B-5.5: Exemplify scientific evidence in the fields of anatomy, embryology, biochemistry, and paleontology that underlies the theory of biological evolution.. B-5.6: Summarize ways that scientists use data from a variety of sources to investigate and critically analyze aspects of evolutionary theory.. Variation in Living Things. SPECIES  - Group of organisms that interbreed. VARIATION - small differences between individuals of a species  . Some neither helpful nor harmful  . Some enable organism to be better suited to its environment.. Evidence for Evolution. What is Evolution??. Change in the genetic composition of a population during successive generations, as a result of natural selection acting on the genetic variation among individuals, and resulting in the development of new species.. Unit 6: Seventh Grade. Theory vs. Law. An idea that has . not. been proven to be unequivocally true. Examples:. Big Bang. The extinction of the dinosaurs. An idea or truth that . has . been proven to be unequivocally true. Organism DNA. 1a. Some of the strongest evidence for evolutionary relationships comes from studying the DNA of different organisms.. 1b. The fact that all organisms use the same DNA molecule to code for genetic information suggests that these organisms share a distant ancestor.. LAMARCK (1744 – 1829) . He proposed . 3 theories. to explain how species change…. Theory of Need. Theory of Use and Disuse. The Theory that Acquired Traits Can Be Passed on to Offspring.. August Weismann (1834-1914). 30 Minute Inquiry Activity. Research one of the following types of Evolutionary Evidence:. Fossil . Record. Vestigial . Structures. Homologous . Structures. Comparative . DNA. Note . the following about your type of evidence:. A mechanism for change in populations.. Any change in the . inherited . traits within a population across generations. Individuals better adapted to their environment tend to survive and . produce more offspring. By Dr. J. Suris Soto. Objectives . By the end of this lesson you should be able to . List several examples of evidence for evolution.. Explain how fossils, and the fossil record document the descend of modern species from ancient ancestors.. Evidence for God part 2 (11-22). The Problem of Evil (11-29). The Bible and Science (12-06). Creation (12-13). Evolution (12-20). The Genesis Flood (12-27). Archeology (01-03). Historical Jesus (01-10). Early scientists proposed ideas about evolution. . Evolution is the biological change process by which descendants come to differ from their ancestors.. A species is a group of organisms that can reproduce and have fertile offspring.. Chapter 17: Processes of Evolution. Early Beliefs. 19. th. century: discovered species shared many traits, but lived in different parts of the world. Problematic – species only looked similar on the outside, but inside were very different . Pd-2 . Anatomy and Physiology. Evidence for evolution can come in the form of anatomy and physiology. For example vestigial, analogous, and homologous structures. . Vestigial Structure:. The concept of vestigiality applies to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species. An example is the human appendix.. . The process by which organism change over time. Based on science, not opinion.. Darwin. :. Evolution is descent with modification. Evolution. :. changes through time. Species accumulate difference.
