For example, the third chapter deals with Henry Walter Bates’s discovery of how harmless species have evolved to appear like a venomous neighbor species to avoid predation. The first and last stories, though, are the ones that include the two other biological concepts.
The first story describes Darwin’s voyage on the Beagle and how he …show more content…
As can be expected, both natural selection and mutation are explained in this section of the Framework. The importance of knowing evolution, simply put, is that it “explains the diversity and unity of life” (AP Biology Curriculum Framework, n.d., p. 4). By knowing evolution, one can understand why and how all life has become what it is today. To comprehend the “driving force” behind evolution, one must be familiar with natural selection, which allows individuals with conducive traits to pass their traits onto the next generation. Finally, to cognize how different traits form, one must know of mutations and how they “can be positive, negative, or neutral” (AP Biology Curriculum Framework, n.d., p.51), thus allowing natural selection to eliminate deleterious phenotypes caused by negative changes to the genotype. Learning objectives 1.1-1.26 apply to the concept of evolution; LOs 1.1-1.5 and 3.24 apply to natural selection; LOs 3.24-3.28 apply to
