Darwin’s thoughts on Natural Selection explained a lot about evolution, but…

- Overproduction
- Competition
- Variations & Adaptations
- Natural Selection
- Speciation
most species produce far more offspring than can survive.
Overproduction
since living space and food are limited, offspring must compete for resources.
Competition
individuals that have favorable variations/adaptations will have a greater chance of living long enough to reproduce.
Variations & Adaptations
organisms with variations that make them better adapted to their environment survive and reproduce.
Natural Selection
Accumulated changes become so big that the result is a new species.
