Part 9/9:
Animal development is an exquisitely orchestrated sequence of events starting from fertilization, progressing through cleavage, gastrulation, and organogenesis. This process involves precise cellular movements, differentiation, and signaling pathways that collectively give rise to complex tissues and organs. Understanding these foundational processes offers insight into the fundamental biology that underpins how multicellular organisms develop, regenerate, and maintain their intricate structures.
This overview highlights the core stages and mechanisms of animal development, emphasizing the importance of early embryogenesis, tissue differentiation, and the integrative signals that guide the formation of a fully functioning organism.
