Where does the most evidence for evolution comes from?

The most compelling evidence, as well as the greatest amount of observational data to support the evolutionary model and aid in its refinement, comes from genetics and comparative genomics. The genomic record (the complete library of all sequenced genomes and the genes they contain) is by far the most complete record of evolution that we have at our disposal. Additionally, the fossil record can be used to test and verify hypotheses regarding timing of emergence, behaviours and morphology of ancestral forms.
