All of the mechanisms of evolution were present in both simulations. Natural selection was present due to the fact that the environment was selecting for specific traits. In Addie’s case, the resistant bacteria was being selected for by Addie’s body. In the Mt. Laguna and UCSD birds, the boldness behavior was being selected for in the city. Migration leads to isolation in both simulations as well.…
In George Mivart’s ‘Genesis of Species’, Mivart thoroughly reviews Darwin’s theory of natural selection. Mivart concludes that Darwin’s theory of natural selection is flawed because it cannot account for all of the mechanics of inheritance, specifically the initial developments of useful characteristics. He disputes that natural selection can account for the passing of negative or unnecessary traits, or for individualized traits occurring in only one species. He also asks how certain developments could occur without saltations, an idea absent in Darwin’s theories, but prominent in many of his contemporaries’. To illustrate these issues with natural selection, Mivart uses giraffes, insects that mimic other things in nature, fish, kangaroos, and whales as examples, which I will summarize below.…

5. Emerson makes many of his points through a series of figures of speech - comparisons between two things that are basically unlike. In "Self-Reliance" what does he compare with the ordinary things and events listed below. Be sure to respond in complete sentence format.…
In an essay published in 1841, Emerson addressed one of the central characteristics of the American sensibility: individualism. Before you read, take a moment to think about the term “self-reliance” and what it means to you as a teenager and a student. As you read, determine what “self-reliance” meant to Emerson and how your meaning and his overlap.…

Weiner has the advantage of being able to compare and contrast Darwin and the Grant’s by building chapter three like a sandwich. The reason for Weiner’s strategy was to give expert testimony to back up the idea of evolution. He used research from different biologist in different times, and their statements supported each other.…
Evolution is and ongoing process of change and diversification which every scientist to this day accept as a historical fact. However, evolution is a very controversial subject worldwide. There are many studies, theories, and opinions regarding how we became to be, including every living creature and human being, the universe and everything else that comes along with it, and especially how our planet Earth transformed into what it is today. Phyletic gradualism and punctuated equilibrium are two very controversial and debatable theories/concepts that have brought up lots of questions, opinions, and answers. Gradualism and punctuated equilibrium are two different concepts that seem to intertwine along each other’s path. In this IP 2 I will explain both theories.…
This separation of the river is described as a gradual change in which species came into their beings, which took place over a long period of time. Dawkins mentions in Chapter one that the river that he is referring to is that of DNA, “flowing through time” (Dawkins 4). He describes the river as being full of information and instruction on evolving, an abstract manual on the creation of species. With this being said, it can be seen that Chapter 1 and 3 are complements of each other and are able to support points made in each chapter. Evolution is gradual, as discussed in Chapter 1, further solidified in Chapter 3. Each generation of organisms is a sieve against which replicated and mutated genes are tested, a process that is not only gradual, but one that happens over time. Organisms become better and better as time goes on and are able to build off of what has happened in species before them. “Ancestors are rare, descendants are common,” meaning that good genes make successful organisms, which perpetuate good genes themselves (Dawkins…
Dualistic Interactionism are one of the many theories that argues that two elements, which is the body and mind are separate yet have some sort of connection or interaction with each other. From what I believe, I do understand and accept the fact that we do have a physical body and that we do have a mind that is not physical, but I have a hard time justifying the concept that the mind and body are two different entities and then the body and mind can really interact with each other. I think the reason being for that is because there are so many crazy theories that are against this one and vice versa. But after reading about some of the concepts regarding dualism in Chapter 5, I can somewhat support some of the points that this theory does…
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.…
Natural selection is the driving force in evolution because it is what trait offspring. There are many cases of evidence showing this such as the peppered moth population, the blue mussels, and the finches that we studied.…
When the phrase “A, What’s More B, comes to mind one may quickly think of the word parallelism.” Parallelism is the joining together of related ideas to form a complete thought” (Fields, 2008). Additionally, parallelism relates to the written communication between the phrases of poetic lines which are found in certain books of the Bible. Many examples of parallelism are found in the books of Proverbs and Psalms. When one completes a parallelism it is then referred to as a line. Each of these lines must include at least two or more poetic phrases and or colons.…
Explanations of how these findings impacted the developing theory of evolution and relate to the modern theory of evolution: He came up with the theory of punctuated equilibrium which explained that evolution didn't occur at a constant rate but it brought him into conflict with other evolutionary biologists such as Richard Dawkins. Punctuated equilibrium is now widely accepted as being a valid explanation for apparent gaps that had appeared in the fossil record. It still involved a process of natural selection so it didn't contradict Darwin's original theory.…
