Charles Darwin, born into a free-thinking family, created a theory to which many continue to study today. The theory of natural selection is a notion that all life is related and has descended from a common ancestor; from plant life to the animal kingdom. This specific theory states as if all complex creatures evolved and matured over time from simple creatures who adapted with the environment. Said theory suggest beneficial mutations, the dying of weaker fractions of the species; while stronger and more superior fractions live on, but it is a slow gradual process. The basis of the theory is understanding of how natural selection works. Natural selection can change a species in small ways, causing a population to change color or size …show more content…
Natural selection is the gradual, non-random process by which biological traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution. The term "natural selection" was popularized by Charles Darwin who intended it to be compared with artificial selection, what we now call selective breeding.Offspring would inherit that advantage and pass it on to their offspring. The disadvantaged members of the same species would gradually die out, leaving only the advantaged members of the species. Natural selection is the preservation of an advantage that enables a species to compete in the wild. Natural selection is the the same as domestic breeding. Over the centuries, human breeders have produced dramatic changes in domestic animal populations by selecting individuals to breed. Breeders eliminate undesirable traits gradually over time. Similarly, natural selection eliminates inferior species gradually over …show more content…
This type of selection is what most people think of as natural selection, but it also comes in two other forms.Stabilizing selection occurs if a species is already well adjusted to its environment. Some cases of said selection, the individuals with basic characteristics leave the most offspring, and individuals that more different from the average leave a fewer amount of offsprings. Unlike directional selection, stabilizing selection eliminates the greater or more extreme characteristics, reducing the amount of disparity in a population. Stabilizing selection may actually be the most common type of natural selection in the animal kingdom.Sexual selection occurs primarily among animals. Adults of many species prefer mates who display certain behaviors or have certain external features including bright colors or

Essay about Darwinism: Charles Darwin and Natural Selection

Darwinism Darwinism refers to the theory of evolution, but in particular, evolution by Natural Selection. The phrase was coined by Charles Darwin, who brought the theory of natural selection to light in 1859. His book, On the Origin of Species by Means of Natural Selection, presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. We know natural selection as adapting to your environment, and according to Darwin, these variations accumulate…

The Struggle Between Natural Selection And Social Darwinism

Charles Darwin observed that all living organisms produce more offspring than can survive in a given environment, thus there is a struggle to survive. Offspring with features that are beneficial to survival for the environment tend to survive, while the offspring with non-beneficial features tend to die. For example, if there is a shortage of food in the environment of giraffes, only the giraffes with long necks will survive and reproduce. In other words, there is a survival of the fittest in which…
