Although the operation of natural selection requires that genotypes differ in fitness, for some geneticists it seems easier to understand natural selection than fitness. Partly this reflects the fact that the word “fitness” has been used to mean subtly different things. Here I distinguish among these meanings (e.g., individual versus absolute versus relative fitness) and explain how evolutionary geneticists use fitness to predict changes in the genetic composition

I had almost the same question on one of my quizzes but it had one other answer. Mine was,
"The picture below shows the bone structures of whale and bird.
Picture shows similar bone structures of whale and bird.
Based on the diagram, which of these statements is correct about whales and birds?
a
) They have similar food habits.
b
) They move in the same manner.
c
) They share a common ancestor.
d
) They use their limbs to catch their prey."
After doing some research, I found that the correct answer was that they share a common ancestor.
