Phylogeny
uses communal ancestry to group organisms and further nest them into bigger and
bigger groups. This is also a study of evolutionary relationships among
organisms. Visible characteristics such as anatomical and behavioral traits, as
well as biochemical (enzymes, proteins, pigments, etc.) and genetic traits
(nucleotide sequences) that need more modern techniques to detect.
