As the etymology of the term suggests, these activities are devoted to the propagation, maintenance and protection of the race.

a. Reproduction.—The most fundamental one of the activities for the maintenance of the race is reproduction. Every living organism, whether plant or animal, possesses the power to reproduce its kind. Some plants produce spores and some produce seeds. Reference was made above to the production of the flower in plants. The flower represents the reproductive organ of the plant, and the real object of the flower is to produce the seed. Animals produce eggs from which the young develop, either through a process of incubation outside of a maternal body or an analogous process within the maternal body. In the latter case the young are brought forth as living organisms.

b. Support and Protection of Offspring.—Whether we consider the plant seed, or the animal egg or newborn—in any case the parental organism must provide for the support and protection of the offspring during those stages of development when it is unable to support and protect itself.

The plant deposits in or about the seed a supply of nourishment sufficient to support it during the germinating process and until it is able to gain its own support from the soil and air. Furthermore, the plant protects the seed by means of the various seed envelopes, against the cold and moisture of winter.

In a similar way the young animal is supplied by its parents with nourishment. The young bird is incubated within the egg where a supply of nourishment is provided sufficient to develop the bones, muscles, nervous system, blood, glands and covering—all developed to a point that makes the bird able to take from the mother during the early weeks after its release from the shell, such nourishment as the mother may provide. In the meantime it must be brooded and protected in the parental nest until it is able to provide for its own protection. Similarly the young mammal is developed within the body of the maternal organism to a point where it is able to perform the primitive functions of life. For weeks, months or even years, according to the class of the animal, it must be supported and protected by its parents. The human young receives milk from its mother's breast and protection in its mother's arms during its first year, after which it continues to receive nourishment, clothing and protection under the parental roof for a period varying from eighteen to twenty years, or even longer.

c. Support and Protection of Weaker Members of Society.—Young animals are supported and protected because they are unable to support and protect themselves. If they were not thus cared for the race would become extinct. Now, there are certain individuals, orphans for example, who have, through some accident, been deprived of their natural support and protection. If these weaker members of society, not yet able to support and protect themselves, were not provided for, they would perish and become thus lost to the race. From the time of primeval man to the present, these weaker individuals of society who have been deprived of their natural protectors, have been cared for by the stronger members of society and afforded such support and protection as they may need to make them independent. In a similar way the sick and defective members of society are cared for by the strong. Thus we see that the building and maintenance of orphanages, hospitals, asylums and "homes," are activities that belong clearly to the group of phyletic or altruistic activities.
