Quizplus · Accepted Answer

DNA sequence similarity is the most direct and accurate way to measure the relatedness of two DNA molecules and the organisms from which they came. This is because DNA sequence similarity reflects the degree of shared ancestry between two organisms, with closer relatives having more similar DNA sequences. Vestigial traits and homologous traits can also provide information about relatedness, but they may not be as precise or easily quantifiable as DNA sequence similarity. Amino acid sequences are derived from DNA sequences, but they may be subject to more variation and complexity than DNA sequences, particularly in cases of convergent evolution or functional divergence.
