Chapter 19 | Evolution and the Origin of Species
- If a person scatters a handful of garden pea plant seeds in one area, how would natural selection work in this situation?
- Why do scientists consider vestigial structures evidence for evolution?
- How does the scientific meaning of “theory” differ from the common vernacular meaning?
- Explain why the statement that a monkey is more evolved than a mouse is incorrect.
- Why do island chains provide ideal conditions for adaptive radiation to occur?
- Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which the females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy that it was hard for females to distinguish colors. What might take place in this situation?
- Why can polyploidy individuals lead to speciation fairly quickly?
- What do both rate of speciation models have in common?
- Describe a situation where hybrid reproduction would cause two species to fuse into one.
- Solve for the genetic structure of a population with 12 homozygous recessive individuals (yy), 8 homozygous dominant individuals (YY), and 4 heterozygous individuals (Yy).
- Explain the Hardy-Weinberg principle of equilibrium theory.
