temperament, and this must early have given rise to a
corresponding division of labour. The general range of activities
that come under the head of exploit falls to the males as being
the stouter, more massive, better capable of a sudden and violent
strain, and more readily inclined to self assertion, active
emulation, and aggression. The difference in mass, in
physiological character, and in temperament may be slight among
the members of the primitive group; it appears, in fact, to be
relatively slight and inconsequential in some of the more archaic
communities with which we are acquainted -- as for instance the
tribes of the Andamans. But so soon as a differentiation of
function has well begun on the lines marked out by this
difference in physique and animus, the original difference
between the sexes will itself widen. A cumulative process of
selective adaptation to the new distribution of employments will
set in, especially if the habitat or the fauna with which the
group is in contact is such as to call for a considerable
exercise of the sturdier virtues. The habitual pursuit of large
game requires more of the manly qualities of massiveness,
agility, and ferocity, and it can therefore scarcely fail to
hasten and widen the differentiation of functions between the
sexes. And so soon as the group comes into hostile contact with
other groups, the divergence of function will take on the
developed form of a distinction between exploit and industry.

In such a predatory group of hunters it comes to be the
able-bodied men's office to fight and hunt. The women do what
other work there is to do -- other members who are unfit for
man's work being for this purpose classed with women. But the
men's hunting and fighting are both of the same general
