1 I Can Statement Conversation/Assignment 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. I can... identify fields of science that provide evidence for biological evolution; paleontology, anatomy, embryology, and biochemistry summarize the ways that each field of science listed provides evidence for evolutionary relationships compare the evidence within the fields that scientists use to critically analyze evolutionary ancestry In your own words, briefly explain what scientists do within these fields: Paleontology Anatomy Embryology Biochemistry How does Biochemistry help us with our understanding on Embryology? How does Paleontology help us with our understanding on Anatomy?

2 illustrate evidence for biological evolution using pictures, diagrams, or words infer relationships among organisms based on evidence from each field of science listed What field is the below referring to? Which primate is most closely related to humans? Which primate is least closely related to humans? Why is this evidence of evolution? What field is the below referring to? Which of the above species would be most biochemically similar to humans the fish or the pig? Why? How does a comparison of these embryos provide evidence of evolution? What field (left) is this referring to? The similarity of structure is evidence that the animals. Humans, chimpanzees, whales, and bats all have the same bones in their arms, fins, or wings. This type of evidence is Homologous structures. Why is this evidence of evolution?

3 What field (right/below) is this referring to? With the diagram on the right, label the fossil that is the oldest. Label the fossil that is the youngest. The above figure illustrates the phylogeny of elephant skulls. Why is this evidence of evolution? I can... define homologous, analogous, vestigial, and embryology (above) explain how analogous and homologous structures provide evidence for evolutionary relationships In your own words define, provide a connection, or draw picture etc.: Homologous structures Analogous structures Vestigial structures (include example) Match the following with Homologous or Analogous Humans, rabbits, and zebras all have an appendix, an extra piece in their digestive system, although in humans it s much smaller. What type of evidence is this? How does this help provide evidence for evolutionary relationships?

4 Honey possums lick nectar from flowers using a long tongue made of soft muscle. Butterflies lick nectar from flowers using a long tongue made of hard protein. What type of evidence is this? How does this help provide evidence for evolutionary relationships? infer how the fossil record has challenged scientists in paleontology explain how evidence from a variety of scientific fields is continually gathered to create a more accurate picture of evolutionary relationships How does the fossil record challenge scientists? (think about our cartoon activity) Can our understanding of science be altered? How? explain how biochemists use DNA evidence to show evolutionary relationships The human gene for your muscle protein is different from monkey muscle protein in 4 places and different from a chicken s gene in 25 places. What does this tell us about evolutionary relationships between humans and monkeys? Chickens?

5 define phylogeny, convergence and transitional fossils In your own words and the diagram example define, provide a connection, or draw picture etc.: Phylogeny: Example: phylogeny of the elephant showing. Convergence: Example: What trait(s) in the figure to the right shows convergence? Transitional fossils: Example: Archaepteryx is a transitional fossil between and.
