How many blue snakes are there in the population?
How many brown snakes are there in the population?
How many green snakes are there in the population?

Which color(s) of snakes are best suited for the grass and dirt environment?
The blue snakes are most likely to be eaten by birds. What will happen to the blue allele (gene) in the population?

Using the concept of natural selection, explain why the blue snakes went extinct (all died). Mention which color snake(s) better blended in with the grass/dirt.

Using the concept of natural selection explain why the population of snakes shifted to mostly brown snakes. Use the words survive and reproduce.
If there were no birds in the area, would there be a shift in the population to mostly brown snakes?

The Owenoid fish are all different sizes. What causes the differences in the fish size?

What size fish is best suited for the environment?
Which color of snake is more likely to be seen by predators?
Due to the drought the environment is mostly brown dirt. Which color snake is "best fit" for the environment?

What happened to the allele frequency of green snakes in the population?
Why are the large fish not eaten by the sharks?
Predict what will happen to the number of medium sized fish.
