A hyrax is an animal that has been called a rock rabbit and looks like a guinea pig. Fossil records show that hyraxes first appeared on Earth approximately 37 million years ago. As they evolved, some became mouse-sized, while some were the size of a horse. Some eventually adapted to marine life and are related to manatees, and some became grazers and are related to elephants.

Which number would indicate the most recent common ancestor of the hyrax, elephant, and manatee on the section of this mammalian evolutionary tree?

• 1

• 2

• 3

• 4

During the Relationships and Biodiversity lab, simulated pigments from three plant species were compared to those in Botana curus. The results were similar to those represented below.

Based on the results of this comparison alone, is there enough information to conclude which of the other three species is most closely related to Botana curus?

• Yes. Only species X has the same bands as Botana curus.

• Yes. Species Z has only two of the bands that Botana curus has.

• No. Additional tests should be done to test for other chemical similarities.

• No. Other rainforest plant species should be tested.
