(n.) That series of changes under natural law which involves continuous progress from the homogeneous to the heterogeneous in structure, and from the single and simple to the diverse and manifold in quality or function.

It is also applied to explain the existence and growth of institutions, manners, language, civilization, and every product of human activity. The agencies and laws of the process are variously explained by different philosophrs.

Heredity
Definition:
(n.) Hereditary transmission of the physical and psychical qualities of parents to their offspring; the biological law by which living beings tend to repeat their characteristics in their descendants. See Pangenesis.
