Question

Describe how DNA evidence might be used to confirm scientists' conclusions about any relationship between birds and seals?

Answer 1

Scientists could compare the DNA of the two species to confirm an evolutionary relationship.

Explanation: I used the Cells and hereditary book

Answer 2

All DNA is remarkably similar, but some more than others. Humans' DNA would be closer to other mammals' than it is to, say, a bird. Using DNA shows how varied an animal really is from another. Specific parts of the DNA code for different things, so you might see a similar structure for wings and flippers.
