Mystery Science: Unit 3, Lesson 3 (natural selection)

1. Why do green anoles climb trees?

• To be able to see far away for predators (animals that might eat them).
• To find more bugs to eat or escape from animals trying to eat them.
• Green anoles do not climb trees.

2. What happened to the green anoles when the brown anoles arrived on Lizard Island?

• Some green anoles were eaten.
• Some green anoles attacked the brown anoles.
• Nothing happened, the anoles are the same species and get along with each other.

3. Which green anoles were most likely to be caught by the brown anoles?

• The green anoles that had fewer sticky toe pads weren’t as good at climbing to they were more likely to be eaten by the brown anoles.
• The ones that were bad at camouflage (blending in to their surroundings).
• The brown anoles all have more sticky toe pads than then green anoles, so they were all likely to get caught.

4. Why is the group of baby green anoles better climbers than the group of parent green anoles?

• The baby green anoles are not better climbers than the group of parent green anoles.
• The baby green anoles have more sticky toe pads that the parent group of green anoles.
• The baby green anoles are better climbers because they need to get away from the brown anoles until they become adults.

5. Can selection happen without the help of people?

• yes
• no
