Question
Among mammals, the presence of lungs is a(n) Blank______.Multiple choice question.shared derived character, representing an evolutionary reversal to an ancestral character stateshared derived character because it likely evolved in the most recent common ancestor of mammalsancestral character because it is found only in mammalian vertebratesancestral character because it is present in other vertebrate animals and likely evolved prior to the common ancestor of mammals
Solution
The correct answer is: "ancestral character because it is present in other vertebrate animals and likely evolved prior to the common ancestor of mammals". This is because lungs are not unique to mammals; they are also found in other vertebrates like birds and reptiles. Therefore, the presence of lungs likely evolved before the common ancestor of mammals.
