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

The formal “Theory of Evolution” thought to have come about by Charles Darwin, is built on the premise that all life is related and has descended from a common ancestor; meaning the birds and the bananas, the fishes and the flowers are all related (“Darwin’s Theory of Evolution”). In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival. This process is formally known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different

First, Charles Darwin’s theory of evolution by natural selection answered certain questions on how certain living things came to be. One thing that Darwin’s theory explained is why organisms have features such as wings, eyes, and kidneys (“Evolution”). This was a theory that shocked the world, as many people wondered how such things were created, but most believing that a God had created living things, and even believing in a different scientific theory, the big bang theory. Also, Darwin’s theory of natural selection explained the multiplicity of plants and animals (“Evolution”). Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring, proving another one of Darwin’s theories, survival of the fittest. Survival of the fittest is the fact that the strongest organisms, mentally and physically, would survive longer by producing more offspring carrying the same genes as the parent organisms (“Evolution”). Survival of the fittest explains why in modern times, people and other organisms are smarter and stronger. Organisms have a better chance of survival when they have certain qualities that prove better than other of the same species. In this aspect, the theory of evolution by natural selection, proposed by Charles Darwin, has benefitted our modern society.

Years ago Charles Darwin created the theory of natural selection. He attempted to explain how evolution worked, and his theory is now regarded as correct. Natural selection states that animals with traits that are better suited to their environment will survive and reproduce more. This would explain how evolution works. Groups of animals with the most beneficial traits survive and are able to reproduce. While the other group has difficulty surviving and would therefore reproduce less. The variation between that type of animal would come from a random mutation which turned out to be useful. An animal may get a mutation which is either beneficial or disadvantageous to the organism (1). As time progresses there are a larger amount of animals with the beneficial trait, while there is a lot less animals with the older trait. Natural selection correlates to the phrase “survival of the fittest” meaning that animals with beneficial traits will survive, while those without will die (2). Theoretically, this could lead to an entire change of the population; leaving only the group that can survive easily and produce more offspring.

Evolution is “the process of which different kinds of living organisms are thought to have developed and diversified from earlier forms at the beginning of time.” At the time most naturalists believed that in the beginning the species were there and they have not changed over time or that the species were created over the course of natural history, they believed that they stayed the same throughout time. Darwin noticed great similarities in different types of animals that linked each other together. This led Darwin to believe that these animals evolve over time and will eventually turn into the species with similar actions and characteristics as their early ancestors. Darwin then began to believe that all species survive through a process called “natural selection” which is when the species that adapt well to the environment live, but if they don’t adapt, they will die. Mentioned in Darwin’s book the “Origin of Species” darwin mentions this quote “Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning

While his theories present an immense amount of knowledge they relied too much on the unseen. Darwin’s explanation of how variation leads to the eventual creation of species is not based on clear evidence, because the distinction between varieties and species had not yet been clearly defined. He also tried to apply the concept to every single organism, meaning that if one organism did not comply with his theory the entire theory would be

Darwin believed all plants and animals had changed from past families by natural selection. An example of natural selection would be the different coloration between beetles (Understanding Evolution, 2008). There are two different colored beetles, one is brown and the other is green. Since the environment cannot have an overpopulation, the green beetles will get consumed by birds and not be able to survive and reproduce as much as the brown beetles. The brown beetles have offspring because the trait has a genetic basis. When they produce more offspring, they become more common in the environment and if this process continues, the population of beetles will be mostly brown. Certain characteristics are innate within a species which help them reproduce and survive more than other species with no such inborn characteristics. These species will become more favorable and most common in the population. Darwin’s theory of natural selection favors organisms that are prone to adapting well to the environment, it makes it easy to pass on their genes stabilizing the population and making it stronger. Species begin to die out according to, what Darwin calls, survival of the fittest.

The theory of evolution by natural selection is developed by English naturalist Charles Darwin. Evolution is defined as, all living species are descendants of ancestral species and are different from modern-day organisms due to the process where there are physical and/or behavioural changes made over time———Natural selection occurs when these changes allow the organism to evolve and better adapt to its environment. This effecting the occurring populations of the species to adapt and change to different behaviour and physical traits. Darwin often describes it as “survival of the fittest”, “fitness’ referring to an organisms ability to survive and reproduce.——— Around 50-60 million years ago, there was thought to be around 350 different species

We live in a world full of mutations. These mutations are sources of variation, and are essential to our survival. As generations of organisms progress, we develop mutations that help us to adapt to the world around us. This is called evolution. Evolution by natural selection is a theory created by Charles Darwin in which he states that organisms evolve over time and develop certain characteristics, and the beneficial characteristics are passed onto the organism’s offspring as to increase the organism’s ability to survive, reproduce, and compete for resources. Natural selection keeps the mutations that lead to an increase in Darwinian fitness, which is the ability to survive

The theory of evolution by natural selection (Darwinism), first formulated in Darwin 's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioural traits. Changes that allow an organism to better adapt to its environment will help it survive and that have more offspring. The first three ideas were already under discussion among earlier and contemporaneous naturalists working on the “species problem” as Darwin began his research. Darwin’s first contributions were the mechanism of natural selection and numerous amounts of evidence for evolutionary change from many sources. He also provided thoughtful explanations of the consequences of evolution for our understanding of the history of life and modern biological diversity.

