move the correct answers into the boxes provided. not all options will be used.

claim\tevidence
the early-stage embryos of vertebrates suggest a common ancestry.\ttwo dashed boxes

options:

• tails get shorter in animals that live on land or fly.
• all vertebrate embryos have gill pouches and long tails.
• the embryos of vertebrates have a large head and limb buds.

Explanation:

To support the claim that early - stage vertebrate embryos suggest a common ancestry, we need evidence that shows a shared feature among all vertebrate embryos.

• "Tails get shorter in animals that live on land or fly" describes a change in tails related to habitat, not a shared early - stage feature.
• "All vertebrate embryos have gill pouches and long tails" shows a common set of features (gill pouches and long tails) in all vertebrate embryos at an early stage, which supports the idea of a common ancestry.
• "The embryos of vertebrates have a large head and limb buds" describes some features but not a feature that strongly points to common ancestry as the shared gill pouches and long tails do.

Answer:

The correct evidence to move into the boxes for the claim "The early - stage embryos of vertebrates suggest a common ancestry" is:

• All vertebrate embryos have gill pouches and long tails.
• The embryos of vertebrates have a large head and limb buds. (Note: Among these, "All vertebrate embryos have gill pouches and long tails" is the most direct evidence for common ancestry as it shows a shared trait across all vertebrate embryos in early stages. If we consider the two boxes, these two can be used as they both describe shared embryonic features, with the first being more specific to common ancestry - related shared traits.)
