The Contributions Of Evolution : Charles Darwin And Natural Selection

Decent Essays

The history of life on earth extends three billion years ago, over time, life accumulated a significant amount of changes since their introduction. One of the most important figures exploring this change, also known as evolution, is Charles Darwin. Darwin was an English naturalist, geologist, and biologist, known for his contributions to the science of evolution. He developed the theory that all organisms in Earth’s surface have descended over time from common ancestors. He also introduced his scientific theory that this branching pattern of evolution resulted in a process that he called natural selection. Natural selection further contributes to the mechanism of evolution due to the fact that it explains the differential survival and reproductive aspects of each species. Furthermore, Darwin established another major concept known as variation. The variation occurs partly because random mutations arise in the genome of an organism, and offspring can inherit such mutations, this a key concept to understand why the organisms in Earth evolve. These mutations, depending on the environment, can be beneficial, detrimental or neutral. Whales are species that always raise questions in the scientific community due to its evolution. In order to understand the evolution of whales necessary to understand the origins of whales, their transition from land to sea and the function of their limbs.
In 1936, Remington Kellogg, a scientist of that time, studied several fossils of whales,
