Charles Darwin s Theory Of Biblical Creation - 1028 Words

In 1831 Charles Darwin graduated from Cambridge, with a Bachelor of Arts Degree, yet Darwin was far more interested in geology and biology. Taking a drastic turn in his studies, Darwin became fascinated in the scientific findings of geologist Adam Sedgwick and the naturalist John Henslow. Prior to the expedition, Darwin, along with his mentors rejected biological evolution. Darwin s mentor, Henslow, was able to secure a spot for Darwin on the H.M.S Beagle. This expedition was a 5 year journey, which eighteen months consisted at sea. Two days after Christmas, at the age of twenty-two, Darwin set out on the journey as an unpaid naturalist and companion for the captain, Robert Fitzroy. During this expedition was a five week visit to the†¦show more content†¦The variations in the beaks gave the finches the benefit to stay alive long enough to reproduce these traits and pass them on a generation. As these traits were passed down from generations to generation, this is how the fin ches, which were assumed to be one species evolved into the findings of thirteen different species. Moreover, Darwin called this â€Å"descent with modification.† The finches are the prefect example of this approached worked. The birds with beaks shaped that were better suited to get nectar from flowers or eating hard seeds; just as beaks which were suited for eating cactus had an advantage in the environments. Natural selections meaning can be simplified as to which traits have the advantage to survive and reproduce in the environment they are living in. This meaning should not be confused with believing that the environment itself creating different species, yet the most suitable species will survive against the ones with less useful traits. The four processes of mechanism of evolutionary change are mutation, migration, genetic drift, and natural selection. A mutation is permanent damage to either the DNA or the RNA genomes, possibly resulting from chemicals, radiation, errors, or deletion/insertion to a segment of the DNA. There may be or not be any useful effects that mutations have on a species, however, mutations that reoccur most
