Recent technological and intellectual advances that have changed thinking about five questions about how have bacteria facilitated the origin and evolution of animals; how do animals and bacteria affect each other’s genomes; how does normal animal development depend on bacterial partners; and how is homeostasis maintained between animals and their symbionts are highlighted.
Resynthesizing evolutionary and developmental biology.
A new and more robust evolutionary synthesis is emerging that attempts to explain macroevolution as well as microevolutionary events, and the morphogenetic field is seen as a major unit of ontogeny whose changes bring about changes in evolution.
A Symbiotic View of Life: We Have Never Been Individuals
Recognizing the “holobiont”—the multicellular eukaryote plus its colonies of persistent symbionts—as a critically important unit of anatomy, development, physiology, immunology, and evolution opens up new investigative avenues and conceptually challenges the ways in which the biological subdisciplines have heretofore characterized living entities.

Bioethics and the New Embryology: Springboards for Debate
This chapter discusses the ethics of animal use in research in research, as well as arguments for and against sex selection, and new perspectives on old issues.
Embracing complexity: Organicism for the 21st century
This essay attempts to define organicism, provide a brief history of its importance to experimental embryology, outline some sociologically based reasons for its decline, and document its value in contemporary developmental biology.
Morphogenesis of the turtle shell: the development of a novel structure in tetrapod evolution
An anatomical investigations into plastron and carapace formation in the red‐eared slider, Trachemys scripta, and the snapping turtle, Chelydra serpentina suggest that the rib is organizing dermal ossification by secreting paracrine factors.
