Study Notes
Reconstructing Evolutionary History: Fossils, Morphological Data, and Molecular Data
- Fossil record is incomplete, especially for invertebrates, due to soft tissue decomposition
- Radiometric dating methods, like carbon 14, used to determine fossil age
- Morphological data includes homologous traits (good for evolutionary history) and analogous traits (not useful for evolutionary history)
- Molecular data, such as DNA sequences, is the most important for reconstructing evolutionary history
- Molecular clock approach uses DNA sequences to approximate when evolutionary events occurred
- Neutral theory suggests that a lot of evolutionary change is due to neutral mutations and genetic drift
- Phylogenetics is the study of evolutionary relationships between organisms
- Phylogenetic trees represent evolutionary history graphically
- Sister taxa directly evolve from a common ancestor
- Shared derived traits in phylogenies indicate close relatedness
- Ancestral and derived characters are used to differentiate shared traits in phylogenetic analysis
- Synapomorphies, or shared derived traits, are used to group organisms in monophyletic groups
