Manasi Gaje BI 309: organic evolution Paper 1 Human phylogeny as a Tinkerer When the word chub mackerel is presented row much(prenominal)(prenominal) as innovation, creativity, and experimentation almost always come to mind. What is mirthful amazing is to compare a vast concept such as evolution to that of a tinkerer. Such is the case with FranÃ§ois Jacobs 1977 paper Evolution and Tinkering. In his paper Jacob argues that evolution is non same(p) an engineer who has an exact plan, complete with blue prints and every(prenominal) the correct last required for a perfect creation, entirely rather evolution is a tinkerer who plays with different parts and works with what he is given. The tinkerer unlike the engineer has no final terminus to reach, but rather tweaks certain characteristics or parts to salvo into the bigger picture. While the engineer has unrivalled fool-proof solution to all given difficulty the tinkerer comes up with many different ways to solve one problem this rear end be seen in the variety of the models of eyes in the many species on earth and how each evolved. Lastly the tinkerer does not perform from nothing; he always builds on top of what already exists. This is true of evolution which gives new functions to already existing characteristics (Jacob). Examples of this tinkering can be seen in the human being sapiens or sympathetics.
It is said that the evolution of the unexampled human being has interpreted speckle over 6 million old age. Because at that place is fossil evidence that shows physical similarities that links a public ancestor to many order Pri mates, humans are considered primates. Whe! n flavour for tinkering in human evolution, characteristics that stand out are, bipedalism, encephalization, and the various vestigiality in the human body. Figure 1: Phylogenetic tree of the modern Homo sapiens originating from around 6 million years past from the Sahelanthnopus tohadensis. One trait that really sets the humans away from some other primates is the ability to walk upright. This phenomenon is called bipedalism. though many primates today...If you want to get a honest essay, order it on our website: BestEssayCheap.com
