modern evolutionary theory (classical and synthetic), including Ch. Darwin, R. Wallace, T.
Dobzansky, E. Mayr
2. Know the four basic statements and core ideas of the evolutionary theory as introduced by
Darwin in 1859.
3. Know which further ideas and statements have been added to the theory in the 1940s by E.
Mayr and T. Dobzshansky in the so-called “synthetic theory”
4. Understand and be able to interpret the phrase “survival of the fittest” in the context of the
evolutionary theory; what does “fit” mean in a Darwinian sense?
5. What is meant in the evolutionary theory by the term “speciation”?
6. How is a species defined according to the modern evolutionary theory?

7. Know examples of factors and events which can lead to speciation
8. Know the difference between allopatric and sympatric speciation. Know one or two
(textbook) examples for each of these two.
9. Rehearse the meaning and examples of prezygotic as well as postzygotic reproductive
barriers. How do and can they contribute to speciation?
10. Rehearse examples of important geological, cosmic and tectonic events on planet Earth
which are considered to may have contributed to species separation, speciation or
extinction
(Key words: Pangaea super continent, Galapagos island, Hawaiian islands, Alvarez
hypothesis, Madagaska, rift valley)
11. Understand the impact of continental drift and plate tectonics to the evolution of life on
planet earth
12. Understand the term “selective pressure” in the context of adaptation as part of the
evolutionary theory
13. Understand the term “artificial selection” and how this relates to the rise of the new
phenotypes and species
14. Understand why and how reproductive isolation can trigger speciation
15. Know the difference between microevolution and macroevolution
16. Rehearse the outcomes of different selective pressures put upon a population and know the
names of the different forms of selection. What is the difference between diversifying and
directional selection?
17. Know examples of human activities which can lead to reproductive isolation of species
