Impact Updating Darwin Case Studies Applications Darwin & Cambridge Today For Kids For Teachers Natural Selection Natural selection is Darwin’s most famous theory; it states that evolutionary change comes through the production of variation in each generation and differential survival of individuals with different combinations of these variable characters. Individuals with characteristics which increase their probability of survival will have more opportunities to reproduce and their offspring will also benefit from the heritable, advantageous character. So over time these variants will spread through the population. Natural selection in the evolutionary framework: For natural selection to work, it has to occur along with a bunch of other things. Historians and biologists who have analysed Darwin’s work, for example Ernst Mayr, have identified five theories which Darwin outlined in On the Origin of Species, and which work together to bring about evolution. Darwin’s five theories were: 1. Evolution: species come and go through time, while they exist they change. 2. Common descent: organisms are descended from one, or several common ancestors and have diversified from this original stock 3. Species multiply: the diversification of life involves populations of one species diverging until...

...Charles Darwin: Darwinian Evolution 7/24/11 Professor A. Wagners SCIE 200 Assignment 4-1 Position Paper 4 Can a person believe in both, Darwinism and religion, at the same time? “We can do so only if we do not confuse evolutionary biology with a natural science and atheistic materialism,” (Junghyung, 2011). Darwin’s Theory of Evolution has been a widespread topic of disagreement for many decades. When his theory was first introduced in the mid 1800s there was controversy between religion and science. At the time Darwin’s theory was mainstreamed most Europeans were still firm in their belief of religion and that the earth was created in seven days by a divine being as described in the bible. “Darwin worked on his theory for 20 years. After learning that another naturalist, Alfred Russel Wallace, had developed similar ideas, the two made a joint announcement of their discovery in 1858. In 1859 Darwin published 'On the Origin of Species by Means of Natural Selection',” (bbc.co.uk). “The book was extremely controversial, because the logical extension of Darwin's theory was that homo sapiens was simply another form of animal. It made it seem possible that even people might just have evolved - quite possibly from apes - and destroyed the prevailing orthodoxy on how the world was created. Darwin was vehemently attacked, particularly by the Church. However, his ideas soon gained currency and have become the new orthodoxy,” (bbc.co.uk). Darwin’s theory that everything indeed evolved...

...What is evolution? Providing a definition of “evolution” is tricky because the word is used in different ways. First we need to distinguish between the broader worldview some associate with evolution and the scientific theory of evolution. The theory of evolution by natural selection, first formulated in Charles 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 behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring. The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism. Some of these characteristics may give the individual an advantage over other individuals which they can then pass on to their offspring. Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and...

...Theory of Evolution Charles Darwin was a British Scientist who lived from 1809 to 1882. He laid down the foundation of modern evolutionary theory with his concept of the development of life through the slow working process of natural selection. Darwin started to make notes about this theory in 1836 and in 1838 he had arrived at a sketch of a theory of evolution through natural selection. It was not until 1858 that his theory was first published in a paper. Darwin’s theory states that as plants or animals spread to new areas, or as the conditions change different variations would be favored in different places. This would mean these variations would spread through the populations of the plants or animals. Over time this would finally lead to a development of new species. This theory was explained in the book ‘The Origin of Species’, which describes his studies on the Galapagos Islands in the Pacific Ocean. He noticed that the species on the islands varied slightly from each island and were adapted to local conditions. The reaction to this theory was immediate. Biologists argued that Darwin could not prove his hypothesis. Others criticized his ideas of variation and how he could not prove how these variations came about or how they were passed on. This part of his theory was not answered until the birth of modern genetics in the early 20th century. In fact many scientists had doubts about this theory for 50-80 years. The most publicized attacks came from religious opponents who...

...ology Chapter 13 Lecture Outline Introduction Clown, Fool, or Simply Well Adapted? A. Review: Evolution is the central theme of biology. Evolutionary adaptation is a universal characteristic of living things (see Module 1.6). NOTE: More than any other idea in biology, evolutionary theory serves to tie the discipline together. T. Dobzhansky: “Nothing in biology makes sense except in the light of evolution.” B. If you look at any organism critically, you are first struck by the differences from other organisms. 1. Further observation often reveals that an organism’s features show some relationship to where the organism lives and what it does in its environment. 2. The blue-footed booby has enormous webbed feet, an oil producing gland that keeps the booby afloat, a nostril that can close under water that prevents water from entering the lungs, a gland that secrets salt from consumed sea water, and a torpedo-like body—all adaptations that make life on the sea feasible. I. Darwin’s Theory of Evolution Module 13.1 A sea voyage helped Darwin frame his theory of evolution. A. Awareness of each organism’s adaptations and how they fit the particular conditions of its environment helps us appreciate the natural world (Figure 13.1A). B. Early Greek philosophers held various views. Anaximander (about 2,500 years ago) suggested that life arose in water and that simpler forms...

...Artificial selection is a person deliberately chooses a male and a female with the desired traits and keeps them for breeding purposes. Over generations signify changes can occur in the species. Artificial selection is also known selective reading. This is the process of reading only the living organisms with desirable traits. This has been used by humans for thousands of years to preserve traits in pets, crops, and livestock. In hopes to produce offsprings from a certain trait. An example of artificial selection is a dog breeder might say he wants a dog that is all black he would then breed two black dogs. Using the artificial selection, of changes in organisms helped support Darwin's theory of evolution by natural selection. Natural Selection is the environment continually selects the individual best suited to it, the individual that survive gets to reproduce passing on their traits. Pros of natural selection is the variation of traits creating survival skills to fight off predators. However this process does have some flaw due to how long it takes to reproduce. Some examples of natural selection is if you were to move and you don't have a car you will have to adapt to a new system of transportation. Furthermore, artificial and natural selection share similarities as they both need each other to do their jobs. Using the natural selection species are draw to one another making artificial selection even possible. However, they have different traits that make them unique such...

