Charles Darwin's The Origin Of Species

The changes in species have been explored by many scientists, but Charles Darwin was the first to support his findings on the existence of evolution with abundant evidence. Darwin later came to develop the theory of evolution after his voyage on the HMS Beagle to South America in 1831 for five years. Darwin was an English geologist and naturalist who proposed that organisms have had physical and behavioral changes over time to increase reproductive success and to better adapt to the environment. Darwin expanded on two main ideas, which were that all organisms are derived from a common ancestor and that evolution is steered by natural selection. He described natural selection in simpler terms as the survival of the fittest, in which the fittest refers to organisms that can produce the most offspring. In 1859, he expressed these ideas by publishing the novel The Origin of Species and challenged societal views on the organisms on Earth being immutable. Darwin was the primary reason that lead to the understanding and …show more content…
Referring to figure 1, it depicts the relationship that time has with finch population and average beak depth when there is an average rainfall of 25 cm. It justifies the first hypothesis as the finch population remains almost the same over the span of five years and the beak depths of the birds are essentially constant. However, in reference to figure 2 challenges the second hypothesis as the overall trends from the results demonstrate that although the finch population does decrease with drought, their average beak depth increases over time. Likewise, in reference to figure 3 challenges the third hypothesis as the general trends exhibit that the finch population increases, but their beak depths decrease over a five year period. The trends expressed by figure 2 and figure 3 show the progress of the finches adapting to changes in the environment over
