What do the four groups of anoles (trunk-crown, twig, trunk-ground, and grass-bush) represent?

Why did you need to calculate relative hindlimb length rather than absolute hindlimb length?

to control for the effects of body size when making comparisons

Species that belong to the same ecomorph group are similar in appearance and occupy similar habitats. This suggests that species living in similar habitats evolved similar traits—in other words, the traits are adaptations. Which of the following observations supports this conclusion?

Anole species living high in the canopy have larger toepads and can cling to smooth leaves better than species found on tree trunks and on the ground.

Based on what Dr. Jonathan Losos said, why have different lizard species evolved to occupy different parts of the habitats?

to minimize competition for food and other resources between different species.

On Puerto Rico and Hispaniola, you find the same:

Based on what you have learned so far, what is the most likely explanation for why the same ecomorphs evolved on both Puerto Rico and Hispaniola?

Both islands have similar habitats.

The tree is more consistent with which of the following hypotheses:

The same types of anole lizards evolved independently on each of the islands.

Which of the following statements is supported by the evidence from the tree?

The anole species on puerto rico and hispaniola evolved from a common ancestor.

Which of the following statements is supported by the evidence from the tree?

Similar adaptation evolved on different islands

According to Dr. Losos, the independent evolution of similar species on the different islands is an example of which of the following processes?

Convergent evolution

In this experiment, researchers placed a pair of lizards from Iron Cay, which has large trees, in an experimental island, which has only small bushes and grass. After several generations, they measured the leg length of 10 lizards from each site. Which group of lizards had longer legs on average?

The ones on iron cay

Which of the following statements accurately describes the results of the experiment

On average, the lizards on the experimental island seem to have shorter legs than the lizards on iron cay.

Anolis sagrei, the lizard species used in this experiment, is a trunk-ground anole. Which of the following statements about trunk-ground anoles is accurate? (You can read more about the different anole types under the "Reference" tab.)

They have long legs adapted to perching on broad tree trunks and running fast on the ground.

The group of Anolis sagrei on the experimental island had shorter legs on average than the A. sagrei on Iron Cay. What is a likely explanation for this finding?
Continue

There is a selection for shorter legs on the experimental island and for longer legs on iron cay

The data from this experiment provides evidence that supports which of the following claims.

In different environments, different variations in traits provide an advantage
