  • The Definition Of Life Farnsworth Analysis

    How does one decipher between living and non-living? In the article, The Definition of life, Professor Farnsworth argues that life is essentially indefinable. He refers to biological life as a continuum. Throughout the duration of the article, Farnsworth explains how in biology, life cannot be dwindled down to yes or no answers. Rather, he quotes, "nature can trick us with questions that have hidden false assumptions" implying that what one defines as "death" is purely subjective. Farnsworth…

  • Essay On Should Evolution Be Taught In Schools

    Creationism, Intelligent Design, and Evolution, three words that seem to be thrown around a good bit, but which of them is “right”? Well, if you define “right” as being the most factual, then Evolution is, by far, the most :right” of these ideas. There is a mountain of evidence for Evolutionary Theory, such as genetic similarities between different species, following change over time in the fossil record, and even seeing Evolution in action. It is because of this evidence that many individuals…

  • What Are Evolutionary Forces Affecting Genetic Variation?

    (Martin et al., 2016). By using multiple linear regression approach, they have found out that selection reduces diversity at linked neutral sites (Martin et al., 2016). Another study has been conducted to investigate natural selection driving the evolution of reproductive isolation in an Australian wildflower, Senecio lautus. Their results suggested that natural selection can create strong reproductive barriers that differentiate populations with potential to interbreed (Richards et al.,…

  • Saquatic Ape Hypothesis

    23. The book “Survival of the Sickest” supports the quotation by Theodosius Dobzhansky stating that, “Nothing in biology makes sense except in the light of evolution.” The book explains the reasoning behind many wonderful events that are related to the human race and their interactions with other organisms through the idea of evolution. Dr. Moalem answers any question appropriate to the actions and behaviors of multiple species under the same goal- to survive and…

  • The Homo Floresiensis

    their evolution. When looking at fossils, they try to see how much variation is needed to name it a new species or not. There are different fossils that are currently being argued about, where it is questioned if the fossil should be classified as a different species or a new one. One of those fossils that is currently being debated on is the Homo Floresiensis, known as “The Hobbit” to paleoanthropologists. It is argued whether Homo Floresiensis is a species, or if is a ruminant of evolution.…

  • Taster Genotype Lab Report

    Results: TAS2R38 Gene he TAS2R38 gene, encodes a protein that allows people to taste the bitter chemical PTC. To begin the experiment, each student tasted two separate pieces of paper to show their individual phenotypes. The first paper was a control, and the second paper was PTC paper. If the individual tasted a bitterness while tasting the PTC paper, they were classified as a taster, and if nothing was tasted they were classified as a non-taster (Leicht 165). Once these expected phenotypes…

  • The Importance Of Global Microbial Diversity

    For a long term, the prevailing logic in global microbial diversity has been “everything is everywhere, but nature selects”, coming from Baas Becking’s 1934 publication, “Geobiologie of inleiding tot de milieukunde” (Baas Becking, 1934). This conclusion was based on the presumption that physical, chemical, and geographical barriers play no role in the global dispersal of microbes, which aerosolise for easy distribution. In this scenario, it would be expected that any given species of microbe…

  • Imperialism And Social Darwinism

    lobbyers for Laissez-faire economics. They felt that to give Britain the means evolve into an industrial society, businesses needed to be able to operate with little government interference. Spencer was influential in applying Darwin’s ideas to social evolution, relating his theories about competition amongst species to social life, justifying his coined term, “survival of the fittest”. The growing gap between the rich and the poor in Britain was not only justified by social Darwinism and the…

  • Importance Of Locomotion In Animalia

    Locomotion is the movement of a body from one place to another. There are various ways in which species of organisms in the 9 major phylum classes of the kingdom Animalia adapted unique muscle systems and how they use them. A phylum class includes organisms that are different but share important characteristics that resulted from evolutionary relationships among major groups of animals that allowed organisms to adapt in terms of the way they locomote. The Phylum Porifera is made up of sea…

  • Genetic Factors In Aggressive Behaviour Essay

    If a positive correlation is found between aggressive behaviour in adopted children and aggressive behaviour in their biological parents, a genetic effect is implied. However, if a positive correlation is found between the adoptee’s aggressive behaviour and the rearing family, then an environmental effect is implied. Although, research by Hutchings and Medinick suggests that environmental factors do not play a role in aggressive behaviour, as they found when looking at 14,000 adoptions in…
