Rapid Evolution Changes Species
The article “Rapid Evolution Changes Species in Real Time”, written by Jane Braxton Little, is a controversial look at evolution. This article presents a clear thesis, Little, along with scientist David Reznick, both believe that the process of evolution can be sped up. The process of evolution is due to environmental conflicts or possibly created by man. Throughout the article Little consistently focuses on her main thesis, and provides multiple examples to help back up her claims. Reznick states “I was hanging my career on the idea that you could change the environment and see things evolve significantly in time to get tenure”. He tested Trinidad guppies and placed them in two different environments, one set in a stream with predators, and the other in a stream …show more content…
The language in this article is partially appropriate for the general public, sometimes the author uses particular vocabulary that may be difficult to understand. I assume if people find themselves reading this article, then they will already have some background knowledge about the subject. An example of difficult vocabulary in the article is “Topographic”, and the author does not later define. Besides that term the rest of the vocabulary. I do believe that the author uses terms to seem more authoritative, and I think the author is trying to create a bias to make the reader feel the same way about the thesis. It is difficult not to agree when she backs up her thesis with concrete examples. Little believes that these scientists help prove that rapid evolution changes species. All of the examples provided by the author are relevant to the thesis and all support the thesis as well. The article has illustrations, but they do not help prove the thesis. They do give the reader a good look at a scientist (Reznick), Trinidad guppies, a Green Anole lizard, and a diagram of

    Next, Russow provides objections to three traditional arguments for why species do matter. The first is the argument for stewardship which Russow dismisses due to its assumption that species are valuable. The second is the argument for extrinsic value of species regarding their contribution to big picture of life. Russow objects to three different extrinsic value perspectives by 1) stating that we cannot use a specie’s declination as a sign that humans are doing something wrong because that cannot account for unforeseen events, 2) stating that not every species is required for ecological stability, and 3) denying the evolutionary chain argument because…

    Possums, from populations with exposure to this vegetation, are particularly tolerant to fluoroacetate. However, the level of tolerance varies among the different populations of each species, depending on the degree to which the toxic plants were present in their microhabitat. The brush-tailed possum (T. vulpecula) from Western Australia was found to be nearly 150 times more resistant to fluoroacetate intoxication in vivo than the same species from South Australia. Both possums are capable of de-fluorinating fluoroacetate at similar rates by a glutathione-dependent enzymic mechanism resulting in the formation of free fluoride ion and S-carboxymethylcysteine. Glutathione was also capable of partial protection against the toxic effects of fluoroacetate in vitro by a further unelucidated mechanism.…

    In the 1970s, an investigator named John Endler traveled to Trinidad in the 1970s to study wild guppies. The guppies live in small streams that flow down the mountains from pool to pool. The experiment will take part on an online simulation of Endler's work. The group of members is responsible for collecting data, formulating a hypothesis, and running a series of experiments. They will find out about the interplay between natural selection and sexual selection in this wild population of guppies. They will ultimately find out the effects on the guppy population and their color distribution depending on the predator that lives in their environment. Endler wondered how the trade-off between attracting mates and affecting predators affects the coloration in male guppies. In pools that had few predator species, male guppies tended to be brightly colored, whereas predators are causing guppy populations to become drabber. This occurs because the predators are preying on the most brightly colored individuals and eliminating them from the gene pool. Therefore, guppy populations are evolving to more closely match, or stand out from their environment. Endler hypothesized that intense predation caused natural selection in male guppies, favoring the trait of drab coloration. He further tested his hypothesis by transferring brightly colors guppies to a pool with many predators. As he predicted, over time the transplanted guppy population became less brightly colored. Females tend to look for the bright colored male guppies in the pool and mate with them. This enables those males to have a higher probability of passing their genes on to their next generation. In the simulation, predators can dramatically influence the evolution of a population of guppies, but change does not occur quickly during the testing of one generation for each trial. (Before columns on graphs in the Data section of the simulation report) Scientists believe that they see changes in just a few…

