Terminology you should know
gradualism . actualism . microevolution . macroevolution. missing links . punctuate equilibrium . Hopeful Monsters . homeotic mutants . pre-adaptation . functional shift . ABC-model . heterochrony . C4 photosynthesis .
Concepts you should know, be able to explain, and remember
You can explain, how gradualism tries to explain macroevolution, and what the weak point is
You can explain using examples, what the concept of preadaptation and functional shift means
You can explain using examples, what heterochrony is and why it is relevant for evolution
- You can explain what C4 photosynthesis is, why it is a challenge for evolutionary theory, and how its genesis currently explained
To think about
- Why did many genes duplicate, when plants conquered terrestrial habitats?
- How would a mutation in the promoter of a B-gene that causes precocious expression, change the flower?
- Can you think of a simple scenario explaining that DFR (driving antocyanin) becomes expressed in the microsporophylls)?
- Can you tell, what the functional shift of oxylipin synthesis was, when predatory insects arose?
To read and deepen
- Evolution of oxylipin pathway can be explained by gene duplication and functional diversification. Lee et al. 2008 (via KIT-Lizenz)
- Heterochrony can explain evolution of leaf shape. Cartolano et al. 2015 (open access)
