selection is basically survival of the fittest. Natural selection has allowed a variation of species to thrive in different…
I chose to read and evaluate an article called 'Human Evolution: New Playgrounds for Natural Selection'. This article was published on May 20th 2013, by Emmanuel Milot and Fanie Pelletier. This article was published in the 'current biology' journal volume 23, issue 10. I chose this article because it deals with natural selection, which was talked a lot about in Chapter one in our learning and behavior book. Over time a lot of change took place, and a lot of it was due to natural selection and how our bodies and traits changed over time to deal with the new challenges faced everyday. According to the New World Encyclopedia "Natural selection is the process by which biological organisms with favorable traits survive and reproduce more successfully…
The theory that members of a species each have slight variations from each other, and that these variations have the ability to enable some members of a species a survival advantage in certain environments. As a result of having a variation that increases their likelihood to survive, they are allowed to propagate, and their offspring have an increased likelihood of survival with the passage of the variation. Other members of the species who lack the variation die, and over time the only surviving members of the species are the ones who possessed the variation that gave them the survival advantage.…
