A scientist used the аminо аcid sequence оf cytоchrome c in different species to consider evolutionаry relationships. The data below summarize the number of differences in the amino acid sequences of cytochrome c found in selected species. Differences in the amino acid sequences of cytochrome c found in selected species Species Compared Number of Differences Humans - Chimpanzees 0 Humans - Rhesus monkeys 1 Humans - Horses or donkeys 7 Humans - Cows or pigs or sheep 7 Humans - Rabbits 7 Mammals - Birds and reptiles 10-15 Mammals - Fish 18-20 Animals - Plants 45-48 Interpretation of the data supports which of the following phylogenetic trees? I. A phylogenetic tree with a single common ancestor and two branches. The first branch is rabbits. The second branch has two branches. The first is rhesus monkeys, and the second branch splits into chimpanzees and humans. II. A phylogenetic tree with a single common ancestor and two branches. The first branch is horses. The second branch has two branches. The first is rhesus monkeys, and the second branch splits into chimpanzees and humans. III. A phylogenetic tree with a single common ancestor and two branches. The first branch is humans. The second branch has two branches. The first is pigs, and the second branch splits into chimpanzees and rhesus monkeys.
