1. Natural Selection is responsible for the genetic changes thatoccur in the population that we refer to as adaptive evolution. Isall genetic change adaptive or can genetic changes that occurwithin population that are not necessarily adaptive?
2. How does sexual selection contribute to adaptive evolution? Whatis the benefit to the individual with traits such as a huge set ofantlers, or an elaborate set of tail feathers?
3. What was Darwin’s dilemma? Contrast micro- andmacro-evolutionary changes in light of Darwin’s proposed mechanismfor evolution. Compare speciation with the evolution of novelforms.
