Chapter Summary

The seventh edition has thirteen printed chapters and, according to the publisher, a fourteenth chapter on nematodes and sea urchins that now appears online as part of the e-book. The print volume runs to about 960 pages. The publisher's stated approach is to focus on underlying processes shared by diverse organisms, so that students see the "big picture", supported by custom-drawn artwork, learning objectives and summaries, interactive quizzes, medical boxes on developmental disease and experimental boxes that show "how we know what we know". The chapter descriptions below stay close to the published chapter titles and the publisher's account of what changed in this edition.

Chapter 1: History and basic concepts

The opening chapter sets out the history of the subject and the basic concepts on which the rest of the book draws.

Chapter 2: Development of the Drosophila body plan

The first of the model-organism chapters, on how the Drosophila body plan develops.

Chapters 3–4: Vertebrate development I: Establishing the body plan; Vertebrate development II: completing the body plan

Two chapters now cover vertebrate development. The publisher says they have been restructured and updated, especially for mouse development, so that major concepts and principles are explained with recent experimental evidence. The sixth edition, by comparison, divided vertebrate development into three chapters, organised by life cycles and techniques, by Xenopus and zebrafish, and by chick and mouse.

Chapter 5: Morphogenesis: change in form in the early embryo

The title indicates a focus on the changes in form that take place in the early embryo.

Chapter 6: Cell differentiation and stem cells

The title shows that the chapter deals with how cells differentiate and with stem cells. The publisher notes that this edition adds examples of CRISPR used to address problems such as sickle cell disease in Chapter 6.

Chapter 7: Embryonic stem cells, embryo models, and regenerative medicine

New in this edition. The publisher describes it as a response to a very active area of research, covering embryonic stem cells, embryo models and regenerative medicine.

Chapter 8: Germ cells, fertilization, and sex determination

The title shows that the chapter treats germ cells, fertilisation and sex determination.

Chapter 9: Organogenesis

The chapter's title marks it as the one on the formation of organs.

Chapter 10: Development of the nervous system

According to the publisher this chapter has been completely revised and updated, with more emphasis on neural tube patterning.

Chapter 11: Growth, post-embryonic development, and regeneration

By its title, the chapter follows development beyond the embryo, through growth, post-embryonic development and regeneration.

Chapter 12: Plant development

The only chapter on plants, extending the book's scope beyond animals.

Chapter 13: Evolution and development

The last printed chapter links development with evolution. The publisher gives the evolution of limbs from fins as one of the new examples where CRISPR is used.

Chapter 14 (online): Development of nematodes and sea urchins

Per the publisher, this chapter now appears online as part of the e-book. Print-only readers will not have it.

Key Concepts

Chapters 1–5: foundations and the early embryo

• Underlying principles: the processes that diverse organisms share, which the book uses as its organising idea.
• Body plan: the establishment of the main axes and regions in Drosophila and in vertebrates.
• Morphogenesis: the changes in form of the early embryo.

Chapters 6–9: cells, stem cells and organs

• Cell differentiation and stem cells: how cells acquire specialised states, with CRISPR examples such as sickle cell disease.
• Embryo models and regenerative medicine: the new Chapter 7 material.
• Germ cells and sex determination: the cells and processes of reproduction.
• Organogenesis: formation of organs.

Chapters 10–14: nervous system, growth, plants and evolution

• Neural tube patterning: emphasised in the revised nervous system chapter.
• Regeneration: restoration of lost tissue after the embryonic period.
• Evolution of development: how changes in development relate to evolutionary change, with the fin-to-limb example.

Critical Analysis

Strengths

• A principles-first organisation. The publisher organises the book around shared underlying processes rather than a catalogue of organisms, and the chapters sequence from basic concepts to model organisms, stem cells, organs and evolution.
• Learning support. The publisher lists learning objectives, summaries, interactive quizzes (in the e-book), medical boxes on developmental disease and experimental boxes showing how knowledge was obtained.
• Updated for current research. A new chapter on embryonic stem cells and embryo models, a revised nervous system chapter and single-cell RNA sequencing examples in Chapters 3, 6, 7, 10, 11 and 12 show the edition tracking recent work.
• Wide coverage. The book includes plant development and an evolution chapter, not just the animal models.

Limitations

• Heavy. At about 960 pages, the book is more than a typical single-term course can cover.
• One chapter is online only. Nematodes and sea urchins, standard model systems, are available only with the e-book.
• Biology prerequisites. A grounding in cell and molecular biology and genetics helps, since the molecular explanations are central to the book's approach.

Where It Fits in the Course

This is the main full-length developmental biology textbook in a list that also holds shorter and more specialised books. Wolpert's own Developmental Biology: A Very Short Introduction and Davies's Life Unfolding are brief, accessible accounts for general readers. Slack's Essential Developmental Biology is a compact textbook that uses a small set of model organisms to establish general principles, and Barresi and Gilbert's Developmental Biology combines classical embryology with molecular mechanisms across the major model organisms. Carroll, Grenier and Weatherbee's From DNA to Diversity is a concise evolutionary developmental biology text, a useful companion to the final chapter here.

Tickle and colleagues sit in the middle of the list: fuller than Slack's compact text, with the principles-first framing as their distinctive feature. Readers who want a second view of the same ground can compare it with Barresi and Gilbert.

How to Use This Book

The book is aimed at undergraduates in biology, medicine and veterinary science, and suits second- or third-year students with cell and molecular biology and basic genetics. It also works as a reference for graduate students entering the field.

A practical plan:

• Core: Chapters 1–4 for the concepts and the Drosophila and vertebrate body plans, then Chapter 6 for differentiation and stem cells.
• Choose by course: Chapter 5 on morphogenesis, Chapter 9 on organogenesis and Chapter 10 on the nervous system are common selections. Chapter 7 is the one for stem cell and regenerative medicine courses.
• Optional: Chapters 11–13 on growth and regeneration, plants, and evolution; the online nematode and sea urchin chapter if you have the e-book.
• Use the learning features. Read the learning objectives and chapter summaries first, and use the medical and experimental boxes to connect the principles to disease and to the original experiments.
