Unfortunately, the amount of precise work of this kind has been very small.
From the biological standpoint the probability of gregariousness being a primitive and fundamental quality in man seems to be considerable. As already pointed out, like the other great enlargement of the biological unit, but in a much more easily recognizable degree, it would appear to have the effect of enlarging the advantages of variation. Varieties not immediately favourable, varieties departing widely from the standard, varieties even unfavourable to the individual may be supposed to be given by it a chance of survival. Now the course of the development of man seems to present many features incompatible with its having proceeded amongst isolated individuals exposed to the unmodified action of natural selection.
