A superficial view of the group we have examined might, from its general resemblance in custom to others among actual lower types of man, lead to a hasty conception of perfect identity, from a social point of view, in nearly all other respects. We see that exogamy, hostile capture, group marriage,[1] and obedience to certain accepted rules of avoidance, are common to both, to the hypothetical semi-bestial and to the actual savage groups. The impression, however, would be very erroneous. In the former, the hypothetical archaic stage, still lurked as a festering canker, an archaic element in marital prerogative, which marks it as of an epoch in the life-history of our race when the brute still triumphed over the man, an epoch far removed from our own. It possessed a feature in connubial relations as between certain group members which placed a profound gulf between it and any existing form of these days--a trait which, whilst it endured, would tend to render all further social progress difficult, if not impossible. It barred the road to that next great gradation in sociological evolution which is implied in the friendly conjunction of groups in a tribe. The latter stage was a vast upward step, but still it was only one round in the ladder of ascent to man, and indeed derived its chief importance from this fact as such. The tribe was the real goal; there, only, could be found the vital quality of social stability to be conferred by peaceful _connubium_ between united groups as opposed to hostile capture between isolated families. Each group must come to be in itself complete, and yet each must form the necessary complementary parts of the actual _Tribe_ common to all lower races, with its typical divisional inter-marriageable group classes [‘phratries’]. The fatal bar to a higher platform was a heritage from the anthropoid ancestor, and, as such, eminently characteristic of an animal stage.
