How DNA evidence might be used to confirm scientists conclusions about any relationships between birds and seals?

Why do scientists keep track of populations?
By analyzing all this data, scientists can learn new ways to help control animal populations, determine what impact development might have on an animal population, and determine if there are enough individuals of a particular species in an area to allow for reproduction.
How might scientists determine what kinds of animals early people ate?
