'History of Life Through Time Essay\r'

'1. The website <http://tolweb. org/Life_on_Earth/1> shows the base phylogeny of the three main lineages of life forms. They argon â€Å"Archaea,” â€Å"Eubacteria,” and â€Å"Eukaryotes. ” It also shows â€Å"Viruses” outside of the manoeuvre, with a question discipline indicating that its place in the tree is undetermined, if it belongs in the tree at all. 2. This site attempts to show the two resource phylogenies of the major lineages of life forms. The â€Å"archaea tree” distinguishes two variations of archaea, and shows that archaea be more closely related to eukaryotes than to eubacteria.\r\nIn the â€Å"eocyte tree,” archaea be not specified at all, but eukaryotes atomic number 18 shown as most closely related to crenarchaeota-eocytes, which was a derivation of archaea in the previous tree. 3. Viruses ar not listed in these two phylogenies because they ar not turn out to be actual life forms. Where archaea, eubacteria and eukaryotes are classified as â€Å"life forms” due to their major power to transfer genes, viruses have not been determined to be living. They are therefore not included on these two phylogenetic trees.\r\nAt the other website, <http://www. ucmp. berkeley. edu/alllife/eukaryotasy. hypertext markup language>, a detailed phylogeny of the Eukaryotes is provided. From this it is evident that fungus kingdom are more closely related to kingdom Animalia than to Plantae. 5. Both sites show that the major life classifications are â€Å"Bacteria,” â€Å"Eukaryotes,” and â€Å"Archaea. ” The â€Å"Tree of Life” site shows the alternatives to how closely the lineages are related, giving two examples of how the three field of battles may be nested within each other instead of beingness derived equally.\r\nThe University of California site breaks down the systematics of each domain separately and more specifically, leaving the three domains as sep arate entities entirely.\r\nWorks Cited\r\nHistory of Life with Time. 2009.
