Explain the adaptive value of female body shape as it relates to evolutionary theory. Remember to include details that are missing in the media article (e.g. explain other features such as waist and hip ratio).

This paper discusses the theory of evolution in detail. Topics this paper will address include defining the theory of evolution and explaining how the theory has evolved over time, as well as highlighting the strengths and weaknesses of the theory and examining how effective the theory is in today’s world.

A scientific theory is an explanation of an aspect of the world, based on facts that have been frequently confirmed through observation and experiment or is often just speculations. Is evolution just a theory? Evolution is considered a valid scientific theory as it cannot be expressed in a concise mathematical equation so it is referred to as a theory, which does not make it more accurate than a law. Natural selection, comparative embryology, comparative anatomy, DNA and scientific contributions all support the theory of evolution.

What does it mean to be human? Is humanity defined by our biology or our morality? Some combination of the two? Or, is it merely the ability to ask this very question, or ones exceedingly similar in form? Darwin’s The Descent of Man attempts to provide a foundational understanding to how we all got to where we are, and what our origins might say about our present. In particular, the way in which evolution is applied to various species, natural selection, is said to dictate which members of a certain species survive according to their proclivities determined by genetics. A natural question to arise from the assertions of the theory of natural selection is how this applies to humans now. It’s not as if one could kill their boss in order to

In order to understand evolution and natural selection you have got to know where it came from and how it came to be. First, let’s go all the way back to two of the four most commonly known, and most important, natural historians that encouraged the belief of an evolutionary process. Georges Buffon was a French naturalist during the 1700s. He was one of the first to reject the idea of a 6000 year old Earth. Instead, he believed it had to be much older. Buffon also proposed the idea that species did not arise separately, but rather shared common ancestors. Jean-Baptiste Lamarck, who was also a French naturalist, did not think that species became extinct, but that they evolved into different forms. He thought that changes in the environment triggered this evolving into different forms and that the evolving into different forms caused either a greater use or disuse of a structure. Both of these

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).

Evolution is the process in which organisms descend from ancestors. Evolution is responsible for some of the various similarities seen through biological life, and it also explains all of the diversity in organisms and species. There are various components of evolution: descent, mutation, natural selection, genetic variation, genetic drift and coevolution. All of these components are extremely fundamental to evolution because Darwin's theory of evolution states that all species and organisms have arisen and developed due to material stemming from natural selection of petite inherited variations that can increase the ability for said organism to survive, reproduce, etc. This theory states that the changes that have occurred through mutation is beneficial, harmful, or neutral. If changes in an organisms DNA is harmful then the odds of that organism surviving/reproducing/ etc is unlikely. Some may think of this concept as survival of the fittest. Mutations tend to make the evolution process speed up which means that new genes are added to a species' gene pool. This is beneficial to an extent when it comes to organisms that have many dangerous genes and factors that can cause their offspring to mutate and continue to reproduce organisms with less than mutations. Those who are deemed

Even though evolution is an ancient concept, Charles Darwin brought up a new idea focusing on naturalistic modification of a population over time. He believed that species differ over time and space. In other words, after a period of time creatures undergo genetic mutations in their genetic code in which the beneficial mutations are preserved and the disadvantage mutations are eliminated. This concept he termed as natural selection. According to natural selection, all species have common ancestry and their diversity comes as a result of descent modifications. A species that develops functional advantages would pass the same traits to their offspring

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.

The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in 1859. It is when an animal changes over time it changes its heritable physical or behavioral traits. This happens so a species is better suited to live in an environment and to have more offspring. Evolution by natural selection is one of the best substantiated theories in the history of science due to is evidence from paleontology, geology, genetics, to developmental biology.

No man has been as influential in the history of evolutionary science as Charles Darwin, a prominent British naturalist, geologist and botanist who came to solidify himself in these fields of studies in the nineteenth century. In 1831, Darwin embarked on a British government-sponsored voyage on the HMS Beagle to the coast of South America and several remote islands in the Pacific, where he closely observed the landforms and natural species that were native to these parts of the world, which he had never encountered before. Upon confronting these previously unidentified species, he made numerous observations, took copious notes in his journals and collected meticulous samples on these islands. The voyage lasted for five years, and upon

“Survival of the fittest” is one of the greatest concepts discussed by Charles Darwin (who is known as the father of evolution) and which has also affected many species throughout the world over the years, including us! As presented in his theory of evolution, Charles Darwin explains how those with advantageous traits will be able to better survive than their fellow counterparts. In other words, organisms with traits best suited for their environment will have higher chances of surviving than those without those certain traits. According to The Living Environment Holt textbook it states “For example, he suggested that all of the finch species descended from one ancestral finch species that migrated from South America. Then, the descendant

In 1859, Charles Darwin published On the Origin of Species, introducing the theory of evolution. One hundred and fifty-six years later, scientists still accept this senseless philosophy. House Majority Leader Tom DeLay states, “Our school systems teach the children that they are nothing but glorified apes who are evolutionized out of some primordial soup” (Snyder). Schools worldwide have presented exactly this to the young, impressionable minds of your future doctors, engineers, scientists, and presidents. They assure us that if we give a small amount of mud enough time it can, by itself, bring about the art of da Vinci, the plays of Shakespeare, the music of Mozart, and the brilliant mind of Einstein.

The study of Evolution has been a hot topic of controversy over the last two centuries. The definition of evolutionary biology itself generally refers to an area of biological study mixed with the study of the evolutionary processes that are produced by the diversity of life on Earth. This tour of centuries ago, the one you are about to take will help you gain a better understanding of not only those who have influenced the theories of evolution, but also a few pieces of evidence of evolution that help support the theory itself.
