We studied individual pathways of gastrulation in two related amphibian species making an emphasis on the developmental dynamics of normal variation in the geometry of gastrulation movements. Analyzing the variation dynamics, we show that the linear succession of developmental stages is a secondary phenomenon disguising self-oscillations that lie at the heart of the dorsal blastopore lip morphogenesis. Characteristic features of the equations derived to describe the oscillations are, first… CONTINUE READING
