EvolutionEcology - Essay ExamplePaper starts with the hypothesis demonstrating mitochondrial DNA as primary son of a bitch for investigation of evolutionary diversion among closely related species and development of new approach in terms of PCR-RFLP based rapid and inexpensive techniques to established phylogenitic correlativity among different species. They also investigated correlation between two different approaches and indicated that data obtained by two different techniques may not be identical and thusly caution must be taken to interpret them. For validation of hypothesis the authors selected four avian sp. found in North America, those having high rate of crossroad videlicet, Dendroica occidentalis, D. townsendi, D. virens, and D.nigrescens. To investigate above mention hypothesis the first experiment was based on classical RFLP based technique. The total mitochondrial DNA were Isolated and digested with 14 restriction enzymes to obtained band pattern which was subsequen tly analyzed by David L. Swoffords paup* 4.0d64 program for calculation of Nei-Li distances. Similarly, for sequences based analysis, three genes located on two sites on mtDNA were selected and sequenced, namely 681bp cytochrome oxidase I, and 1074bp ATP synthase8 and 6 genes from 30 representative warbler individuals.
