Theory of Morphogenesis Considered
Dr. J.W.S. Pringle, F.R.S., of the Department of Zoology, Cambridge, in his paper on “The Origin of Life” which appeared in the Symposia of the Society for Experimental Biology, Number VII, Evolution, 1953, has, under the heading, “The Appearance of Heterogeneity,” dealt with Alan’s theory of morphogenesis and his mathematical approach to the subject. The relative passage runs;
Turing (1952) has demonstrated by mathematical methods that certain types of dynamic system which are initially homogeneous undergo a progressive change which leads to the appearance of spatial heterogeneity. The essential minimum for this behaviour to occur appears to be the presence of two substances, which he calls morphogens, ...
