Study Notes
Natural Selection
- Natural selection is the process by which populations of living organisms adapt and evolve over time in response to environmental pressures.
- It is a key mechanism of evolution that leads to the survival and reproduction of individuals with advantageous traits.
Requirements for Natural Selection
- There are three main requirements for natural selection to occur:
- Variation in a population (genetic variation)
- Heritability of the variation
- Differential reproduction rates based on the variation
Examples of Natural Selection
- Antibiotic resistance in bacteria is an example of natural selection, where bacteria that are resistant to antibiotics are more likely to survive and reproduce.
- The development of pesticide-resistant pests is another example, where pests that are resistant to pesticides are more likely to survive and reproduce.
