Why is the study of evolutionary relationships based not only on fossils but also on structure and genetic information?

Answer and explanation

Correct answer: Because different kinds of evidence together give more reliable conclusions

Evolutionary conclusions are stronger when independent lines of evidence agree. Fossils provide a record of organisms and forms that existed in the past, although that record is incomplete. Comparative anatomy reveals homologous structures, while genetic similarities can indicate shared ancestry and relative relatedness. Combining these sources reduces the limitations of relying on only one type of evidence. Therefore option A is correct; the other choices wrongly reject useful evidence or deny its relevance.
