Charles Darwin's Principles Of Natural Selection

“It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.” Charles Darwin's theory of evolution by natural selection remains one of the best known theories in science today. However, The Origin of Species had a significant impact on society when it was published in the late 19th century. The idea of evolution and natural selection uprooted many popular ideas at the time and led to the creation of new movements. Charles Darwin's theory of natural selection impacted 19th century society in a scientific perspective, a sociological perspective through the rise of social Darwinism, and a theological perspective in the debate between evolution and creationism.

Natural Selection, a key mechanism of evolution is the progressive process by which biological traits either become more or less common in a community or population as a result of inherited traits on different reproductive success of organisms with their environment. Charles Darwin in fact put together an articulate theory of evolution and supported it with a good amount of body evidence in 1859 when he published his book. Natural selection is too however a basic mechanism of evolution like mutation, migration and genetic drift. In order for natural selection to work, Darwin came up with 5 different theories that brought about evolution. The five theories are: evolution, common descent, species multiply, gradualism, and natural selection itself. Evolution is when species come and go through time, while they exist they change. Common descent is organisms are descended from one, or several common ancestors and have diversified from this original stock. Species multiply is the diversification of life involving populations of one species diverging until they become two separate species; this has probably occurred billions of times on earth. Gradualism is evolutionary change occurring through incremental small changes within populations; new species are not created suddenly. Animals and plants of all sorts undergo changes through natural selection. The peacock is a unique animal that stood out to me that undergoes natural selection.

In this work, Charles Darwin frequently observes and references the variation in traits amongst individuals in a population. He observed that nature selects from existing varieties the traits most suited for a particular environment. He also proposes that species descend from common ancestors, undergoing various modifications in the course of time. This concept is described by Darwin as “descent with modification” or the new variations present in new generations resulting from natural selection. One of Darwin’s more convincing points is made by way of metaphor. He wrote, “The face of Nature may be compared to a yielding surface, with ten thousand sharp wedges packed close together and driven inwards with incessant blows, sometimes one wedge

Charles Darwin has probably made the most significant impact on our modern ideas of evolution. Although he wasn’t the first person to think of evolution, he was the first to try and test it. He then published a book based on his research called The Origin of Species. In his book, he covered five major theories: evolution—species can change over time, common descent—all living things share a common ancestor, speciation—the population of one species separating into two separate species, gradualism—biological change in a population at a slow and steady rate, and natural selection. Natural selection being the dominant force in a much bigger idea where all five occur simultaneously, evolution.

Darwin argued that, the population of any specie , at a specific time in evolution, includes individuals of varying characteristics and ensure that, The next generation of that population will contain characteristics of those individuals that most successfully survive and reproduce under the existing environmental conditions. However, this characteristics of various types within the species will change or evolve over the time. This theory is based in 3 principles:

Through his observation of finches, Darwin enumerated the three conditions or traits necessary in order for natural selection to take place. However, these three conditions convey only what was observable at the time, rather than the underlying genetic processes taking place. His first condition was that, “There is variation among individuals.” What Darwin observed was morphological or phenotypical differences, and these in turn produced an individual either better or worse suited to survival and reproduction. Second, “The variation is inherited by offspring,” means that these differences in traits must be able to be passed down to future

Natural selection is one of the most significant methods in which evolution can occur in a population that was proposed by Charles Darwin, among other scientists, in the 1800s. The term summarizes the concept that heritable traits that are able to survive, due to fitness for their environment, and successfully reproduce will likely become more common among a population. On the other hand, natural selection also includes the idea that heritable traits that either cannot survive, or have unsuccessful reproduction will become less common in a population. Other aspects of natural selection as a whole include evidence from various scientific fields, the key points of the process, its causes, and its effects.

Over time, different species learn to adapt to their living environment in order to survive. If a genetic change of a characteristic is passed down through generations, a formation of a new species occurs (G, Linstead et. al., 2012). A variation to the characteristic of an individual can increase its survival and this provides more opportunities to reproduce. When the individual reproduces, the offspring benefit in result of the heritable genes and eventually through generations, the variants will be spread throughout the entire population (Montgomery, 2009). Charles Darwin’s theory of natural selection can be supported through both fossils and homologous structures.

Charles Darwin is the founder of Social Darwinism, as he created the theory of evolution by natural selection. Social Darwinism is the theory that people are subject to laws of natural selection.

Darwin’s hypothesis of natural selection is contradictory when compared to the Hardy-Weinberg equilibrium condition. Hardy Weinberg states that there are no mutations resulting in unchanging allele frequencies and new alleles aren’t introduced. However, Darwin points out that traits leading to better survival and reproduction must be heritable. The fittest will mate and produce more desirable traits, which will then be passed down to future generations resulting in new alleles. Hardy Weinberg’s equilibrium also specifies that there is no selection among genotypes, contradicting Darwin’s idea that the “better” variation must have a higher survival rate. If there is no selection, then everyone has an equal chance of surviving and an equal

Charles Darwin came up with the theory of “Natural Selection,” which explained how animals produce offspring that will replace them. The theory of “Natural Selection” also fits the phrase “survival of the fit,” which became (or evolved - how fitting) “survival of the fittest.” Basically, animals eventually adapt to their environments through evolution. The evolved organisms, or the “fittest,” will end up surviving better and longer than those that are not as adapted.

Natural selection is how animals evolve over time and develop traits that help them survive in their environment. Darwin's theory was directly related to psychologist William Jame's ideas of functionalism which was that different behavioral traits get passed down through their heredity or through learning from a prior generation. The study of heredity was still in early phases he believed that they could be passed down from human to human genetically. (Ciccarelli & White, 2015, p. 8) Both James's and Darwin's theories would mean that as people and animals adapt the genes that create a specific weaker traits begin to make the holders of those genes die out over time, until the gene is completely removed. This is why people use the term selected

Charles Darwin broached the theory of natural selection in his book the Origin of Species, which has been considered the basis of evolutionary biology to this day. Natural selection is when populations of a species evolve over the course of many generations. Darwin believed that species were not created separately, but instead, species were derived from one another. In other words, the evolution of species creates many variations among creatures, and this is because all of those species came from a common ancestor, and characteristics changed to increase the species chance of survival.

In this writing prompt I will tell you all about Theory of Evolution. First, let’s get to know the meaning of evolution. Evolution is a species over time; process of biological change by which descendents come to differ from their ancestors. They say evolution is a scientific theory because in science, a theory is the most well thought-out simplification for how a natural phenomenon service. Inborn traits that assist organisms survive and duplicate grow further usual in a population over time. They explained Darwin’s theory through natural selection. Darwin's Theory of Evolution is the generally held belief that all living is associated, and has dropped from a common ancestor

Charles Darwin was born in Shrewsbury, England, on February 12, 1809. He died on April 19, 1882 in Kent, England (Biography.com Editors). Charles Darwin brought many revolutionary visions to the world of science, including evolution. Charles Darwin was an English naturalist and geologist. He is best known for his theory of evolution, and natural selection. Darwin learned most of his information on the Voyage of the Beagle, and from this trip he wrote a book, Of the Origin of Species. From this book, came the saying “Survival of the Fittest.” Charles Darwin accomplished many things with his life. He still has many fans and followers because of his discoveries.
