8+Evidence+of+Evolution

Scientists have found mulitple types of evidence to support Evolution. Scientists have found four main types of evidence, these include Fossils, Geography, Embryology, and Anatomy. Along with these and other types, scientists have proved the theory of evolution. **Evolution: The process of biological change by which descendants come to differ from their ancestors. ** Fossils: Late 1700's found certain types of fossils in some layers and not others. Found fossils in the bottom are older and more primitive than those in newer ones. The earliest reported fossil discoveries date from 3.5 billion years ago, however it wasn't until approximately 600 million years ago that complex multi-cellular life began to enter the fossil record, and for the purposes of fossil hunting the majority of effort is directed towards fossils of this age and younger. A pyritised //Echioceras// ammonite from [|Charmouth] Embryology:Is a science which is about the development of an Embryo from the fertilization of the ovum to the fetus stage. Anatomy:  This is a picure of the whale ancestors. Over time mammals turned into sea creatures. When it comes to evolvability, time is the least important factor to consider. The rate of evolution is determined primarily by population size, reproduction rates, and mutation rates. The larger the population, the smaller the generation times, and the faster the mutation rates, the faster the rate of evolution. The smaller the population, the larger the generation times, and the slower the mutation rates, the slower the rate of evolution. If you have a small population, long generation times, and an average mutation rate, it will take a long time for mutations to create enough raw materials on which natural selection can act. To see how this works, contrast whales and mice. Because of the small population size and long generation times of whales, it takes whales 200 million years to accumulate the same number of mutations mice can accumulate in 1500 years. If mice haven’t changed in 1500 years, then why should we expect mammals to have evolved into whales over a period of 200 million years, yet alone the 10 million years in which it is claimed the process took place in? Geography: The Landsat series of satellites enables us to see change in the land surface over time. The Mississippi River deposits sediments from the central United States into the Gulf of Mexico and thereby builds the Mississippi Birdfoot Delta in Louisiana. Upon reaching the Gulf, the river's velocity slows, reducing the river’s capacity to carry suspended mud and sand. This sediment is deposited in a fan pattern. Clearly, significant change has occurred in just three decades.
