Challenge Problems

Push your limits with challenges.

Question 1

Given a set of four characteristics, construct a simplistic cladogram showing the relationships between three organisms (a bird, a reptile, and a mammal). Explain your reasoning behind the placement of each organism.

💡 Hint: Use shared traits to map how these organisms are connected.

Question 2

Discuss how the inclusion of both morphological and molecular data enhances the robustness of cladistic analysis. Give examples of when one type of data might lead to different conclusions than the other.

💡 Hint: Think about cases where looks can be deceiving in nature!
