We Observe a Frog That Carries Its Babies on Its

question 17

Multiple Choice

We observe a frog that carries its babies on its back away from where the eggs hatched. Here are two questions about this observation:
X- Does the frog do this to move the babies to a place where they will be safer and more likely to survive?
Y- Does the frog have specific morphological traits that enable it to hold and transfer its babies in this way?
Which of the two is an ultimate question?

• A) X, because it considers the adaptive value or function of the trait
• B) Y, because it asks about the developmental mechanisms that influence the components of the animal
• C) Both X and Y, because they look at the immediate and mechanistic causes of the behavior
• D) Neither X or Y, because they both take an adaptive or evolutionary approach to look at the ultimate causes of the behavior
