Evolutionary trees convey a lot of information about a group’s evolutionary history. Biologists are taking advantage of this by using a system of phylogenetic classification. In contrast to the traditional Linnaean system of classification‚ phylogenetic classification names only clades. For example‚ a strictly Linnaean system of classification might place the birds and non-Avian dinosaurs into two separate groups. However‚ the phylogeny of these organisms reveals that the bird lineage actually

1. One patient has a grade I tumor of the lung‚ while another patient has a grade IV tumor of the lung. Explain how tumors in various stages are similar and how they differ. (1 point) Both stage I and stage IV lung cancer is presented with cellular differentiation‚ loss of normal tissue structure‚ as well as irregular size and shape of the nucleus. Normal cells are able to divide and die cancer cells are pile up on top of each other forming a tumor. The staging and grading of cancer depends on

Human Cloning: Genetic Advancement or Genetic Manipulation? Some people might argue that the real offense would be to hinder the progress of science and experimental investigation with regard to human cloning. That to do so would mean to deny the right to scientifically explore and gain from such. Exploration and discovery in advanced technologies and science quite often proves to be beneficial to mankind; however‚ even though human cloning capabilities may tempt man’s inherently diabolical God-playing

that the Thylacoleonids were derived from the lineage that contains Wombats and Koalas‚ the Vombatiform line. Diprotodon At 3.8 metres long and 1.7 metres tall at the shoulder‚ the Diprotodon was the largest Australian marsupial known. The sub family Diprotodontinae which included the Diprotodon Optatum‚ lived between 5.3 million years ago to 11‚700 years ago. The Diprotodon may have evolved from the Plicene Diprotodontine Euryzygma throughout the late Pliocene. Much like its closest living relatives
