- 1. organisms produce more offspring than will survive to maturity
- 5. change in genetic composition of a population, often results in new species
- 6. Some individuals survive longer & reproduce more than others do.
- 12. The traits of those individuals that survive & reproduce will become more common in a population.
- 15. changes in environment which may give rise to adaptations
