A similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.
<h3>What are recrystallization and replacement modes of preservation?</h3>
Recrystallization is a mode of preservation of fossils in which the internal structure of the fossils is changed by addition of more minerals to form larger crystal of the same material.
Replacement is a mode of preservation in which new material replaces the original material in the fossil.
In both methods of preservation, delicate tissue and organs are not preserved.
Therefore, a similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.

The ability to analyze DNA via DNA sequencing and other molecular analysis techniques has made it easier to group molecules into categories that represent lines of phylogeny.
Phylogeny is based on similar physical and genetic characteristics between organisms. Before such techniques, scientists were able to discern and group organisms only on the basis of their morphology, or their physical shape or appearance.
