An outgroup is a species or group of species from an evolutionary lineage that is known to have diverged before the lineage that contains the group of species being studied.
An outgroup is a species or group of species that diverged earlier than the group being studied, serving as a reference point for evolutionary comparisons.
| Front | outgroup |
|---|---|
| Back | A species or group of species from an evolutionary lineage that is known to have diverged before the lineage that contains the group of species being studied. [This] is selected so that its members are closely related to the group of species being studied, but not as closely related as any study-group members are to each other. |
