Essay on Varying Patterns of Speciation

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)

As seen with Anolis, single species of organisms have the ability to undergo adaptive radiation and become new species by filling niches in a given environment. This is prevalent not only in Anolis, but other model organisms as well, such as finches, sticklebacks, and cichlids. All of these organisms have gone through the similar mechanisms and processes to evolve into different species. Alike to Anolis, they have gone through reproductive isolation, adaptation, and convergent evolution. Due to a poor fossil record of Anolis, the other model organisms may give better outlook on how they have diverged overtime. Further investigations on all of these organisms and their evolutionary mechanisms would not only give better a better idea of ecological speciation, but more comprehension on the origin of all

The aim of our excursion to Hastings Point, New South Wales was to study the biodiversity and ecology and to see how these organisms behave in their natural habitat and surroundings. There will also be information collected about a variety of different organisms as well as population counts and observe how they have adapted to the species surrounding environment. The excursion will also be an opportunity to gather information on

Phylogeography is a field of study that implements biogeography and genetics to understand the geographic distribution of a species. It is concerned with historical principles and processes that influence evolution and speciation. The tiger is an evolutionary wonder; it is a prime example of the responsiveness that some species have to changing climatic conditions. The tiger once had the largest geographic distribution of all cat species; subspecies adaptations allowed them to live in a large range of habitats throughout the Asian continent making it a perfect candidate for the study of phylogeography. This review will examine the evolutionary history of the tiger and will explain how the species was affected by climatic fluctuations and biogeographic processes during the Plestocene epoch.

Propose reasons for the evolution, survival and extinction of species, with reference to Australian examples.

Lyell convinced Darwin to publish his theory before someone beat him to it. Darwin started to write a detailed book about natural selection. While Darwin was writing his book, he was still in Malay Archipelago and was sick so he spent his time writing a detailed essay about natural selection and only the fittest animals will survive and sent it to Darwin for both of them to check his work. Lyell and Hooker went behind Darwin and Wallace’s back and took Wallace’s paper and two of Darwin’s papers about natural selection and presented them to a meeting of the Linnean Society of London where they were published together and Darwin would earn the most credit for the work. Wallace did receive some credit for natural selection, which still remains the primary explanation for adaptive evolution. Wallace not only created the theory of natural selection he came up with “Wallace Line” which extends between Bali, Lombok, Borneo, and Sulawesi. The line marks the limits of many Asian animal species to the east and limits western extent of Australian animal species (Beccaloni, Smith

The ongoing scientific investigation of how exactly evolution occurred and continues to occur has been an argumentative idea amongst society since Darwin first articulated it over a century ago. The scientific basis of evolution accounts for happenings that are also essential concerns of religion; both religion and science focus on the origins of humans and of biological diversity. For instance, in the reading “Truth Cannot Contradict Truth,” Pope John Paul II, addressing the Pontifical Academy of Science, discussed the matter of God as creator of man. The Pope explains that men cannot relate to animals because men are superior. The reasoning for that is because God created humans under his likeness. What the church is saying about mankind

From the common ancestor to organisms as complex as the Bonobo, certain species have changed to the point where they cannot be seen as related to their ancestors at all. The Bonobo (Pan paniscus), the Emu (Dromaius novaehollandiae), the domestic Dog (Canis lupus familiaris), the Rhinoceros (Rhinocerotidae), Blue Whale (Balaenoptera musculus), Lion(Panthera leo), and American Crocodile (Crocodylus acutus) are all prime examples of organisms that are all related to one common ancestor.

One of Wallace’s most notable discoveries is coined the “Wallace Line”. This invisible line abruptly separates animal species that inhabit a string of islands near Indonesia. Typically,

We conclude that there are about 33,000 marine species (mainly animals) in the major databases, of which 130 are introduced, 58 listed as threatened and an unknown percentage endemic. An estimated 17,000 more named species are either known from the Australian EEZ but not in the present databases, or potentially occur there. It is crudely estimated that there may be as many as 250,000 species (known and yet to be discovered) in the Australian EEZ. For 17 higher taxa, there is sufficient detail for subdivision by Large Marine Domains, for comparison with other National and Regional Implementation Committees of the Census of Marine Life. Taxonomic expertise in Australia is unevenly distributed across taxa, and declining. Comments are given briefly on biodiversity management measures in Australia, including but not limited to marine protected

This lack of criteria is what causes the exclusion of taxonomic acknowledgment of major evolutionary innovations while inaccurately portraying history. It is also mentioned in Greene’s more recent journal that the Linnean method fails at specifying clades based upon the origin of limbs in tetrapods and shelled egg amniotes. While it also, “obscures the fact that crocodilians are more closely related to birds than they are to turtles, lizards, and snakes,” which does not highlight many dramatic similarities between earlier archosaurs (Ballen, Cissy J., and Harry W. Greene). These two main concerns of omission and obscuration are why the phylogenetic clade-based system is a far more valuable and beneficial methodology for teaching zoology.

In Chapter 23, we talked about the many different ways that a population can evolve over time. Relating to the topic of this chapter, an academic journal published by Karasawa et al. (2015) discussed how different species of scorpions existed on different islands of Japan and Taiwan. From what we previously know about evolution, these scorpions could have been the same species at an early point in history but due to the founder effect, one species might have established a new population. This could have been a result of the islands being separated by the Kerama Gap, a specific waterway that separates these two species (Karasawa et al. 2015). It is a possibility that these species of scorpions have a common ancestor and because of the changing

Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for

Through the work of curious minds before them, Darwin’s inspiration working as a naturalist on the HMS Beagle and traveling to the Galapagos Islands, and Wallace’s promptings for publication in 1856,

One of real main impetuses considered in the taxon cycle and above all in the Theory of Island Biogeography is the extinction (natural) of species. The extinction created specifically by people colonizing secluded islands of the globe has been emotional. The measured the dissemination of useful differences, a real segment of natural differing qualities, in 45 pre‐historic island fowl groups of the Pacific and archived its decrease by means of species
