DP Class DP2

DP2, a subclass of Developmental Pattern (DP) Class II, describes organisms with embryos that develop from a relatively simple, unsegmented structure called a blastula, which then undergoes specific cell movements and organization. This pattern is characteristic of many vertebrates, including mammals, birds, and reptiles. In DP2, early development features a hollow ball of cells that later differentiates into complex tissues and organs. The process involves processes like gastrulation, where the embryo's layers form, setting the foundation for specialized body structures. Overall, DP2 reflects a conserved developmental strategy sharing common features across diverse vertebrate species.