...Session 1.3: The Evolution of Cellular Life Exam review view in a separate window In this session we focus on the natural history of cells and the evolutionary timelines of their appearance. The modern phylogenetic classification of domains is used to categorize the different types of cells: bacteria, archea, and eukarya. The names of periods and organisms and certain dates are often helpful in remembering or understanding events that occur in the natural history of evolution. However, we do not expect you to know the names of all organisms mentioned nor all dates (you may find some of the sound attachments on complicated figures useful for review). Those names and dates mentioned below are the ones to key on. The focus in this session is macroevolution which looks broadly at the time lines and changes over long intervals of time. Remember that small changes over millions of years are the framework for evolving complexity from simplicity. Summary of concepts and idea An initial step in covering this material is an understanding of the different types of cells (prokaryotic, eukaryotic animal and plant), their differences, and their place in the phylogeny of life. 1. Information from pre-class reading, Bioflix animations and briefly summarized in class discusses the fundamental components of the prokaryotic and eukaryotic cells. You need to know the differences and understand the basic functions of the cellular components as cells as they are the fundamental...

...Media Forms The theory of evolution from paper to the internet The theory of evolution must ‘evolve’ with the transforming media forms around it to maintain its scientific and social relevance. In other words, it must shift from the conventional media forms such as journals, books and publications and move towards the ways of the internet. Even collective groups of scientists and evolutionists can be shifted from physical to online gatherings via the ways of the internet and its related technologies. The majority of internet users throughout the world see the net as simply an enormous link-up of the world’s computers, after all, this is the ‘universal answer’ people tend to give when asked “what is the internet?”. Although this common answer is a pretty accurate image, it would be more correct to describe the internet as a “global network of hardware and software which stores and transports information from a content provider to an end user” . This infrastructure allows any person who wishes to say anything, access to say it to the world. Controversial topics are abundant on the World Wide Web, and this media form enables these topics to be discussed, investigated, or challenged. Evolution is defined as being: “A gradual process in which something changes into a different and usually more complex or better form”. Arguments for evolution include The Fossil Record, Darwin’s theory of Natural Selection, and Biological Evidence. Arguments against evolution include The Second...

Green beetles are selected against by natural and Brown beetles are selected for- so they reproduce more) *Adaption: A trait that increases the ability of an individual to survive and reproduce compared with individuals without the trait Adaption in an evolutionary context: An inherited trait that makes an organism more fit in its abiotic and biotic environment, and that has arisen as a result of the direct action of natural selection for its primary function. Ex. Mimicry of the non-toxic king snake to evade predators Natural selection leads to Adaptions * Adjustments or changes In behavior, physiology...

...Design Arguments St. Thomas Aquinas was an important theologian and philosopher whose work on the nature and existence of God and his arguments for a moral code based on the ‘natural law’ God has instilled in the universe have formed the central teachings of the Roman Catholic Church. He sought to bring faith and reason together in order to develop the place of theology in the world. The argument from design finds its origins in Aquinas’ Summa Theologica and is the fifth of his five ways of proving the existence of God. Aquinas’ argument can be explained as follows: “The fifth way is taken from the governance of the world. We see that things which lack knowledge, such as natural bodies, act for an end, and this is evident from their acting always, or nearly always, in the same way, so as to obtain the best result. Hence it is plain that they achieve their end, not fortuitously, but designedly. Now whatever lacks knowledge cannot move towards an end, unless it be directed by some being endowed with knowledge and intelligence; as the arrow is directed by the archer. Therefore some intelligent being exists by whom all natural things are directed to their end; and this being we call God.” Aquinas argued from design qua regularity. He saw the overall order in the world as proof of a designer: ‘this being we call God.’ Aquinas stated that everything works together to achieve order, despite the fact that inanimate objects have no mind or rational powers to achieve...

...expected to believe that there is a God and we never question if he exists or not because the bible is all the proof we need. Since I was 16 years old I always wondered if there was really a God and if so, where is he when you need Him the most and what is the big deal with this Evolution thing? I always had more reason to believe that Evolution makes more sense and has more concrete evidence than believing in a God you cannot see or do not have much or any other evidence that he really existed other than the Bible. Argument: Is there a God? Personally I think there isn’t, and the Bible makes it sounds like if you do not believe in him you automatically go to hell! However, a good person who does the right thing most of their lives but does not believe that God exists makes them what Christians call: “Devil Worshippers”, and is sentenced to hell forever? That doesn’t sound like a God who cares much about his people on earth, but more about himself, to have a lot of people sent to the burning pits of hell because they do not believe in him although they may do the same thing as what a Christian may do, but the only difference is the belief system. A lot of horrible people go to church every Sunday, but they may go to heaven if they repent their sins. How can God forgive a murder or a rapist and give them a second chance, but make children and innocent people suffer every day? Does that sound like there is a God, because to me it seems like there isn’t one and he is something...

...understand how most of mankind is playing out a story that will eventually destroy the world, while a small minority of people live in communion with the community of life and can lead to an eventually brighter future. Ishmael teaches about captivity, identity, and evolution in the forms of “takers” and “leavers” (140), as well as “mother culture” (20) and “civilized peoples”(22). The first name that was given to Ishmael was Goliath, which makes him more self-aware of his personal identity, but a name is only a name, and not one's whole identity like names so often force onto someone. He teaches that we do not need to accept the identity that we were born with, but can make our own destiny. Names are just another way for “mother culture” to imprison people in her game. Ishmael was raised in captivity and it is what he considered to be his “area of educational expertise” and...
