Assignment 3:
According to the dictionary, evolution is defined as the process by which different kinds of living organisms are understood to have not only developed but diversified from earlier forms during history. However, according to the course materials, evolution is defined by Charles Darwin differently. Darwin came up with the idea that maybe all species change over a period and during that time not only do some of the species evolve, but some also stay the same and others change dramatically. This is occurring due to the process of natural selection. What is natural selection? There is a group of species in a population who are accustomed to the different aspects that occur, such as environmental change. The individuals from that group of species who are the most adaptable to the rapid changes are the ones who have an advantage over those who are not as well suited. The truth is, many may think that individuals may evolve such as a deer might evolve on its own to the changing environments. However, for the deer to evolve to the surroundings it needs support. The deer needs help, it needs a support from a family to properly evolve because it can’t evolve on its own but in a group. Within a population, such as a deer population, the deer will vary in size, structure, sex and personality. Due to these variations within the deer population, the other species within the population can survive better. Additionally, the species can reproduce in favorable environmental conditions which produces a higher survival rate and more offspring to the new generation after them. An interesting aspect of anthropology is the fact that Physical anthropologists can investigate evolution.
According to Google, physical anthropology is defined as the branch of anthropology concerned with the study of human biological and physiological characteristics and their development. Paleoanthropologists is a good example of an aspect of physical anthropology. Paleontology examines as well as investigates the process of evolution by studying extinct organisms or fossils. The extinct carefully thought out studies help better examine the evolution of humans. Several important aspects are studied, such as reproduction, anatomy, and physiology of these individuals. A good example of outside source identifying one research project in which physical anthropologists are studying evolution is, "New Genome Comparison Finds Chimps, Humans Very Similar at The DNA Level" During this research project, physical anthropologists are studying prehistoric evidence of monkeys and the biology/genetics of living humans. During this study, 67 types of researchers took part in the Chimp Sequencing and Analysis Consortium. Collins discovered, "The researchers discovered that a few classes of genes are changing unusually quickly in both humans and chimpanzees compared with other mammals. These classes include genes involved in perception of sound, transmission of nerve signals, production of...

Evolution and Charles Darwin´s Natural Selection

830 words - 4 pages the fact of where we came from, or at least, science's theory about it. Darwin's theory of natural selection is a very big part of evolution, showing the gradual adaptation of characteristics in species. Natural selection is the gift of new beneficial adaptations to animals of a species, for the purpose of survival. The good traits are kept through the survival and reproduction of animals with the traits. The bad traits will be eliminated

They were all many different shapes and colours. Darwin knew that they were all from the same species so he realised that animals or plants from the

Darwin´s Theory of Natural Selection and Primates

1400 words - 6 pages brewing debate over the early theories of evolution came the most compelling theory by Charles Darwin. Darwin explained the variation in species through natural selection, which was the core of his theory of evolution. The realizations about natural world provided the context for Darwin’s theory of evolution. His theory was supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and

Evolution and Natural Selection

620 words - 2 pages the plant genetic polymorphism heterostyly. Beginning with the pioneeringwork of Charles Darwin, evolutionary biologists have been fascinated with how heterostyly hasevolved and how it functions in plant populations.The polymorphism has evolved independently in approximately 25 Angiosperm families.A final example of natural selection involves the evolution of long floral tubes in mothpollinatedflowers. Work by the Swedish pollination biologist L. Anders Nilsson has resolved a long-standing controversy concerning the pollination biology of rare Madagascan Orchids with extremely long floral tubes.

Natural Selection and Phenotypic Variation

2025 words - 8 pages Long standing arguments against the theory of natural selection stem from the occurrence of incipient structures and complex traits in organisms despite the seemingly stochastic nature of mutations. Many complex adaptations observed in nature today are thought to have arisen from less complex ones with simpler functions, therefore these characters are thought to have been “pre-adapted.” In order to go from a simple to a complex structures

Natural Selection, Scale, and Cultural Evolution

956 words - 4 pages In his article entitled “Natural Selection, Scale, and Cultural Evolution” Dunnell states that his purpose for the paper is to explain why evolution has made such a small impact on archaeology. His hopes, he says, are to give ways to integrate evolutionary characteristics and anthropological theory effectively. He first explains that cultural evolution and biological evolution are not the same (1996, pg 24). Because its “laws are not

Natural Selection, Scale, and Cultural Evolution

985 words - 4 pages Evolution can be seen throughout all aspects of life, but for each aspect evolution does not occur in the same process. In his article entitled “Natural Selection, Scale, and Cultural Evolution,” Dunnell emphasizes and explains why evolution has made such a small impact on archaeology. Cultural evolution and biological evolution are not the same. Biological evolution uses theoretical propositions that explain the mechanisms of biological

Darwin’s Theory of Natural Selection and Social Darwinism

562 words - 2 pages book, On the Origin of Species by Means of Natural Selection. Darwin decided it was possible for a species to change from one form and develop into another over time. This led him to the notion that all life forms were not fixed, but continuously changing or evolving. The other part of the theory was that living things weren’t the result of many separate creations, but of long, intertwining biological histories. His general idea was that

Darwin's Theory of Natural Selection and the Evolution of Animals

953 words - 4 pages heighten their abilities to survive, to get food and most importantly to reproduce and all of this is a result of the process of Natural Selection. (Eg. If only fast moving prey survive then that species should evolve over the generations in the direction of becoming on average faster moving.) Darwin believed that the increasing competition for finite resources exerts selective pressure because those who lose, when

What is evolution and what is natural selection?

It was after his joint presentation with Wallace that evolution really began to gain widespread acceptance in society. In his book "Origin of Species" Darwin proposes a two-part argument to support his evolutionary theory, 'Struggle for Existence' and 'Natural Selection'.The 'Struggle for Existence' argument proposes two

Darwin’s Theory of Natural Selection and Social Darwinism

1232 words - 5 pages In 1859, a biologist named Charles Darwin postulated a scientific theory, which stated that all living organisms evolved through a process of natural selection. According to Stephen Hawking, Charles Darwin claimed that the offspring of a particular species gradually evolved themselves genetically to resist the changes in the environment (573). The theory contended that the organisms could adapt to the changes in the environment through

And then, he wrote the theory of Natural Selection:         One of the prime motives for all species is to reproduce and survive, passing on the genetic information of the species from generation
