Evolution By Natural Selection In Charles Darwin's Theory Of Evolution

Darwin collected and described thousands of animals and plants. In South America he observed the adaptations of organisms to a variety of habitat from jungle to grassland to mountain habitats. In the temperate regions the species resembled more closely the species of the tropical regions of South America rather than the corresponding species of the temperate regions of Europe. For example, in the grasslands of Argentina there are no rabbits, however, there are rodents that resemble rabbits; these rodents are unrelated to European rabbits but are similar to other rodents in South America. Moreover, the fossils in South America are dissimilar to European fossils but have similarities with extant (i.e. currently living) plants and animals

Darwin theory, he first started talking about an organism, his theory was that in a population shows a difference in traits. The following theory was survival of the fittest, it is when one appears to look like their parents and they are comfortable in their environment, and has the possible to live longer and might reproduce being relaxed in their environment. Beneficial Traits is to increase in frequency over time in a population since individuals with traits are more likely to produce and will pass on the gene to the next generation. It is not important to be a perfect specimen, but important to produce more babies. In addition, Darwin theory was based on the

Darwin’s process of natural selection has different components. Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. These variations may involve body size, hair color, facial markings, voice properties, or number of offspring. On the other hand, some traits show little to no variation among individuals—for example, number of eyes in vertebrates.

Charles Darwin's theory of evolution centres on the idea that species compete to survive, and favorable characteristics are passed on from one generation to the next. Darwin said that evolution took place by a process of natural selection or survival of the fittest. This meant that the animals and plants best suited to their surroundings survived and were able to pass on their genes to their offspring. The ones that weren't best suited died off and didn't get the chance to reproduce.

Darwin’s theory of natural selection has provided us with the explanations of the processes involved in the changes of species over long periods of time. His theory was based on five major assumptions: VARIATION: When Individuals within a species differ from one another in physical characteristics and in their behaviour. HERITABILITY: Some of the variations amongst the members of species is inherited, meaning that the offspring tend to resemble their parents more than the other members of the species. COMPETITION: Members of most species produce far more offspring than can survive.

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

According to history, Charles Darwin is the first scientist to frame the theory of evolution by natural selection. It was publish in his book title "On the Origin of Species 1859”. Darwin express the theory of evolution by natural selection as a process by which species change over a period of time. This change take place because of the changes in genetic and behavioral traits. The ability of the organisms to change over time or adjust to fit environmental factors is due to the ancestral trait. The evolutional theory was supported by great body of evidence from various scientific disciplines.

Charles Darwin was the creator of Darwinism which is, “the theory of evolution by natural selection” (Junker 1). In school we are often taught that natural selection is survival of the fittest or the strongest wins. What seems to be a simple topic is actually one of the leading theories on the side of evolution in the highly controversial debate on Darwinism vs. Creationism. Darwinism states that certain genes in a population change through individuals. These “strong” genes are then produced more and are better able to survive making them the fittest. According to natural selection this process of evolving “usually takes place over many years, but in fast-breeding organisms it can occur rapidly, for example the spread of antibiotic resistance in some bacteria” ("Natural Selection” 1).

In the beginning people had trouble understanding how the world was created, and how humans evolved. As the world grew and species of all kind grew with it, humans created different theoretical explanations on how the; World, People, Animals, Plants, etc, was created. Charles Darwin a famous scientist created the theory of Evolution, Darwin is known for this.

My perspective on evolution is that I am a christian. So it is difficult for me to try to grasp the concept or accept Darwin’s theory. I was hesitant to take this class because of my religious belief. Although, despite being uncomfortable I did not want to drop the class because I think learning about evolution is valuable. In all regards I respect science and the scientific methods. Therefore, I do not think that evolution is false, yet I am struggling to find a parallel between the book of Genesis and evolution. Overall, I want to respect people who believe in evolution and I do not want to be someone who tries to disprove any beliefs that any human being has. All in all I just want to be educated to become more human and understand evolution.

The theory of evolution by natural selection exercises two major concepts. The first concept being evolution, which is what happened to all species. Secondly, natural selection is the concept of how the evolution happened. While Darwin was not the first to propose the theory of evolution, he and a man named Alfred Wallace were the ones to offer intelligible descriptions of how this phenomenon occurred.

Charles Darwin was naturalist which means a scientist who studies nature. He did most of his research on the British ship HMS Beagle. His most famous journey was when he went to the Galapagos Islands. While he was there he saw on each island that the Finches had different types of beaks. In all he discovered 13 different kind of species of Finches.He noticed that thin beaks were meant to help eat insects while a bird with a long beak helps that each food in trees. This made him think that animals were adapting to their environment to help them survive . Also he thought all of these finches evolved from a common ancestor. This research supports his theory of evolution by natural selection because these Finches inherited advantageous traits

Darwin’s Theory of Evolution by natural selection was not intended to be compared to humans, but designed to classify the various species of animals on Earth. Many scientist thought Darwin’s theory could be used to classify humans. Not only did scientists begin creating their own theories on how humans could be classified but started classifying humans according to race. Herbert Spencer was one of the first scientist to start classifying humans by brain mass (Jackson and Weidman 80). In addition to Spencer, other scientists believed humans could be classified by various characteristics. Ernest Haeckel believed that every human race could be traced back to different species (Hall). Haeckel’s strong belief system founded the Monist League. “Members

The word science comes from the latin word scientia meaning knowledge, which is the condition or fact of being aware of something. Knowledge could be attained through various ways. It could be familiarity, gained through experience or learned through observation using one’s given senses. It could also be attained through cognitive reasoning, as coming to a conclusion. Consequently, the range of one knowledge varies and is tested through various types of examinations.Nevertheless, having knowledge does not mean that knowledge is true. Two individuals may observe the same thing but may come to two different conclusions., depending on their perspective. Then who is to say which one is right. That is when science comes in, it is a systematic process of examining a deduction or an infere from an observation.
