WebGastrulation does not always proceed exactly as described above. In the course of evolution, certain animal groups have modified this critical stage of embryonic development, and these modifications have undoubtedly contributed to the successful continuation of species. In the primitive fishlike chordate amphioxus, for example, the invaginating … Gastrulation is highly variable across the animal kingdom but has underlying similarities. Gastrulation has been studied in many animals, but some models have been used for longer than others. Furthermore, it is easier to study development in animals that develop outside the mother. Model organisms whose gastrulation is understood in the greatest detail include the mollusc, sea urchin, frog, and chicken.

WebAug 1, 2015 · Teleost gastrulation is a highly derived process that appears to have little in common with the ancestral version. However, teleost gastrulation may have evolved as a result of two specific developmental changes: loss of bottle cells in the surface layer, and changes in the yolk.
