Argumentative Essay On Evolution Is Real
Evolution Is Real What is evolution? Evolution is the slow change of organisms diversifying their species. This idea was created in 1859 by the book Origin of Species. Darwin, the author, is backed up by several other scientists in their findings. Believe it or not, people thought Earth was a few thousand years old during the early 1800s and before. Although, we know know that is a lie. This changed the whole spectrum of thinking in the aspect of variations in species. This allowed Darwin’s theory to be plausible. Now, scientists have proven for certainty that evolution is an undisputable fact by the observations in modern sciences from molecular biology, direct observations (biogeography), fossil record, embryology, and comparative anatomy.
We are surrounded by life all around us. Whether it be plants, bacteria or animals, we are all related. We look nothing alike sometimes, but we share a common ancestor. One of the defined …show more content…
There are three different types of comparative anatomy: homologous, vestigial, and analogous structures. Analogous do not support evolution because it only looks for function not relation. On the other hand, homologous and vestigial structures do support evolution. Homologous structures are structures that look similar by design. For instance, a human hand is related to a chimpanzee’s arm. The structure includes include one big humerus at the top leading down to two smaller bones, radius and ulna. Eventually, both structures lead to a cluster of bones that separates into a branch of phalanges. This proves we are related. While, vestigial structures are structures that are useless to the modern species but were useful to their ancestors. An example is a whale. Whales have back legs they do not use. This proves they were used at one point for land travel but slowly became useless as they evolved. This is a demonstration to the relation between the whale and
