phylogenetics
Evolutionary relationship mapping
Phylogenetics is the study of evolutionary relationships among organisms or genes, typically represented as branching tree diagrams showing common ancestry.
Researchers use DNA sequences, physical traits, or both to reconstruct how species diverged over time: Phylogenetics revealed that birds are living dinosaurs.
The field underpins modern classification and helps trace the origins of diseases.
