Study Notes
Autapomorphy and Related Terms
-
Autapomorphy: A derived trait unique to a specific taxon, providing a distinctive feature for identification.
-
Apomorphy: Reflects a change from the ancestral form, an innovation critical for determining clade membership.
-
Synapomorphy: A shared derived trait that differentiates a clade from other organisms, essential for phylogenetic classification.
-
Plesiomorphy: An evolutionary trait homologous within a group but not unique, limiting its utility for defining the group's characteristics.
-
Homoplasy: Traits that appear similar across species but arise from different evolutionary paths, highlighting characteristics that are not inherited from a common ancestor.
-
Symplesiomorphy: An ancestral trait shared among modern groups, often less useful for assessing recent evolutionary relationships due to its ancient origins.
