Tuesday- Today we included the topic of the origin and history of life.
In today's lesson we talked about:
- Biogenesis in contrast to abiogenesis with emphasis on the experiments used to support both ideas.
- Early atmosphere hypotheses and experiments.
- How the early conditions affected the type of organism that developed (anaerobic and prokaryotic).
- Evolution of eukaryotic and aerobic organisms.
- The importance of the environment in selecting adaptations.
Wednesday- Today we examined the development of the theory of evolution by natural selection including: fossil and biochemical evidence.
We talked about:
- Historical development of the theory of evolution by natural selection.
- Fossils-relative and absolute dating methods
- A discussion of what can be inferred from patterns in the fossil record.
- Biochemical similarities.
Thursday- The only differences today was that we learned about the mechanisms of evolution and the applications (pesticide and antibiotic resistance).
We discussed:
- How variations provide material for natural selection.
- The role of geographic isolation inspeciation.
- Discuss the evolutionary selection of resistance to antibiotics and pesticides in various species.
Friday- Today we analyzed the classification of organisms according to their evolutionary relationships, and the historical development and changing nature of classification systems.
Notes today were:
- Originally two kingdoms (plants and animals). More kingdoms added as knowledge of the diversity of organisms increased.
- Development of the seven level classification system (KPCOFGS) and binomial nomenclature
- Evolutionary phylogeny, DNA and biochemical analysis, embryology, morphology
- Interpret phylogenetic trees
