If two species have many amino acid differences, are they closely or distantly related? Explain how scientists know this.
devlian [24]
Different amino acids means difference DNA sequences, which means they are distantly related.

Further understanding: if you look at identical twins, they are closely related to each other because they have almost the same DNA, which will code for the same amino acids, which will lead to the same phenotype or appearance.

To summarize, the greater the amino acid differences the less related they are and vice versa

Hope that helps
