Essay on Evolution Lab - 751 Words

1. Did the construction of the phylogenetic tree based on the 14 living Caminalcules change the way you would group Caminalcules species in your taxonomic classification (chart)? What does this suggest about classification based on strictly of similarity versus evolutionary relationship? The phylogenetic tree was more of an evolutionary tree. It showed the evolution of the organisms and their ancestors or traits that they branched off of. The chart however just simply organizes and separates the organisms in similarity. The tree did not change the chart, the chart see similarities with structures between the modern day organisms and the tree shows their evolutionary linage. The tree reflected our taxonomic classification. 2. Did your†¦show more content†¦A good example of this would be â€Å"living fossils† like the horseshoe crab or cockroach. Provide an example from your phylogenic tree of evolutionary stasis. Discuss the ecological conditions that might result in this sort of long-term evolutionary stasis. An example of evolutionary stability would be species 13, the species survived more than 13 million years and now is a â€Å"living fossil†. The ability for the species to reproduce and survive in an area means a there is no need for the species to evolve. Unchanging ecological conditions results in this long term stasis. 6. Some Caminalcules went extinct without leaving descendents. In the real world, what characteristic of a species (not of their enivornment) might increase the probability of a species going extinct? The ecological conditions might have changed quickly and the species was not able to adapt to those conditions, which eventually lead the species to go extinct. 7. Find two examples of convergent evolution among the Caminalcules. This means finding cases where two or more species have a similar characteristic that evolved independently in each lineage. The wings of bats, birds and bees is an example of convergence since the three groups did not inherit the characteristic from their common ancestor. Write your answers in complete sentences (e.g. â€Å"Species x and y both have ____ but their most recent common ancestor, z, did not†). The claws of species 3 and 12 (their most recent common ancestor,Show MoreRelatedEvolution Lab Essay594 Words   |  3 Pagesdocument to report your findings from the EvolutionLab Exploration Experiment.

This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied.

By entering this protein into the Entrez Protein Database in the National Center for Biotechnology Information, and using tools within this database such as Jpred, SMART, and Protoparm, the given protein could be fully analyzed. This experiment was very successful as our particular protein could be identified, and the tools within the NCBI database allowed us to fullyRead MoreEvolution Lab: The Impact of Drought Conditions on a Finchs Beak Size856 Words   |  3 Pagesrelative percentage of the three levels of hardness changes across a rough continuum. Seed hardness would be predicted to increase finch beak size because more force would be needed to crack open the seeds. This would be an example of directed evolution, because drought conditions will favor one extreme of the finch population, those with larger beak sizes. The bell curve would thus shift in favor of larger beaks. Hypothesis: Drought conditions on Darwin Island will increase the prevalence ofRead MoreEvolution And Natural Selection : The Benefits Of Mutation1321 Words   |  6 PagesEvolution and Natural Selection; The benefits of Mutation Areeba Yousuf Introduction Charles Darwin, a naturalist around the 1800’s , discovered the theory of evolution. He discovered this observation of evolution with his voyages around the world. The specific animals that proved Darwin s theory were the finches he discovered in South America, and then found many variations at many different places. He studies these finches in depth and discovered that they were similar yet somehow different;Read MoreDarwin s Theory Of Biological Evolution1347 Words   |  6 Pagesâ€Å"Evolution refers to the processes that have transformed life on Earth from its earliest forms to the vast diversity that characterizes it today† (Campbell, 1993). However, a lot of things can change over a period of time. The â€Å"Father of Evolution† who is known as Charles Darwin, developed the theory of biological evolution. This theory has long been debated during and after darwin s time. Biological evolution can be seen through a momentous change in organisms by chang ing of the genetic compositionRead MoreIntelligent Design: An Intelligent Way of Disguising Religion1346 Words   |  6 Pagesand Eve have been apes? Evolutionists say humans evolved from apes, but many religious people cannot swallow the thought. For years, religious people have voiced their unhappiness that schools teach evolution. The Bible says that God put all the plants, animals, and people on this planet, and evolution completely contradicts that. The idea of including creationism in schools has been brought to courts multiple times but with no success. Now the creationists have a new way of presenting it. They disguiseRead MoreSex-Linked Traits Through Meiosis and How It Relates to Genetics.1609 Words   |  7 Pagesexamining the hierarchy that ranges from the fundamentals of cell biology to the physiology of organisms, and the interactions among those organisms in their environment.

We use bean-bag model to simulate allele and genotype frequencies for three generations of deer mice under three different selective regimes. Then, we use the Hardy-Weinberg Principle to assess the selection and evolution experienced by deer mice. The Hardy-Weinberg Principle is one of the most
