SCI 115 Week 8 Lizard Evolution Lab.

QUESTION 1

1. "According to the phylogenetic tree in this virtual lab, all anole lizards (genus Anolis) are more closely related to one another than they are to Leiocephalus carinatus"

  True

  False

   

QUESTION 2

1. "Based on this phylogeny, lizards of the same body type tend to be more closely related to one another than to lizards of different body types? "

  True

  False

   

QUESTION 3

1. "In general, lizards on the same island are more closely related to one another than to similar-looking lizards from other islands? "

  True

  False

   

QUESTION 4

1. The phylogentic tree is most consistent with which of the following hypotheses:

 

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

 

Each lizard type evolved once on one of the islands and then migraded to the other islands where it evolved into different species

 

"Each lizard type evolved on the mainland and was brought to each of the islands, where it evolved into different species"

 

All species of lizards appeared at exactly the same time on each of the islands.

   

QUESTION 5

Anolis coelestinus is the oldest anole species

   

QUESTION 6

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

 

similar adaptations evolved on different islands

 

new species evolve every few thousand years

 

similar species evolved in very different habitats
