The table below shows the number of differences observed when the amino acid sequences of cytochrome c in different organisms are compared. Which of the following conclusions is best supported by this data?




Cytochrome c is a protein needed for aerobic cellular respiration. It is found in nearly all organisms. The amino acid sequence of cytochrome c can be different in different organisms depending on the sequence of DNA. The table below shows the number of differences observed when the amino acid sequences of cytochrome c in different organisms are compared. Which of the following conclusions is best supported by this data?




Horses and whales are the most closely related organisms shown.




Silk moths and snakes are the most closely related organisms shown.


Whales and penguins evolved more recently than any of the other organisms


Snakes are more closely related to silk moths than to chickens.
