Most minority groups can also be identified as ethnic groups, but ethnic groups require a real or fictive kinship as well as cultural indicia. A real kinship is when all of the members of an ethnic group are actually related (almost never true unless incest is common) and fictive kinship is when all of the members of an ethnic group believe that they descend from common ancestors, even though many of the members may not actually descend from these ancestors (even assuming that they are historical persons). Cultural indicia refers to a group possessing unique or distinctive: foods, languages, social behaviors, taboos, religions, social hierarchies, home construction, life-cycle events, etc. An ethnicity need not be unique in all of the cultural indicia, but unique enough to differentiate it from its neighbors.
they were not really divided into two groups but if you want two gruops how about male and female.

There are two familes. Strigidae, typical owls, and Tytonidae, barn owls.
Cro-Magnon groups likely ranged in size from 20 to 30 individuals. These groups would have consisted of extended family members and would have worked together to hunt, gather food, and care for one another. Cooperation within the group was crucial for their survival in the harsh prehistoric environment.
