Item CA010002: If the DNA of jellyfish and insects is more similar than the DNA of jellyfish and plants, then jellyfish and insects share a more recent common ancestor than jellyfish and insects.
If the DNA of jellyfish and insects is more similar than the DNA of jellyfish and plants, what is a reasonable conclusion about the common ancestors of these three groups?
- Jellyfish and insects have a common ancestor, but jellyfish and plants do not.
- Jellyfish and plants have a more recent common ancestor than jellyfish and insects.
- Jellyfish and insects have a more recent common ancestor than jellyfish and plants.
- Similarities in DNA cannot provide information about the common ancestors of jellyfish and insects because jellyfish and insects do not share a common ancestor.
