- Adaptations
- Overproduction
- Overproduction occurs when species produce more offspring that can survive.
- Competition occurs individuals compete for limited resources such as food, water, and space.
- Competition
- Natural Selection
- Both zebras and giraffes live in the same ecosystem and they both eat leaves.
- Variation is the mechanism by which each individual has a unique combination of inherited traits.
- Speciation

- These beetles are of the same species, but they have variations which cause them to have different colors.
- Adaptation is the mechanism by which organisms adjust and adapt to their new environment.
- The grey caterpillar was born with a unique color that help it blend better and adapt to the environment.
- The mice that blend into the environment have a better chance of survival, which will allow them to reproduce offspring which will have the same favorable trait
- Natural selection is the mechanism by which organisms that are best adapted to the environment survive and reproduce more than others.
- Speciation is the mechanism by which new species form during the course of evolution.
- Through evolution, thousands of different bird species have formed.
