(Cf. the phenomenon
of the «runners» at first connected with the mother plant and then separated from it; the fluid transition between various plants and
animals which appear to be one; the germ - cell inside and outside the parent organism, etc.)
Living forms which present what are apparently very great
differences in space and time can ontologically have the same morphological principle, so that
enormous differences of external form can derive from the material substratum and chance patterns
of circumstance without change
of substantial form (caterpillar - chrysalis butterfly).
