Evolution is defined as the process by which defferent kinds of living organisms are thought to have developed and diversified from
earlier forms during the history of earth. Without a scientific perspective on life, evolution is just a misterious thought. The begening of
biological inquierey began more than 2000 years ago with the Greek philosoper, Aristotle. Aristotle was a naturalist and used science to form
the idea of evolution. He (and all naturalists) used biogeography to begin investigating and researching spieces and their changes since the
begening of life.
Fossils are a key piece of observing evolution. Naturalists, such as Aristotle, discovered that there were useless parts and bones in
some spieces with studying fossils. Back then, previous beliefs were that every speice was created perfectly. However, discovering the
morphology of bones and fossils and the fact that those speices that had useless bones were becoming extenct only assisted in the theories of
evolution and the changes that were thought to be taking place.
The theory of evolution evolves from more than just the concept of useless bones and such. There are multiple ideas of naturalists
that devolop and suport the theory. Charles Darwin was another naturalist who took pride in scientific discoveris and supporting the theory of
uniformity was another link to the puzzle. The idea that gradual, repetitiive change had shaped the Eath is the "theory of uniformity" proposed by
1831 arthor, Lyells' book, "Principles of Geology." Lyell explained in his literature how change in Earth's surface was more likely from everyday,
gradual geological processes such as errosion over large amounts of time, that time being more than the 6,000 years of age (then being the
allaged age of our planet).The arthors ideas enlightened Darwin into geology and the history of his locations during his travels to South
America. During Darwins voyage, he retained many samples and specimans that he sent back to England to have studied. WIth his studies and
notes, he then developed the process of natural selection, a process of which enviremental struggles would cause only those with inhearited
traints from reprodution and bloodlines to survive. This only made evolution seem more likely and factual.
Radiometric dating helped with evidence of evolution as well. This is a method of estimating the age of a rock or fossil by measuring
the content and proportions of a radioisotope and its daughter elements. An example of radiometric dating backing up evolution is the discovery
of intermediate forms of whales, dolphins and propoises. Evolutionist scientists always thought that the ancestors of such animals walked on
land and then adjusted to life in water. THeir evidence for such theories were the shape of their skulls and lower jaws being the same as
ancient land animals. They also shared DNA likeness with some animals that were hooved mamals with even numnber of toes....
