Features: This book is compiled by Cheng Hong and Chen Maosheng from the School of Life Sciences, Peking University. Based on the construction of animal morphology and the evolutionary path from single-celled to multi-celled organisms, from simple to complex, from lower to higher animals, from invertebrates to vertebrates, and from aquatic to terrestrial environments, a total of 21 animal science experiments are arranged. Each experiment includes principles, methods, and steps. This book is suitable for undergraduate students of life sciences and related majors in higher education institutions, as well as for reference by relevant teachers. The book guides students to understand animals from the vast knowledge base of zoology using two lines of thought: one is the construction of animal morphology, from cells, tissues, organs to systems, and then to the whole animal; the other is the evolutionary process of animals from single-celled to multi-celled, from simple to complex, from lower to higher, from invertebrates to vertebrates, and from aquatic to terrestrial environments. To help readers clearly see these two lines of thought in experiments, the book is divided into three parts: (1) animal cytology, histology, and development; (2) protozoa and invertebrates; (3) chordates. The book first introduces basic knowledge of animal experiments, such as drawing requirements, dissection tools and their use, precautions for using microscopes, dissection sections and orientations, and general dissection methods. It then arranges 21 experiments. The first seven experiments are Part I, mainly reflecting the construction of animal morphology; the second part, experiments 8–15, includes observations and dissections of representative animals of protozoa and important groups in the evolutionary line of invertebrates, such as sponges, coelenterates, flatworms, nematodes, annelids, arthropods, and echinoderms. The third part, experiments 16–21, focuses on the dissection structures and main taxonomic groups of representative animals on the evolutionary line of chordates, such as amphioxus, bony fish, toad, skink, chicken, and rabbit. Each experiment introduces the purpose, methods, specific steps and sequence, and precautions, followed by assignments and discussion questions. The book has good theoretical, sequential, and instructional qualities, is illustrated with diagrams, and allows students to learn and operate independently. In specific teaching, instructors can choose, segment, and combine experiments in the book based on their teaching content, time, and conditions. The cytology and histology part of the book is written by Chen Maosheng, while the rest is written by Cheng Hong. Mr. Li Shaowen provided the "Simple Key to the Orders of Adult Insects." The entire book was compiled by Cheng Hong.
