Correct answer is (c) Sampling bias is involved

The best explanation: There is no sampling bias involved, which helps to mend the gaps in real fossil records. Therefore, they have become favorite and sometimes the only information available for researchers to reconstruct evolutionary history. The advent of the genomic era with tremendous amounts of molecular sequence data has led to the rapid development of molecular phylogenetics.
