They work best when they can be “calibrated” with other markers of time, such as fossils with known ages and placements.

Synapomorphy

A trait that is shared by two or more taxa and their most recent common ancestor, used to infer evolutionary relationships.

Phylogenetic Methods

Techniques used in biology to infer the evolutionary relationships and history among different species or genes.
