To start, evolution is, from the lecture Evolutionary Biology: All things great from small, the transformation of animals, plants, and other living organisms into different forms by the accumulation of changes over successive generations (OED). Based on Darwin’s argument, it has been taught that natural selection is known for the causes of evolution because natural selection is the process of which the environment favor the species with favorable traits that will help them survive. Scientists…

Genetic Engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. With this new, rapidly growing, technology we are now able to do things that we once thought were impossible. In Ethics and the New Genetics, the Dalai Lama addresses problems that we need to consider as we continue to explore this microscopic world that we have…

Forces of Evolution Mammals have evolved in ways that are beneficial for them, ensuring their survival and turning them into the beings that we are familiar with today. Species, organisms which have always had features in common, evolve through four main forces: gene flow, genetic drift, mutations, and natural selection. Genetic drift involves a population, a group of the same species that lives in the same geographical and temporal location. Genetic drift causes changes to occur in members…

genes, the means to replicate this DNA, and all the molecular tools needed to construct protein molecules from their DNA-encoded blueprints” (De Duve: 1996, p. 51), and it is highly dependent on mutations to occur “for essentially asexual, haploid organisms such as prokaryotes, mutations are a major source of genetic diversity and one of the essential factors in the formation of novel species” (Whitman et al: 1998. p.6589). The way that the animal cell and prokaryotic cell compare towards the…

energy in an ecosystem with the organisms of a community. There is an energy pyramid to show how the percentage of producers or consumers. Energy pyramids can be made by using a food web. The bottom layer is where there are primary producers, which has 100%. There are ten percent of primary consumers, one percent of secondary consumers, and a tenth are third level consumers. Energy pyramids shows how energy flows in a community. The different levels have different organisms. There is an…

In Neil Shubins’ “Your Inner Fish: A Journey Into the 3.5-Billion-Year History of the Human Body”, he takes the audience on the journey of the discovery and history of how different organisms and adaptations have converged to form a relationship between fish and tetrapods. Shubins first relates the evolutionary fact that humans and other forms of “tetrapods’ major body systems have developed from fish and sharks” (20), through his time on the field as a paleontologist. He describes his multiple…

Ancient Greek debated whether living organisms were composed of endlessly divisible fluid or indivisible subunits. However, this debate was settled and closed with the invention of the microscope which is the required material to understand and observe cells. Let us begin with the ABC’s of the Cell Theory which splits into 3 major parts: All living beings are made up of cells Cells are the basic unit of structure in all organisms All cells come from preexisting cells. To have a deeper…

The four forces of evolution include mutation, gene flow, genetic drift, and natural selection. Mutation occurs when the base pairs in DNA change which leads to different codons being read during translation. Most mutations create codons for the same amino acid that the normal codon would have made but sometimes a different amino acid is made and that leads to changes in the organism's phenotype. Gene flow happens when two different populations come together and reproduce with each other. The…

Catholic College biology class, took on the role of a field officer for the Department of Environment and Climate Change to investigate the biological community present near Euroley Bridge, Yanco. During their time, they were to observe the various organisms that are found in the ecosystem, taking into account their surroundings amid this process. They were provided with a booklet that had various activities which were intrinsic to their Field reports such as a site plan and a profile-transect.…

also an equal amount of risk. Genetic engineering is the process of manually adding DNA to an organism. This can be any organism like, animals, plant and humans. Some scientist refer to this as cell manipulation. Genetic engineering is most usually used for plants. No one really uses it for humans, because its dangerous. The process for genetic engineering involves a gene or trait injected into an organism. For example a mother can genetically engineer her baby to have a certain color of eyes,…
