In process of time, so Mr Atkinson suggests, with the lengthening
childhood conditioned by the progress of the race, maternal love of a
more enduring kind developed, than is found among the non-human species
of the present day. This led eventually to the presence of a young male,
perhaps the youngest born of a given mother, being permitted to remain,
on conditions, in the herd after he had attained maturity. The original
lord and master of the herd retained, Mr Atkinson supposes, his full
sovereignty over the females born in the herd as well as over those whom
his prowess had perhaps added to it from time to time. The young male on
the other hand was not condemned to a life of celibacy as a condition of
his non-enforcement of the traditional decree of banishment. He was
permitted to find a mate, but she must be a mate not born in the herd,
nor one of the harem of his sire; he had, if he wished to wed, to
capture a spouse for himself from another herd. For the detailed working
out of this ingenious theory we must refer our readers to Mr Atkinson's
work, _Primal Law_. Here it suffices to state the primal law which
resulted from the process sketched above. This primal law was "thou
shalt not marry within the group." This law, at first enforced by the
superior strength of the sire, came in the process of time to be a
traditional rule of conduct, almost an instinct. And with this we reach
the theory put forward in _Social Origins_ by Mr Andrew Lang, according
to which local groups received animal names, perhaps from their
neighbours. These local groups being exogamous for the reason just
given, and the group name being eventually[108] given, not only to the
actual members of the group, but also to the women, captured or
otherwise, who became the mates of the men of the adjoining groups, it
necessarily resulted that the men of a group, so long as the mother's
group name did not descend to her children, were of one name, while
their wives were of another, or more probably of many other names. The
group became definitely heterogeneous when the maternal group name
descended to the children born in the alien group, and in process of
time these maternal group names became totem names.

Meanwhile the original group names had been retained and applied, along
with the totem or quasi-totem names, to the members of the group; the
name being probably, in the first place, that of the group in which they
were born, but
