CHAPTER IV

SEX SPECIALIZATION AND GROUP SURVIVAL

Adaptation and specialization; Reproduction a group not an individual
problem; Conflict between specialization and adaptation; Intelligence
makes for economy in adjustment to environment; Reproduction, not
production, the chief factor in the sex problem.

From the facts briefly stated in the preceding chapters it is quite
evident that the general superiority of man over woman or _vice versa_
cannot be proven by biology. Such an idea arises from a careless and
unscientific use of language. Superiority is a term which, when used to
express the rather exact ideas of biology, is employed in a carefully
limited and specific, not in a general, sense. That is, superiority,
even if an apparently general idea like survival value is referred to,
always implies a given, understood environment where such is not
specifically mentioned. Wolves, for example, might be found to possess
superior
