Genetic changes in a population over time
- Causes of changing allele frequencies in a population’s gene pool, including environmental selection pressures, genetic drift and gene flow
- Mutations as the source of new alleles
- Biological consequences of changing allele frequencies in terms of increased and decreased genetic diversity
- Manipulation of gene pools through selective breeding programs
Changes in species over time
- Changes in species over geological time as evidenced from the fossil record: faunal (fossil) succession, index and transitional fossils, relative and absolute dating of fossils
- Evidence of speciation as a consequence of isolation and genetic divergence, including Galapagos finches as an example of allopatric speciation and Howea palms on Lord Howe Island as an example of sympatric speciation
