Biology 30
BI30-LE2
Examine the significance of evolution as a key unifying theme in biology through the principles, processes and patterns of biological evolution.
SI, DM
Indicators for this outcome
| (a) | Identify common misconceptions (e.g., individuals evolve, natural selection is evolution, evolution is random and evolution is a theory) regarding biological evolution. (K) |
| (b) | Outline the key principles (e.g., descent with modification, fitness as a result of adaptations and struggle for existence) and processes (e.g., natural selection, genetic drift and selective breeding) of biological evolution. (K, STSE, A) |
| (c) | Investigate how humans use selective breeding (i.e., artificial selection) to enhance desirable characteristics in organisms. (STSE, K) |
| (d) | Explain the importance of the concept of the last universal common ancestor (LUCA) in understanding evolutionary relationships among organisms. (K, A) |
| (e) | Interpret cladograms and phylogenetic trees to determine evolutionary relationships among organisms. (S) |
| (f) | Identify historical perspectives and key contributions to the field of evolutionary biology by scientists such as Jean-Baptiste Lamarck, Thomas Robert Malthus, Charles Darwin, Alfred Russel Wallace, Alfred Wegener, f. Theodosius Dobzhansky, Lynn Margulis, Stephen Jay Gould, and E. O. Wilson. (K, STSE) |
| (g) | Discuss how Darwin's observations informed the development of the theory of natural selection as a mechanism of evolution. (K, STSE) |
| (h) | Recognize how the principles of natural selection occur at the level of the individual and may result in the evolution of the population. (K) |
| (i) | Examine how particular selective pressures (e.g., competition, predation, changes in climate, parasitism and pollution) acting on an individual can influence a population over time. (K, S) |
| (j) | Explain how geographic, temporal and behavioural isolation can influence speciation. (K) |
| (k) | Identify concepts (e.g., gradualism versus punctuated equilibrium, convergent evolution, divergent evolution, coevolution, adaptive radiation, mass-extinction and the evolutionary arms race) that are only evident when examining evolution over a multitude of generations extending to geological time. (K) |
| (l) | Examine how scientists use the fossil record, radioactive dating, comparative embryology and homologous and analogous structures as evidence of biological evolution. (K, STSE) |
| (m) | Explore human evolution in relationship to other primates, considering the Out of Africa hypothesis and the agricultural revolution. (STSE, A, K) |
