Postulate #1 Overpopulation
- The ability of a population to expand is infinite, but the ability of an environment to support a population is always finite
- Environment Constraints Population Growth:
- ex. The Galapagos drought of 78'.
- The drought affected seed availability (large, tuff).
- Birds with beaks large enough to eat the seeds were most likely to survive.
- Organism's within populations vary, and this variation effects ability of organisms to survive and reproduce.
