Shared derived traits are called ______ .

Question

BlackTom AI · Accepted Answer

The question asks for the term used when traits are shared by members of a group due to derived characteristics. 
Option a: heteromorphies. This term is not standard in cladistics for shared traits and would be considered incorrect because it does not describe derived shared characters.
Option b: synapomorphies. This is the correct term. Synapomorphies are shared, derived characters that define monophyletic groups and indicate common ancestry. They distinguish clades by characters that evolved in a most recent common ancestor and are inherited by its descendants.
Option c: symplesiomorphies. These are shared ancestral traits, not derived ones. They can be common to multiple groups simply because the trait was present in a distant ancestor, so they do not define a clade.
Option d: paraphylies. This term refers to a grouping that includes a common ancestor but not all of its descendants, which is a taxonomic concept rather than a feature describing shared derived traits.
In summary, only synapomorphies (option b) describe shared derived traits that delineate clades; the other options refer to different concepts or do not capture the idea of derived similarity.
