Genetic drift and natural selection both play important roles in shaping the genetic makeup of a population in nature. Although this is true‚ they have different modes of doing so. Genetic drift‚ unlike natural selection‚ is a completely random process. While natural selection tends to improve the fitness of generations to come in the context of a certain environment‚ the chance events of genetic drift do not necessarily lead to forming positive environmental adaptions. In addition‚ the effects of

The Holderness coastline is very low lying and runs along the North East coast of the UK from the chalk cliffs of Flamborough Head in the north to the sand spit of Spurn Point in the south‚ a distance of 61 km. The Holderness Coast is famous due to its history of being one of Europe’s fastest eroding coastlines.

Discussion: Referring to the hypothesis we predicted in the beginning of this experiment that under ideal conditions‚ we hypothesized that the results will eventually follow the Hardy-Weinberg expectations‚ which means the genotypes frequencies of the Drosophila melanogaster would remain constant; Therefore‚ no evolution had happened to the flies under the ideal conditions. After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to

It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg‚ 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham
