Dissertation: Lessons from Embryos: Haeckel’s Embryo Drawings, Evolution, and Secondary Biology Textbooks

Haeckel believed that the development of an embryo revealed the adult stages of the organism’s ancestors. Haeckel represented this idea with drawings of vertebrate embryos at similar developmental stages. This is Haeckel’s embryo grid, the most common of all illustrations in biology textbooks. Yet, Haeckel’s embryo grids are much more complex than any textbook explanation. I examined 240 high school biology textbooks, from 1907 to 2010, for embryo grids.

Thesis: From Fertilization to Birth: Representing Development in High School Biology Textbooks

Biology textbooks are everybody's business. In accepting the view that texts are created with specific social goals in mind, I examined 127 twentieth-century high school biology textbooks for representations of animal development. Paragraphs and visual representations were coded and placed in one of four scientific literacy categories, including descriptive, investigative, nature of science, and HETS, or human embryos, technology, and society. I then interpreted how embryos and fetuses have been socially constructed for students.

Essay: Review of Icons of Life: A Cultural History of Human Embryos

To Lynn M. Morgan, the Mary E. Woolley Professor of Anthropology at Mt. Holyoke College, nothing says life more than a dead embryo. In her easily readable book, Icons of Life: A Cultural History of Human Embryos, Morgan brings together cultural phenomena, ethics, and embryology to show that even dead embryos and fetuses have their own stories to tell. As an anthropologist, Morgan is interested in many things, including the science of embryology and its history. But she also wants to know how culture influences our views on embryos and the material practices that accompany their study.
