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.

Critical Thinking Questions
14 . Ecologists often collaborate with other researchers interested in ecological questions. Describe the levels of ecology that would be easier for collaboration because of the similarities of questions asked. What levels of ecology might be more difficult for collaboration?
15 . The population is an important unit in ecology as well as other biological sciences. How is a population defined, and what are the strengths and weaknesses of this definition? Are there some species that at certain times or places are not in populations?
16 . Compare and contrast ocean upwelling and spring and fall turnovers.
17 . Many endemic species are found in areas that are geographically isolated. Suggest a plausible scientific explanation for why this is so.
18 . The extremely low precipitation of subtropical desert biomes might lead one to expect fire to be a major disturbance factor; however, fire is more common in the temperate grassland biome than in the subtropical desert biome. Why is this?
19 . In what ways are the subtropical desert and the arctic tundra similar?
20 . Scientists have discovered the bodies of humans and other living things buried in bogs for hundreds of years, but not yet decomposed. Suggest a possible biological explanation for why such bodies are so well-preserved.
21 . Describe the conditions and challenges facing organisms living in the intertidal zone.
22 . Compare and contrast how natural- and human-induced processes have influenced global climate change.
23 . Predict possible consequences if carbon emissions from fossil fuels continue to rise.

112 Critical Thinking Questions
19. Describe the process that results in the formation of a tetrad.
20. Explain how the random alignment of homologous chromosomes during metaphase I contributes to the variation in gametes produced by meiosis.
21. What is the function of the fused kinetochore found on sister chromatids in prometaphase I?
22. In a comparison of the stages of meiosis to the stages of mitosis, which stages are unique to meiosis and which stages have the same events in both meiosis and mitosis?
23. Why would an individual with a mutation that prevented the formation of recombination nodules be considered less fit than other members of its species?
24. Does crossing over occur during prophase II? From an evolutionary perspective, why is this advantageous?
25. List and briefly describe the three processes that lead to variation in offspring with the same parents.
26. Animals and plants both have diploid and haploid cells. How does the animal life cycle differ from the alternation of generations exhibited by plants?
27. Explain why sexual reproduction is beneficial to a population but can be detrimental to an individual offspring.
28. How does the role of meiosis in gamete production differ between organisms with a diploid-dominant life cycle and organisms with an alternation of generations life cycle?
29. How do organisms with haploid-dominant life cycles ensure continued genetic diversification in offspring without using a meiotic process to make gametes?

Explain how hydrogen bonding leads to the properties of cohesion, surface tension and adhesion. hydrogen bonds are weaker than covalent bonds, in liquid water they form, break, and reform easily. Thus, the exact number of hydrogen bonds formed per molecule varies.
