Article # 1: universal resource locator: http://www.nature.com/nature/journal/v457/n7231/full/nature07891.html MLA Citation: Shubin N, Tabin C, & group A; Carroll S Deep homology and the origins of evolutionary novelty: a reexamination article Nature International Weekly Journal of comprehension (2009). Number of times Cited: 150 Abstract: * Background: ?As a result, the problems of novelty and homology mother been deeply intertwined for the past vitamin C and a half. It is here, at the interface between these two extensive concepts of evolutionary biology, where fresh data from developmental biology have had an singular impact.  * Summary: This article summarizes deep homology too implies a historical continuity, save in this case the continuity may not be so evident in finical morphologies; it lies in the complex regulatory circuitry inherited from a harsh ancestor.

The staining of deep homologies offers more than new glimpses of evolutionary history, however. such(prenominal) homologies extend a pro put insight into the evolutionary process. * Conclusions:? Homology, as classically defined, refers to a historical continuity in which morphological features in related species are similar in patter n or form because they rised from a correspo! nding grammatical construction in a common ancestor. Deep homology, however, can also be found in contexts in which structures are not homologous in the classical sense. Studies of deep homology are cover that new structures submit not arise from scratch, genetically speaking, but can evolve by deploying regulatory circuits that were first establish in primal animals. But herein lies a scrap for the next generation...If you require to get a full essay, sanctify it on our website: BestEssayCheap.com
