Refer to the figure below. The figure shows early steps in the embryonic development of a simple vertebrate animal.Each figure represents a cross-sectional view of a developing embryo.The blastula can be described as a ball of cells.These cells formed from a fertilized egg that underwent several rounds of cell division.The blastula then undergoes invagination to form the gastrula as shown in the diagram.During invagination, some cells are pushed up into the center of the ball, creating a cell-lined pocket on the inside of the gastrula.This pocket later becomes the digestive tract of the developing animal.All vertebrate animals follow this pattern of development.Analyze the diagram to explain why the process of gastrulation provides the opportunity for the evolution of cell specialization and multicellularity in animals.
