Signature sequences identify groups of organisms
Phylogenetic
The phylogenetic tree is used for the study of evolutionary Biology. The phylogenetic tree is a symbolic diagram that is meant to represent the similarity and differences of different species for comparison with common evolutionary relatives.

Phylogenetic Constraint is like a basic body plan. It can be modified (what evolution does) but it can't be fully changed. Vestigial features (things like the human appendix which is a remnant of our ancestors, but is no longer used) provide evidence of common ancestry and phylogenetic constraint. :)

The phylogenetic system of classification was proposed by the German biologist and naturalist, Ernst Haeckel, in the 19th century. He aimed to group organisms based on their evolutionary relationships and common ancestry rather than just physical similarities.
