The second or predatory variant of the types is taken to be a survival of a more recent modification of the main ethnic types and their hybrids--of these types as they were modified, mainly by a selective adaptation, under the discipline of the predatory culture and the latter emulative culture of the quasi-peaceable stage, or the pecuniary culture proper.
Under the recognized laws of heredity there may be a survival from a more or less remote past phase.

In the ordinary, average, or normal case, if the type has varied, the traits of the type are transmitted approximately as they have stood in the recent past--which may be called the hereditary present.

For the purpose in hand this hereditary present is represented by the later predatory and the quasi-peaceable culture.
It is to the variant of human nature which is characteristic of this recent--hereditarily still existing--predatory or quasi-predatory culture that the modern civilized man tends to breed true in the common run of cases.

This proposition requires some qualification so far as concerns the descendants of the servile or repressed classes of barbarian times, but the qualification necessary is probably not so great as might at first thought appear.

Taking the population as a whole, this predatory, emulative variant does not seem to have attained a high degree of consistency or stability.
