Question

scientists compile many pieces of evidence to infer evolutionary relationships. here is one such piece of evidence.
these pictures show the mouths of three different aquatic vertebrates: a great white shark, a piranha, and a lamprey.
great white shark piranha lamprey
how does this evidence support the claim that great white sharks are more closely related to piranhas than to lampreys? complete the paragraph.
great white sharks and lampreys have similarities in their mouths than great white sharks and piranhas have. this suggests that great white sharks and have more similar dna and evolved from a more common ancestor.

Explanation:

The first blank should be "fewer" because the claim is that great - white sharks are more closely related to piranhas. If they are more closely related to piranhas, they should have fewer similarities with lampreys. For the second blank, it should be "piranhas" as we are comparing the relationships. And for the third blank, "recent" makes sense because more closely related species share a more recent common ancestor.

Answer:

Great white sharks and lampreys have fewer similarities in their mouths than great white sharks and piranhas have. This suggests that great white sharks and piranhas have more similar DNA and evolved from a more recent common ancestor.
