Step 1
Sampling DNA and identifying similarities between the animals listed
Answer
To measure the extent of the evolutionary relationships, sampling DNA is a highly effective method. By analyzing the genetic material from the platypus and the other animals, we can identify similarities and differences in their DNA sequences. This method allows us to determine how closely related these species are on the evolutionary tree. Genetic analysis provides insight into evolutionary lineage and can highlight shared ancestry, which is crucial in understanding their relationship.
