a shared ancestral charactistic used in cladistics is found a. in only the two most recent ancestors b. only among the members of the ingroup c. in both the outgroup and in group d. in two of the outgroups e. only in the most distant ancestor
Homework Answers
d. in two of the outgroups
In Cladistics, symplesiomorphy is the shared ancestral character state and two or more modern groups will share the ancestral trait in case of symplesiomorphy and it not useful for a person to assess the recent evolutionary relationship when the group is large.
