Question

1. You are studying the amino acid sequence of a protein shared by four organisms. You want to know which organism is most closely related to organism A. You have data that shows the number of amino acid differences between organism A and each of the other organisms. Study the data in the chart and use it to answer Question 1.

1.Which organism does this data suggest is most closely related to organism A?

organism B
organism C
organism D

Answer 1

As another user previously said, the higher degree of difference between two organisms can be correlated to their degree of evolutionary separation.

Higher number of differences = lower degree of similarity = less related
