  1. BIO 123 – Biological Science II Course Context: Descent with Modification unit

  2. Learning Activities • Students read text before lecture • Students work in small groups to prepare for mock debate – group works on either Lamarck or Darwin • Student groups ‘debate’ the POV by sharing their example and how that example supports their hypotheses • Lamarck groups: • Define characters • Describe the role of the environment on characters • Explain Lamarck’s hypothesis of use and disuse • Explain Lamarck’s hypothesis of acquired characteristics • Compose an example that supports Lamarck’s hypotheses • Darwin groups: • Define characters • Describe the role of the environment on adaptation • Explain Darwin’s hypothesis of natural selection • Explain Lamarck’s hypothesis of descent with modification • Compose an example that supports Darwin’s hypotheses

  3. Formative Assessments • Students take quiz on the reading on Mastering Biology before lecture •  Mock debate • Students given practice exam questions through weekly quiz • Online quiz, can retake once

  4. Summative Assessments • In-class exam • How would vestigial traits be explained if evolution occurred via inheritance of acquired characters as proposed by Lamarck? • 2.33 A) as the product of natural selection • 62.79 B) as a change in an individual's phenotype in response to an environmental challenge • 27.91 C) as a change in a population's phenotype in response to an environmental challenge • 6.98 D) as the product of instantaneous creation by a supernatural being • According to Darwin, adaptationsare______ characters that enhance survival and reproduction in _________. • 67.44 A) inherited; a specific environment. • 0.00 B) inherited; all environments. • 30.23 C) acquired; a specific environment. • 2.33 D) acquired; all environments. • A dog trained to guide the blind has offspring. None of the offspring can guide the blind. Does this situation support or refute Lamarck’s hypothesis of inheritance of acquired characters? Explain why or why not.

  5. Timeline • Most likely changing jobs within the next few weeks • Once I have a course or workshop to design, I will need to develop new learning goals, activities, and assessments
