A team of scientists discovered what they believed to be a new species of fish. Using gel electrophoresis, they analyzed samples of DNA from the newly discovered fish and from four known species of fish. The diagram below shows the bands of DNA from the gel electrophoresis.

37. Use the results of the gel electrophoresis to: Determine if the newly discovered fish is, in fact, a new species of fish. Identify which of the known species is most closely related to the newly discovered fish. Explain how the relatedness of the fish can be determined by examining the location

of the bands in the electrophoresis gel. Describe other types of evidence that scientists can use to determine relationships

between species.
