How are fossils, comparative
morphology, patterns of development,
and molecular sequences used as
evidence of evolution?

Explanation:

Molecular similarities provide evidence for the shared ancestry of life. DNA sequences comparisons can show how closely species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

hope it helps

By studying both living organisms and the fossils of their extinct ancestors, zoologists and paleontologists can draw conclusions about their origins. ... Some of the strongest evidence of evolution comes from comparative studies—comparing structural similarities of organisms to determine their evolutionary relationships

In general, the relatedness of groups of organisms is reflected in the similarity of their DNA sequences—exactly the pattern that would be expected from descent and diversification from a common ancestor. DNA sequences have also shed light on some of the mechanisms of evolution.
