- Evolution is the change in an allele frequency over time
- Natural selection is one explanation of how evolution functions
- Selection Pressure refers to factors such as food, predators, diseases and competition on a species which results in the frequency of an allele to alter within a gene pool
- Gene Pool refers to the total number of all alleles within a population at a given time.
Types of Competition:
- Intraspecific Competition: Competition between the same species
- Interspecific Competition: Competition between different species
Over Production
- Over production is the result of a high birth rate resulting in intraspecific pressures
- Those with the allele which is advantageous provide them the limited resources to survive
- Therefore the allele is passed on
