Solution

To answer this question, we need to understand the concept of genetic relatedness. Genetic relatedness is often determined by comparing the DNA sequences or the amino acid sequences of different species. The more similar these sequences are, the more closely related the species are likely to be.

The question does not provide specific amino acid sequences for lemurs, gibbons, cows, and pigs. Therefore, we cannot definitively determine which two are the closest relatives based on the information given.

However, based on general knowledge of evolutionary biology, lemurs and gibbons, both being primates, are likely to be more closely related to each other than either is to cows or pigs, which are ungulates (hoofed mammals).

So, the answer would likely be "Lemurs and gibbons". But remember, this is a general assumption based on the classification of these animals and not on specific amino acid sequence data.

If the question is implying that amino acids cannot be used to determine relatedness at all, then the answer would be "None of the above. Amino acids cannot be used to determine relatedness." But this statement is not generally true in the field of evolutionary biology.
