Physical characteristics.

Reason: morphology is the traditional basis for trees and typically refines rather than radically overturns relationships. In contrast, DNA sequencing, newly found fossils, or discovery of new species often introduce new, independent lines of evidence that frequently cause larger changes in phylogenetic trees.
