Fossil data can be used to generate phylogenies that include extinct taxa. Which of the statements indicates how fossil data can be used to refine phylogenies constructed with molecular data? Fossil data can be used to prove which species was the common ancestor of a group of extant taxa. Fossil data can be used to show where speciation events occurred in extant taxa. Fossil data can be used to show convergent evolution in molecular sequences from extant taxa. Fossil data can be used to confirm the time since divergence between extant taxa estimated from sequence data.