    When hearing the word extinct, the first thing that tends to pop into everyone’s head is dinosaurs. The common belief is that in order to see these amazing creatures and other extinct animals such as the woolly mammoth and the dodo bird, we watch movies such as Jurassic Park and Ice Age, and for a more personal connection with these creatures, we go to theme parks or amusement parks and museums for a glimpse of what these incredible creatures were like. There is also much more abundance of extinct animals that no one has ever heard of, but are some of the most beautiful, and the ugliest, animals to ever exist. However, after years of research and weather changes, visiting these magnificent creatures may be much more than your average trip to the local movie theatre or museum.…

    After spending time on the Galapagos Islands studying the origin of various species, former divinest Charles R. Darwin proposed the evolutionary theory of natural selection, a mechanism by which advantageous variations in a population are preserved while unfavorable variations are lost (Berkeley, 2008). As a result of these variations, some individuals are better acclimated to their environment than others. This results in the better-suited individuals outcompeting the less fortunate individuals for resources, and eventually causes genetic types to replace others. Natural selection is ultimately a process that can lead to the evolution of species (Zimmer, 2013).…

    The first few theories were impressive enough to hold onto the reader’s attention but soon after when the author jumps from one topic to another, it becomes hard to follow. Although the essay was written over twenty years back it asserts the up to date information. The author is more of an informative person rather than persuasive and most of his claims are supported by facts and research. The author has definitely done his own study about the topic before writing about the extinction. The way of portraying the whole essay was very impressive and organized.…

    He expressed this theory through the idea that animals and various primates partake in the act of natural selection. In 1997, the National Science Foundation (NSF) supported Darwin’s theory by gathering a research team together and running a serious of studies that demonstrated “that animals can adapt to sudden changes in their environment with surprising speed” (Dybas, Chery 1). Researchers Frank Shaw and Ruth Shaw of the University of Minnesota, St. Paul, and F. Helen Rodd of the University of California used wild guppies from the West Indies island of Trinidad and found that “fish that were moved from a predator-infested pool to a pool with just one predator grew larger, lived longer and produced fewer but larger offspring. In the span of seven to 18 generations--between four and 11 years--they became more like the native guppies in the relatively predator-free environment” (Dybas, Chery…

    Greed is a capital sin, but many businessmen do not care about that in order to raise their profit. Thus people who earn money by hunting animals always aim at the biggest and most superb ones. By looking at the nature, one can recognize that the predators usually take either the very young or the weak animals. First it sounds like an insignificant difference, but the effect of it is disastrous.…

    Since the time of Darwin it has been recognised that biological species are essential to the process of evolution. A species consists of a population rather than unconnected individuals. The population of any species is reproductively isolated from that of others because of the fertility criterion. This means that despite the cohabitation of similar species in a specific territory no interbreeding will occur. Mayr states that ‘Each species is a delicately integrated genetic system that has been selected through many generations to fit into a definite niche in its environment. ' Palaeontology, according to Darwin, accounted for the formation of any new species through a gradual transformation of the ancestral population with large numbers of individuals in the inhabited territory. Eldredge and Gould later named this process phyletic gradualism. This phyletic gradualism, however, continued the tradition of extrapolation from local populations and also used the accepted model for adaptive geographical variation, namely the gradual substitution of genes directed by natural selection, as a paradigm for the origin of species . This theory, as Mayr argues, does not take into account the advantage of the isolate. Mayr recognised that speciation occurred more rapidly and more effectively in small, isolated populations. That is populations that have migrated from the larger ancestral population and therefore are isolated from the homogenizing effect of the gene flow. In this way successful speciation occurred due to the cumulative effects of small variations over a number of generations. This process is more commonly known as evolution.…

    Natural selection takes the raw material of variations with a population and moulds it over a long period of time into a population that can compete most effectively with other species. This selection will favor the fittest individuals in a species to fit a particular biological niche. Any given environment will have a large number of niches, for example small variations in the temperature, humidity and exposure to sunlight will affect the ability of certain plants to grow and compete with other plants. Species that fit these niches will represent a very diverse population and therefore will have extensive genetic diversity. This diversity will be both at the level of an individual species and also at level of different species which co-evolved to fit a particular biological niche. Within a niche there are numerous different solutions to the problem of adaptation to that environment, and it is likely that different species will develop different methods of adaptation that enable them to survive in any particular niche. In summary, natural selection will drive the adaptation of any given population to fit the number of available niches, and this will create the biodiversity that is present in nature.…
