This beetle species has two colors, brown and green. These beetles are normally found in muddy fields where there are patches of green grass as well as patches of brown dirt. Both the green and brown beetles have places in these fields where they are camouflaged from predators.

But there is a very dry summer and all of the green grasses turn brown. Now, the fields where the beetles live are all brown. The green beetles are now much easier for the predators to see.

Over many months, predict how this population of beetles might evolve through natural selection. Make sure to include all of the principles of natural selection (VCAR).

Principles:

Variation: slight differences amongst individuals in the population

Competition: for an environment's resources

Adaptation: the advantage some members of the population have over others in the population

Reproduce: organisms that survive will increase in number

**Title: Evolution of Beetle Population through Natural Selection**

**Introduction:**
This beetle species has two colors, brown and green. These beetles are normally found in muddy fields where there are patches of green grass as well as patches of brown dirt. Both the green and brown beetles have places in these fields where they are camouflaged from predators.

**Environmental Change:**
But there is a very dry summer and all of the green grasses turn brown. Now, the fields where the beetles live are all brown. The green beetles are now much easier for the predators to see.

**Predicting Evolutionary Changes:**
Over many months, predict how this population of beetles might evolve through natural selection. Make sure to include all of the principles of natural selection (VCAR).

**Principles of Natural Selection:**
- **Variation:** slight differences amongst individuals in the population
- **Competition:** for an environment's resources
- **Adaptation:** the advantage some members of the population have over others in the population
- **Reproduce:** organisms that survive will increase in number

**Analysis:**
Using the principles of natural selection, discuss the possible evolutionary changes in this beetle population given the new environmental conditions.

**Discussion Prompt:**
Enter your predictions and explanations in the text box below. Make sure your answer demonstrates your understanding of the principles of natural selection.
