Why Did Evolution Happen
There is a great deal of evidence to support that evolution did indeed happen. Evolution is the changes in a population over time, it’s explained through descent with modification and natural selection. The findings from earlier thinkers all back this evidence up.
Charles Darwin used evidence he found from research and studying the work of other scientists who studied fossils to support his claim that modern organisms are the descendants of ancestral species that were different from those of today. Darwin based his ideas on the work of Nicolas Steno ,a 1600’s anatomist working in Italy. He dated rock by saying the oldest layers were the deepest layers (“Understanding Evolution: Nicholas Steno”) He thought that Fossils were snapshots of life at different moments in earth’s history. Steno was struck by how similar shark teeth …show more content…
resembled “tongue stones”, Steno thought Fossils fell from the sky.
He then discovered that the “tongue stones” did indeed come from the mouths of previous living sharks. When Steno looked at a elephant fossil he saw that it wasn't the same species of living elephants. It was much different Georges Cuvier a French naturalist and zoologist in the 1700’s joined the fledgling Nation Museum in Paris in 1795 and became the world’s leading expert on the anatomy of Animals, He found that some animals just vanish, He called this extinction. He was referred to as the father of “paleontology” He found after looking at fossils that a mass extinction is very possible Georges Cuvier was a main contributor to Extinction. While Darwin was in South Africa he saw that many of the fossils there proved to be extinct relatives of some of the life in modern Southern American Organisms (Weiner 29) . Darwin then said these fossils were relatives but they were not the exact same because of some differences of the organisms. He figured the elephants were
closely related but not 100 percent the same Cuvier helped Darwin realize and learn about the fossil records and some of our ancestors that we may not even know about. Fossils were the biggest evidence for Darwin that evolution and extinction has changed these life forms.
Darwin used work and research from earlier scientist Carolus Linnaeus, who put organisms into groups called species based on their differences and similarities. Linnaeus studied comparative anatomy to support his claim that modern organisms are the descendants of ancestral species that were different from those of today. He gained a lot of his knowledge from Linnaeus from his classification system. Darwin used these species to say that we have a common ancestor and the research from Vesalius from his dissection of the human body. We performed a Homologies lab in glass which we studied and compared the bones of a Dog and chicken wings and an Iguana leg to get a better understanding of these similar bone structure. We found that in the arm bone forelimbs of humans, iguanas, chickens and dogs have the same bones in their arms. This similarity indeed suggests that we all have a common ancestor that we are all descendants from.
