AP Bio Lizard Evolution Virtual Lab Quizzes
what do the four groups of anoles (trunk-crown, twig, trunk-ground, and grass-bush) represent?
four ecomorphs
which of the following features may differ among different ecomorph groups?
relative tail length
relative hindlimb length
number of toepad lamellae
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..
ecomorphs
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? 1
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? 2
similar adaptations evolved on different islands
