The 2001 film “Evolution”, is an entertaining film about an alien species being introduced to earth via meteor. However, this film seems to contain a copious amount scientific inaccuracies. For example, when the meteor is traveling through space, the movie presents the meteor rushing towards Earth with sound. However, space is a vacuum, so there for there would be no sound in space.

Over the last several years, evolution has been playing an increasingly important role in determining how various species are evolving. This is because ecology will have an impact on how quickly a particular organism is able to adapt (with: the unique challenges for a particular environment). To determine the effect that this is having requires carefully examining different species over the course of many years. This will be accomplished by comparing these changes on Darwin and Wallace Islands. Once this occurs, is when specific insights will be provided that are highlighting the underlying challenges affecting the development of organisms. This is the point that these transformations will be evident among the various life forms. (Fasolo, 2011, pp. 53 68)

According to Ms. Witsaman, evolution is not the theory of how life began, which is a common misconception nowadays, but the theory of how life has changed over time. Theories are predictions which are backed up by several evidences and supported by scientists. The evidences that scientists use now to prove include fossils, homologous structures, analogous structures, vestigial structures, embryology, biogeography, and biochemicals. Fossils are the remains of living things that once roamed the Earth. Homologous structure are structures shared by different organisms that have similar structure but different functions. Analogous structures are the opposite, they have similar functions but completely different structure.Vestigial structures are

“The main lesson of biogeography is that only evolution can explain the diversity of life on continents and islands.” (Coyne 109).In convergent evolution 3 of the six components discussed in chapter 1 are working together. These 3 components are common ancestry, speciation, and natural selection. If evolution did exist, ancestors of species today that lived in the same place, when dug up, should be fossils that resemble organisms today.

continuation in producing very high amounts of corn and different corn products which has only added to the corruption of the nitrogen cycle but also the agricultural system which has only negatively impacted the American diet. Pollan continues to support his claim of how the government supports and benefits farmers for their corn by bringing up that the US Department of Agriculture pays nineteen billion dollars to farmers each year for their continuation in the production of corn.

Over time, it evolved into a huge family of more than fifty species. You'll get clues to how it happened as you explore the natural selection of fictional pollenpeepers in this activity.

The process of evolution by natural selection begins with the overproduction of offspring, continues with the variation of these offspring, then the selection of the offspring that best fit the environment, and finally, the acclimatization of these offspring to their surroundings. While these steps don’t necessarily have a concrete duration of time in which they take place, the process follows this general pattern. Overproduction is necessary to be able to select from the most “suitable” or “fitting” offspring from a sizeable group. The three or so steps following overproduction coincide with one another and are necessary for the adaptation of offspring in an environment.

Human trait mismatches are a state of imbalance when a characteristic that developed in a particular environment becomes not adequate in another setting. This type mismatch is an essential aspect of evolution in adjusting to environments and is turn out to be increasingly widespread for all species subsisting in human transformed surroundings (Eadie, 2016). It is particularly important to comprehend mismatch in connection to our specific species, because hominids have so drastically transformed their own circumstances and disparities can transpire for cultural development furthermore to the genetic evolution.

Domestication is a phenomenon that has promoted significant evolutionary change under strong selective pressures (Driscoll et al. 2009). As a result of this phenomenon, various domesticated strains of flora and fauna have significantly contributed to the development of human civilization (Morey 1994; Driscoll 2009). Although it was a substantial component to our progress, it was not until the research of Dmitry K. Belyaev that we began to unravel the early stages of domestication. Assuming that these initial stages involved selection on behavior, Belyaev conducted an experimental study that placed strong selective pressures on tamability. Using the fox, Vulpes vulpes, as a model, this artificial selection developed an experimental population that expressed behavioral, morphological, and physiological characteristics of domesticated species (Belyaev 1969).

Although modern evolutionists are thought to be divided on the issues surrounding evolutionary theory, a close look at the evidence suggests that both the gradualist school of thought and the punctuationist school of thought share many characteristics in common. This is especially true when evaluating their beliefs about the fossil record, disagreement with the theory of saltation, and the misinterpretation of the word “rapid” in terms of punctuationist theory. Although this may be the case, the two theories do diverge on one important point, the notion of periods of stasis, but when taken as a whole, the evidence suggests that punctuationism is not as radical as it has been hyped up to be.

Non-historical definitions of adaptations are more useful for modern interpretations of adaptations. Gould and Vrba’s hypothesis finally addressed the origin of the adapation and claimed “an adaptation was a trait whose “historical genesis” was due to the same selective pressure as that which currently maintains the trait.” An adaptation which no longer had a selective pressure was named an

There are many ways to explain how Earth and everything else came to be. Such as, Uniformitarianism, Catastrophism, Gradualism, and Punctuated Equilibrium. Generally, Uniformitarianism and Catastrophism are grouped together while Punctuated Equilibrium and Gradualism are grouped together separately from Uniformitarianism and Catastrophism. Gradualism and Punctuated Equilibrium are usually looked at through a biblical stand point rather than how Uniformitarianism and Catastrophism are looked at from the opposite view.

How did this historical evolution unfold? In the late 1960’s, capital movements began to undermine the Bretton Woods preoccupation with capital controls, as US officials began actively encouraging the growth of the Euromarket— the pool of unregulated dollar reserves concentrated in the City of London. Speculative capital flows, however, began to undermine the capacity for the US to guarantee the convertibility of dollars into gold at fixed parity (Triffin, 1960). In 1974, Nixon closed the gold window and loosened capital controls. The deregulation of financial markets established a global market of mobile financial capital, yet Keynesian inspired institutional arrangements remained intact, especially the maintenance of cheap money policy for

Evolution occurs when an animal species develops new bodily structures and functions in order to adapt to their new environment. These developments are seen as positive adaptations that enhances survival. However, some animal species have lost these new developments. Based on the geographic location and climate, some evolutionary developments that are no longer needed are lost due to the fact that the new bodily structure itself does not enhance the chance of survival in a particular environment (Kirchman 2009; Vieites, et al. 2009). In most cases these lost developments are passed down through future generations and are never redeveloped. However, more information is needed to decide whether or not the loss of these evolutionary developments was due to natural selection or by random mutation over years (Wilkens and Strecker 2003). In this paper, I will examine three studies from a diversity of taxa, which illustrate the history of flightless birds, how climate has influenced the evolution of salamanders and how life lived in darkness has influenced the blindness in cave fish. Together these studies depict how these evolutionary abilities are lost and their affects on the animal species.