In 1859, a biologist named Charles Darwin postulated a scientific theory, which stated that all living organisms evolved through a process of natural selection. According to Stephen Hawking, Charles Darwin claimed that the offspring of a particular species gradually evolved themselves genetically to resist the changes in the environment (573). The theory contended that the organisms could adapt to the changes in the environment through the survival of the fittest. Though this theory is regarded as a breakthrough in the field of biological evolution, it is interesting to explore how this seemingly scientific theory has been suitably modified, and intellectually applied to both negative and positive aspects of life.

It can happen many ways like a population to change color or size over the course of several generations. This is called "microevolution." But over time it can become bigger it can create new species, known as "macroevolution." Darwin did know anting about anything about genetics or how much it effects it how things works. That came later, with the discovery of how genes encode different biological or behavioral traits, and how genes are passed down from parents to offspring. The incorporation of genetics and Darwin's theory is known as "modern evolutionary synthesis." The way physical and behavioral changes that make natural selection possible goes to DNA and genes. When it changes its known as mutations. "Mutations are basically the raw material on which evolution acts," Pobiner said. Mutations can be caused by random errors in DNA replication or repair, or by chemical or radiation damage. Most times, mutations are either harmful or neutral, but in rare instances, a mutation might prove beneficial to the organism. If so, it will become more prevalent in the next generation and spread throughout the population. So think of like spider man he was bit by a radioactive spider and instead of getting cancer he changed for the better. (I am not condoning for you to get by a radioactive spider just avoid radioactivity

Darwin's theory of evolution is that organisms change over time as a result to adapt the changed environment. Darwin’s theory of evolution was by natural selection it is when an allele changes over a period of time. Natural selection occurs when populations evolution can not occur in a single individual. There are certain types of natural selection like stabilising, directional and disruptive.

Modern day society, even with all of its technological and cultural advancements, still struggles with the question of “How do we love?” To put it in simpler terms, what factors exactly play a role in who we as human beings choose in partners over another? What attracts us to one person and not another? It is hard to imagine a concrete formula that works for each and every individual on the planet, since there are infinitely too many factors that play into the development of attraction between individuals. The advent of society has served only to introduce even more possible factors of attraction, which further complicate the issue. Whereas animals may choose to mate with each other due to a display of superior genetics, humans have to contend

Population of species increases from one generation to another, at a constant rate. If those generations then reproduce in larger amounts, while the death rate does not change and the room on earth remains unchanged, there will be no more room left. Nature creates a limitation on the amount of organisms that can live on earth and organisms have to strive to survive by competing. Offspring survival is significant to Darwin’s theory; this is due to the continuance of beneficial traits to be passed down to further generations, which are depended on. The members within the same species that have the advantageous traits will more likely survive, while competing with members of other species as well. Advantageous variations are what results to survival, along with reproduction. Change is created within species, preparing subspecies to adjust to its surroundings. Struggle for existence can occur in different ways and Darwin discuses how populations of species that are larger have a higher survival rate because they have a less chance of being killed by a predator. Larger populations also easily maintain high numbers by

Charles Darwin was a British naturalist who proposed the theory of evolution by natural selection in his controversial book On the Origin of Species. Darwinian evolution states that all species on earth gradually evolved from one common ancestor through natural selection. His theory can be broken down into six components: evolution, gradualism, common ancestry, speciation, natural selection, and nonselective mechanisms for evolutionary change. Evolution simply means that a “species undergoes genetic change over time.” Due to DNA mutations, these genetic changes in species form completely new and diverse species over several generations. This explains the wide variety of life found on Earth today; life on Earth today descended from life in the past, yet greatly differed from it. The second component of Darwinian evolution is gradualism. Evolution takes time. It takes multitudinous generations to produce significant evolutionary change. This does not mean that all species evolve at the same rate. The theory of evolution does not predict the rate at which species evolve. The environmental factors affecting different species determine how fast or slow evolution occurs. Typically, evolution slows down once a species adapts to the environment. Common ancestry indicates that all species share a common ancestor who passed its traits to its descendants. But, how is the diversity of life explained then? This leads to speciation which is how new species evolve from old species because
