Hierarchy- Taxonomic classification groups organisms according to their relatedness.
Taxonomic traits- are the characters used to classify organisms according to their taxonomic groups. These characters are very important in quantifying the degree of relatedness of species with one another.
Ancestral Traits- are evolutionary traits that are homologous within groups of organisms.
Derived traits- are characters that are present in a species, but absent in an organism, but present in its ancestors. this can be vice versa.
Morphologicaltraits- refer to the set of physical features of living organisms. This can be external or internal morphological traits that are useful for the classification.
Developmental traits- refer to the set of developmental features that can be used for the classification of organisms. Characters that can be observed in living organisms during embryonic development
Physiological traits- are mainly focused on the functional features of the structures. Constructing convergent evolutionary parts among distantly relatedly organisms.
Genetictraits- refer to specific DNA molecules in organisms. The use of genetic sequences in comparing the differences and similarities of organisms is highly useful in delineating organisms.
