  1. Michigan High School Science Meap Test STUDY of LIFE Biology Review

  2. LE. Biology EvolutionBenchmark 1 Describe what biologists consider to be evidence for human evolutionary relationships to selected animal groups.

  3. Key Concepts Common types of evidence used hominid fossils vestigial structures DNA protein structure

  4. Real-world contexts Skeletal comparisons, such as: modern human to hominid fossils; Anatomical/biochemical similarities humans to other higher primates, such as: blood proteins Similarity of early human embryo stages to those of other vertebrates Vestigial structures, such as: appendix tail bone

  5. The human embryo and the embryos of other animals • with backbones have gill slits. According to modern • evolutionary theory, this best supports the ideas that • fish are our closest relatives • all embryos breathe through gills • C. all animals with backbones are related by common ancestry • D. all organisms have gill slits at an early stage in their development Go on to question two

  6. A. fish are our closest relatives Incorrect: the question says animals with backbones. This would include many animals, not just fish. Our closest relatives are other primates, such as chimpanzees. Return to this question

  7. B. all embryos breathe through gills Incorrect: at an embryo stage humans get their oxygen from the mother via the placenta and umbilical cord. Return to this question

  8. You Pass with Flying Colors C. all animals with backbones are related by common ancestry Correct: organisms who share embryonic traits also share a common ancestor. Common ancestry is one of the key ideas in evolutionary theory. Return to this question Go on to question two

  9. D. all organisms have gill slits at an early stage in their development Incorrect: the question says animals with backbones, not all organisms. (all organisms would include bacteria, fungi, plants…) Return to this question

  10. Look at the data table above. It shows the number of differences • in the amino acids that make up the hemoglobin molecule found in • several species when compared with human hemoglobin. • Using the data table above which species • is most closely related to humans? • A. Frog • B. Pig • C. Gorilla • D. Horse Return to Question One

  11. Try Again Return to this question

  12. Try Again Return to this question

  13. You Pass with Flying Colors The correct answer is C gorilla. The more closely related two organisms are, the less differences they will have in their DNA and therefore their proteins. Since Gorillas have only one difference and the frog, pig, and horse have more than that, the human and gorilla are the closest. Return to this question Return to Question One

  14. Try Again Return to this question
