- Variation
- Competition
- Selective Pressure
- Species of ants resides in a backyard that has very dark green grass. There is a variation of colour within the ants. Most of the ants are black and very few ants are green.
- Adaptation
- The black ants dominate the backyard as the green ants remain only a few as they are very visible for predictors to eat. This also creates competition for food and resources for the ants.
- Differential Reproduction
- A few months later, the very sunny weather turns the dark green grass into lighter green. The crows now feed on the black ants as they are easier to spot.
- Survival
- Overtime the population of the black ants all shorten immensely. However, the green ants managed to maintain their population and survive.
- As the time goes on, the green ants are given a selective advantage and are now capable of reproducing much more offsprings to pass on the heritable green colour than the black ants.
- The green ants now dominate the yard as they continue to survive. There still are a few black ants, however will not be the same amount as before.
