1. Evolution is one of the unifying concepts of modern biology. Explain the mechanisms that lead to evolutionary change. Describe how scientists use each of the following as evidence for evolution.
a) Bacterial resistance to antibiotics
b) Comparative biochemistry
c) The fossil record
2. Discuss the significance of each of the events listed below in the evolution of living things.
a) Primoridial reducing atmosphere
b) Origin of photosynthesis
c) Increase in atmospheric oxygen and the development of the
d) Origin of eukaryotes
3. Define, discuss, and give an example of how each of the following isolating mechanisms contributes to speciation in organisms.
a) Geographical barriers
b) Ecological (including seasonal) isolation
c) Behavioral isolation
4. Evolution is one of the unifying themes of biology. Evolution involves changes in the frequencies of alleles in a population. For a particular genetic locus in a population, the frequency of the recessive allele (a) is 0.4 and the frequency of the dominant allele (A) is 0.6.
a) What is the frequency of each genotype (AA, Aa, aa) in this
population? What is the frequency of the dominant phenotype?
b) How can the Hardy-Weinberg principle of genetic equilibrium be
used to determine whether this population is evolving?
c) Identify a particular environmental change and describe how it
might alter allelic frequencies in this population. Explain which
condition of the Hardy-Weinberg principle would not be met.
