The analysis of proteins (particularly enzymes), DNA and RNA have provided extremely powerful confirmation of the fosil record.

Base (building block) sequences change from species to species in the same protein or gene sequences.  The change in a particular protein or nucleic acid is a measure of the divergence of those species.  The fosil record also shows the divergence of species.

Comparing the evolutionary trees generated from fosil evidence with the tree results gathered from the biochemical analysis of existing species yields compatible results that confirm the correctness of the fosil evidence.

The same results from two very different techniques. When both biochemistry and the fosil record provide the same results for the divergence of existing species, then the need for falsifiablity is satisfied as is the requirement for prediction.
