Lecture 16: Evidence for evolution
The evidence for evolution
- Hierarchical organization of life
- Homology (e.g. 1, 2, lots of bits, 5 rule)
- Genes and genomes (e.g. only one genetic code)
- convergent evolution (e.g. bat wings vs bird wings)
- Embryology (embryos of different creatures are similar)
- Vestigial organs
- Intermediate forms
- Biogeography
- Fossil record
- Evolution in our lifetimes
Hierarchical organization of life
Species are most readily classified as a result of divergence and branching from common
ancestors.
Genes and genomes show homology too
