Since the publishing of Charles Darwin’s Origin of Species, where the theory of evolution has arisen from, people have debated Creationism versus Evolution. Through supporting facts and statements the theory of evolution will be defended as being more than just a theory, and proven as fact. Evolution as a fact is reinforced through; scientific studies on DNA, genetics and its mutilation, the Fossil Record and the change in earlier species that has been found, and finally the distribution of related species of animals over a broad geographical range.
What is a Fossil? “Fossils are the mineralized remnants or impressions of once-living organisms” (www.actionbioscience.org) Which means “the remains of plants and animals from the past that have been encased in rocks”. Now, let’s take Dinosaurs for example. They don’t exist today, however evidence found fossil records of them. This is proof of Dinosaurs once roaming the earth. Fossils are usually found in sedimentary rock. Sedimentary rock is formed by layers of silt or mud on top of each other; thus, the resulting rock contains a series of horizontal layers, or strata. As these Sedimentary rocks form, they bury organism, bones, pollen, shells. Bones, which over time will fully encase, and form a fossil.
Each layer of sedimentary rock contains fossils which are typical for a specific time period during which they were made. This fossilization easily allows us a “window to the past” of how organisms have grown more complex, physically, and biologically, and gives us clear proof of the Evolution Theory. Thus confirming that over time life has grown more complex and changed over time.
Moving on from Fossil Records giving dated proof of the occurrence of Evolution, is the similarities of species over a large geographical reason. Geographic distribution of related species and the...
