regulative development

regulative development

[reg′yəlā′tiv]
Etymology: L, regula, rule
a type of embryonic development in which the fertilized ovum undergoes indeterminate cleavage, producing blastomeres that have similar developmental potencies and are each capable of giving rise to a single embryo. Determination of the particular organs and parts of the embryo occurs during later stages of development and is influenced by inductors and intercellular interaction. Damage or destruction of various cells during the early stages of development results in readjustments and substitutions so that a normal organism is formed. Compare mosaic development.

Regulative development differs from the mosaic development of invertebrates, whose cells' characteristics are defined more by the nonnuclear factors of a cell (e.
Whichever way one goes, one cannot deny regulative development and the lack of individuality that accompanies it and therefore one cannot claim as Johnson does that it is "an organism like us,"(3) since we cannot do this.
The fertilized egg contains the information necessary to replicate another human being, but until the process of regulative development is over and the cells become restricted, what we have is human nature in the process of becoming individuated.
