EQ What evidence convinced Darwin that species could change over time TEK 7ACDE Supported by 5 branches of science Evidence of Evolution The Fossil Record Paleontology Geographic Distribution of Living Things Geography. 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.. IMSS . BIOLOGY . . ~. . . SUMMER . 2011. LEARNING TARGETS. To understand that biological evolution . involves . descent with modification. . To explain and give different types of evidence for the key concept of biological evolution: all life shares a common ancestor.. Evidence of Evolution. Essential Questions. What is the anatomical evidence of evolution?. How are fossils used as evidence of evolution?. What evolutionary evidence do we have from the field comparative embryology?. 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.. 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:. 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.. 2. Fossils provide evidence of organisms that lived in the past. 3. The wing of a bat has bones that are similar to those in the human arm. 4. DNA can tell us how closely related 2 organisms are.. 5. Whales are descended from land dwelling mammals. SBI3U1.

F – Fossil . evidence (remains of ancient organisms). 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.. 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.
