 Another is autonomous morphogenesis, which points out that a living being's structure results from interactions within the being as opposed to the external forces that shape artificial artifacts.Monod offers a single exception to this last criterion in the form of a crystal and, at this point, he states that the internal forces that determine structure within living beings are "of the same nature as the microscopic interactions responsible for crystalline morphologies" (Monod, 11), a theme that he promises to develop in later chapters.The last general property Monod offers up as distinguishing living organisms is reproductive invariance which is the ability of a living being to reproduce and transmit the information corresponding to their own highly ordered structure.
