The Nature and Special Features of the Instinctive Social Bond of Primates

Man now forms social organizations that are larger than any previously developed by mammal. The forms of the societies that are still in existence are also very varied. We know that much of their size and variability is due to new features, to tool-making and -using, agriculture, new methods of movement and communication, etc.; and we can see that in the later and larger societies, more and more of the structure is dependent upon these new features and less is concerned with regulating the personal relations of people who meet one another in daily affairs.
