The researchers bought samples of whale meat—all labeled simply as kujira, the generic japanese term for whale meat—from markets in japan and sequenced dna from these samples. they compared their data with sequences from known whale species. because subspecies of whales from different populations differ genetically, the researchers were able to analyze the genetic variation in their samples and learn the location from which the whales were likely captured. these results would indicate if illegal whale meat was being sold. drag each statement under the step in the scientific method that it demonstrates.
