Zak Murdock Period 1 Video Question 1. The theory of evolution is supported by an ample amount of evidence generally accepted by biologists. Major evidence for the theory of evolution comes from fossils. The fossil record allows biologists to view a snap shot of the past and when assembled, fossils illustrate the evolutionary change that has taken place over the past four billion years. Transitional forms also provide evidence to biologists that support the theory of evolution. Transitional forms are fossils or organisms that show the intermediate states between an ancestral form and that of its descendants. Homologies are similar characteristics due to relatedness and are a major form of evidence for evolution. Homologies can be revealed by comparing the anatomies of different living things, looking at cellular similarities and differences, studying embryological development, and studying vestigial structures within individual organisms. The theory of evolution predicts that related organisms will share similarities that are derived from common ancestors, which in turn proves that homologies are indeed an important form of evidence for biologists to study evolution. Also the distribution in time and space is used as evidence for the theory of evolution. In order for biologists to better
