Step-by-step explanation:
Claim: Based on the molecular evidence from Station 3, a wallaby is most closely related to a kangaroo.
Evidence: The molecular data from Station 3 shows that the wallaby and kangaroo share a high degree of genetic similarity. They have similar DNA sequences and protein structures, indicating a close evolutionary relationship.
Reasoning: Molecular evidence, such as DNA and protein sequences, provides a more accurate and detailed understanding of the evolutionary relationships between organisms than physical traits alone. The genetic similarity between the wallaby and kangaroo suggests that they share a common ancestor and have diverged relatively recently in evolutionary history. Therefore, based on the molecular evidence from Station 3, we can conclude that the wallaby is the organism that is most closely related to the kangaroo.
