The Key to Human Nature could be discovered by knowing the Cell Structure and Functions. If hereditary behavior is operated by information present in genes, it must be noted that the genes have no independent existence of their own. The nucleus and the genes perform their cellular functions deriving energy from the cytoplasm or protoplasm of the cell. The biological properties, characteristics, and the biological nature of the living substance or protoplasm could account for the instinctive behavior pattern of compassion.
