Unit: Evolution (written November 2013) Key Learning: By a process known as natural selection, all the different species found on Earth have developed, and continue to change, as time passes Instructional Tools: Unit Essential Question: How do different kinds of organisms develop? How does natural selection drive changes in life? Concept: Darwin and Natural Selection 3.8.10.C, 3.2.10.A, 3.3.10.C, 3.3.10.D BIO.B.3.3.1, BIO.B.3.1.2, BIO.B.3.1.3, Lesson EQ: Concept: Genes, Variation, Natural Selection, and Developing New Species 3.1.10.E, 3.3.10.B, 3.3.10.A, 3.8.10.C BIO.B.3.1.1, BIO.B.3.1.2, BIO.B.3.1.3, BIO.B.3.2.1, BIO.B.3.3.1 Lesson EQ: Concept: Human Evolution BIO.B.3.2.1, BIO.B.3.3.1 Lesson EQ: What led Darwin to develop his theory about how life developed? (A) What is natural variation and what causes it? (A) How did humans evolve from other primates? (A) What were some ideas that helped Darwin develop his theory? (A) How does natural selection affect species? (A) What makes primates different from other groups of mammals? (A) What evidence supports that life has, and continues to go through, processes of change? (A) What is the evidence that shows Homo sapiens evolved? (A) How do species adapt to environmental stimuli? (ET) How does the fossil record support the theory of evolution?(A) How do similarities in physical structures and DNA support the theory of evolution?
