Question

Quizplus · Accepted Answer

Comparing the genomes of living organisms can reveal their evolutionary relationships because organisms with more similar DNA sequences are more closely related. This is because these similarities likely arose due to a common ancestor. Comparing anatomical features or embryological development can also be used to infer evolutionary relationships, but these characteristics can be more variable and subjective. The fossil record can provide information about the past history of organisms, but it may not give insight into their current relationships.
