One of her most intriguing essays is that of Darwinism. Darwinism is one of the most widely admired and taboo-bounded idols of this age and time. To say that Robinson had a difficult task writing against it is an understatement. However, she does so with great reason and imagination. She provides firsthand evidence and realistic arguments that is very unique in this time.…

Essay #1Four contributions Charles Darwin contributed to the field of evolutionary biology were: non-constancy of species, branching evolution, occurrence of gradual change in species, and natural selection. Each of his contribution became the foundation of evolutionary biology and can be seen in the wild very commonly. Non-constancy can be observed though variation in the offspring. For example, different sized beaks in finches display variation in the species and therefore, non-constancy. This can cause change in the gene pool of a species over time. Many evidence of branching evolution can be seen in the anatomy of different species like homologies and vestigial structures. In whales, the hip bones are similar to humans which indicates the common ancestry between the two species. Gradual change is displayed by the fossil records of many species. Older fossil records have some small differences from the newer fossil records which can be used to prove gradual change in species over time. These changes occur due to mutation and are picked out by the natural selection. These mutations accumulate over time and cause the species to look drastically different after many decades. Natural Selection picks out individuals better suited for the environment and allows them to reproduce and pass on their gene while unsuited individuals die without passing on their gene. Natural selection occurs every time a predator feeds on the weakest, slowest, worst camaflouged, or most un-adapted prey. This allows the gene pool of the species to evolve and shed off undesired genes.…

In the essay “Darwin’s Middle Road”, Stephen Jay Gould describes Darwin’s process on his theory of natural selection. Gould describes the process of scientific creativity with inductivism and eurekaism. Darwin’s thought process also incorporates Frye’s three levels of the human mind. Darwin begins his thought process aboard the Beagle. During these five years, Darwin makes observations of the bones of giant South American fossil mammals. He focuses on the turtles and finches of the Galapagos. According to Gould he mentions “The first ̶ inductivism ̶ held that great scientists are primarily great observers and patient accumulators of information. For new and significant theory, the inductivists claimed, can only arise from a firm foundation of facts.” (Gould 1018). Darwin uses his consciousness and awareness; to identify and give qualities to the turtles and finches. Darwin builds his foundation of facts. Darwin transitions his thinking process to social participation. Darwin takes his facts on finches and brings them into human shape. Darwin begins researching and studying the nature of the finches. Darwin uses social participation to contribute to science. Inductivism corresponds to the first and second levels of the human mind. In addition, Darwin uses the third level of the human mind to create his theory. Darwin’s theory is survival of the fittest through natural selection. Darwin experiences…

Charles Darwin’s work in natural selection and the theory of evolution helps us answer the basic question that befuddled all of man, where do we come from? At the turn of the 20th century, there were only considered two major competing theories that would solve that basic human conundrum. Those theories, evolution and creationism; represented conflicting assertions to answer it. Evolution represented science’s opinion of how the universe began, and creationism offered the religious explanation. While Darwin’s theory has stood the test of time and has been proven correct on many fundamental issues such as natural selection, diversification and the general thesis of mutation and change over a long period of time, the theory still contained gaps that were left unreciprocated.…

By David Quammen Evolution by natural selection, the central concept of the life's work of Charles Darwin, is a theory. It's a theory about the origin of adaptation, complexity, and diversity among Earth's living creatures. If you are skeptical by nature, unfamiliar with the terminology of science, and unaware of the overwhelming evidence, you might even be tempted to say that it's "just" a theory. In the same sense, relativity as described by Albert Einstein is "just" a theory. The notion that Earth orbits around the sun rather than vice versa, offered by Copernicus in 1543, is a theory. Continental drift is a theory. The existence, structure, and dynamics of atoms? Atomic theory. Even electricity is a theoretical construct,…

The well known ecologist Charles Darwin exhibited the hypothesis of natural selection. He went on numerous trips to the wildlife, taking after his interest of the nature and the change that happens in the nature. After examining different kinds of living organisms, he clarified Natural Selection as "preservation of favorable variations and the rejecting of injurious variations."(900). Darwin utilized relations and demonstrations to show that distinctive changes happened in the same specie, which assisted them with adapting to their environment.…

For those of you who took biology last year and did not pay attention when we were learning about Charles Darwin and Natural Selection, here is your chance to learn how he made a big impact to his time. Charles Darwin, a Naturalist and an Influencer, revolutionized science from his theory of evolution by Natural Selection. Expanding on that idea, He developed his Natural Selection theory by going on a 5 year survey trip on the HMS Beagle around the world suggested by his mentor and old professor John Stevens Henslow. A lot of you may think that Darwins voyage seems fascinating and spectacular and I bet it was; however, when he arrived back from his trip, he got very sick and suffered chronic illnesses such as heart palpitations…

Evolution is basically the change in the heritable characteristic or traits in living organisms which are passed from one generation to another and gives rise to diversity at every stage of the organism’s biological organisation. The process of evolution was not well understood until 19th century when Charles Darwin proposed the scientific theory of natural selection as a driving tool in evolution. The process involved both the macroevolution in which organisms went through major evolutionary changes over a long period of time and acquired different traits from different parents or ancestries and the microevolution in which a group of organisms went through minimal changes with time but the traits they acquired were typically from the same ancestor.…

Darwin’s theory of evolution is based on the theory of natural selection. Natural selection is the the process whereby organisms better adapted to their environment tend to survive and produce more offspring. This theory is now widely believed by many people throughout the world. Charles Darwin’s theory includes the idea that fossils of extinct animals turn up where similar animals live today. Darwin came up with this theory when he discovered fossils of animals that were very similar to the animals that were living today. Darwin also observed that the Galapagos tortoise’s had different shapes of their shells depending on which island they came from. Darwin believed that these tortoises were adapting to their environment by changing their shell…

Charles Darwin provided a mechanism for the theory of Biological Evolution, which is what separates him from previous researchers. Before Darwin’s theory of biological evolution by natural selection, the ancient Greeks were the first to attempt to understand our place in the natural world. Following the Greeks, was Aristotle, he believed that each living form had attributes that could not be altered, therefore, fitting in an ordered rank ladder, and that human beings were at the top of the ladder. Before the 19th century most naturalist believed that there was a single creation event—influenced by the church’s beliefs (Stanford 17). Even then, naturalists continued to develop classifications for animals and plants. John Ray was the first to…

Darwin was not the first to suggest that life has evolved over time. In fact, there has been other researchers suggesting there theory. For instance, during 610-546 B.C. a Greek philosopher named Anaximander was one of the first to suggest that life-forms evolved from fish in the seas for this he went through a process of modification once established on land. Also, in the year 1735 Carl Linnaeus published his book, Systema Naturae in which he outlined a method for classifying all organisms. Darwin’s contribution was later acknowledged. Darwin’s most famous theory is called natural selection—stating evolutionary change derives through production of variation within generation and different survival of individuals with different [variation]…

Evolution is not suggesting that humans evolved just through chance, because evolution does not work by chance. Evolution is a much longer process and a change develops over many years. Evolution works through natural selection, which is also not a random selection or change. Although mutation occurs, which may cause random changes that may or may not be beneficial, evolution itself is not random.…
