Question

Your classmate shows you the two groups of lizards shown below—each made within the Evolutionary Evidence lab—and asks if you can figure out how she made them. Which of the following is most likely? (Hint: Imagine the circles you'd draw around lizards with shared traits, as you did in Exercises 2-4, and consider what the pattern of circles signifies.)

A.) The lizards in Group A were independently designed; the lizards in Group B were produced by descent with modification from a common ancestor.

B.) The lizards in Group A were produced by descent with modification from a common ancestor; the lizards in Group B were independently designed.

C.) The lizards in both Group A and Group B were produced by descent with modification from a common ancestor.

ral b is more likey to be widespread among other pimate species because it is older Submit Q6.

Q7. Each of the following graphs shows a hypothetical relationship between the predicted order of trait appearance based on trait nesting (y-axis) and the actual order of appearance in the fossil record (x-axis), for a number of traits among a group of species. Which graph would provide the best evidence that these species arose by descent with modification from a common ancestor?

Explanation / Answer

Ans: C. The lizards in both groups A and B were produced by descent with modification from a common ancestor.

In group A, all lizards have body without spots, two lizards have neck bag and one lizard is modified without having it. This is the same in the trait of spine on the tail and head region. They all look alike as derived from a common ancestor.

In group B, they share common characters with modifications in one lizard among 3.
