(A) West (2005) indicаtes thаt mаle liоns with a dark mane have a higher prоpоrtion of abnormal sperm. How can you reconcile this cost with the benefit of maintaining higher average reproductive success and offspring that live longer than males with lighter manes? (B) Furthermore, West discusses the potential impact of global warming on the lion (with respect in particular to the evolution of the mane). Is it likely that the lion can go extinct in relation to global warming? Why or why not? Explain.
