Describe processes and patterns of evolution.
Describe processes and explain patterns of evolution.
Describe processes and discuss patterns of evolution.

3. Explanatory Notes Processes of evolution are limited to
ways in which speciation occurs (sympatric, allopatric)
reproductive isolating mechanisms that contribute to speciation (geographical, temporal, ecological, behavioural, structural barriers, polyploidy)
the role of natural selection.

4. Patterns of evolution will be selected from: convergent evolution, divergent evolution (including adaptive radiation), co-evolution, punctuated equilibrium, gradualism.

5. Prior Knowledge Required
Describe the key ideas that underpin the theory of evolution
Understand the concept of natural selection and different types, incl fitness, adaptation
Define the terms species and population
Describe gene and allele frequency
Define speciation, gene flow, genetic equilibrium
Identify sources of genetic variation in a gene pool
Identify agents of change that lead to change in a gene pool
Define the terms genetic drift, the founder effect and the bottleneck effect
