Written primarily for 16-19-year-old students, this primer introduces the subject of developmental biology through a wide range of organisms, offering insights into the fundamental principles that shape life's diverse and extraordinary forms. It covers all the essential topics, including cell biology, cell signalling, cell specialization, genomic control of development, evidence for evolution, and cell ageing and death. The author guides students carefully and gradually through the concise contents, providing a robust basis for understanding the molecular and morphological events that occur during embryo development, but that are also important in adult homeostasis, regeneration, and disease. Students will delve into the secrets of stem cells, the marvels of regeneration, and the paradox of how a broadly conserved genome can support the biodiversity we see throughout the natural world. Engaging case studies and 'scientific approach' boxes challenge the reader to think critically and practice scientific inquiry, while open-ended discussion questions draw on students' creativity and curiosity. Animal Developmental Biology is the ideal companion for students transitioning from biology at school to university. It offers a first taste of biology beyond the classroom and illustrates the relevance of concepts encountered at school to current research.
