Family names will always end in _____ and Subfamily names will always end in____
shared by two organisms because they are
inherited from a common ancestor
similar anatomical structures that evolved independently to
accommodate a similar functional demand
how organisms might share a character that evolved independently in the two
independent evolution of similarity in closely-related organisms. Typically
there is similarity in the developmental pathway and genetic basis of similar traits.
independent evolution of similarity in distantly-related taxa. Typically,
there is dissimilarity in the developmental pathway and genetic basis of similar traits.
Homoplasy: Evolutionary reversal
the occurrence of a trait in a descendent that is identical to that of a distant ancestor, but different than of the immediate ancestor
Derived (normal, shared)
Primitive (normal, shared)
