question 3

Multiple Choice

Cytochrome c is a molecule used in the electron transport chain of many organisms. Data regarding differences in the amino acid sequence of cytochrome c show that the sequence in a moth differs from a turtle by 15 about amino acids, while a moth differs from a human by about 30 amino acids. Therefore,

• A) this is sufficient evidence to prove the moth is related more to the human than the turtle.
• B) turtles evolved before moths.
• C) there is no evolutionary relationship between moths, snakes, and humans.
• D) in addition to anatomical similarities and fossil data, this provides additional evidence for determining the relatedness between these organisms.
