Study Notes
Natural Selection
- Natural selection requires a large population to cause evolution
- Offspring must resemble their parents more than they resemble other members of the population (heredity)
- Differential success is necessary for natural selection to occur
Evolution
- Evolution helps make sense of taxonomy, fossil record, biogeography, anatomy, and physiology
- Genomes contain old and broken copies of genes (pseudogenes)
- Examples of pseudogenes:
- Taste receptor in pandas (lost the gene for tasting meat)
- Sweet receptors in cats (lost due to meat-based diet)
Applications of Evolutionary Principles
- Evolutionary principles help us understand ourselves and other cultures
- Problem-solving techniques inspired by evolution are used in other fields, such as:
- Racing car design
- Cybernetics
