The Cell in Development and Inheritance, by Edmund Beecher Wilson, provided a textbook introduction to cell biology for generations of biologists in the twentieth century. In his book, Wilson integrated information about development, inheritance, chromosomes, organelles, and the structure and functions of cells. First published in 1896, the book started with 371 pages, grew to 483 pages in the second edition that appeared in 1900, and expanded to 1,231 pages by the third and final edition in 1925. Wilson dedicated the book to the cell biologist Theodor Boveri, whose work established the roles of chromosomes in cell division. With its explanations and many illustrations and diagrams, The Cell in Development and Inheritance enabled embryologists to better understand development in terms of cell structure and function.

In “The Social and Psychological Impact of Endometriosis on Women’s Lives: A Critical Narrative Review,” hereafter “Social and Psychological Impact of Endometriosis,” authors Lorraine Culley, Caroline Law, Nicky Hudson, Elaine Denny, Helene Mitchell, Miriam Baumgarten, and Nicholas Raine-Fenning review the extent at which endometriosis results in a negative quality of life for affected women. Endometriosis is a condition characterized by the growth of cells similar to that of the endometrium, or the tissue that lines the uterus, outside of the uterus, and can cause heavy menstrual periods, pain, and infertility. Such symptoms can impact how women balance romantic or sexual relationships, due to the fact that endometriosis can cause chronic pelvic pain and pain during sexual intercourse. The authors found that women living with endometriosis are more likely to experience depression or anxiety, and conclude that the lack of both overall academic research and factual information given to women at diagnosis results in negative effects on their psychological wellbeing.

Leo Kanner published Autistic Disturbances of Affective Contact in 1943 in the journal Nervous Child. This article described the cases of eleven children with autism. Kanner described the behavior and upbringing of each child, aged two to eight, as well as the educational backgrounds of the children's. Though Eugen Bleuler, a professor of psychiatric at the University of Z rich and director of the Burgh lzli Asylum in Z rich in Z rich, Switzerland from 1898 to 1927, was first to use the term autism to describe of a symptom of schizophrenia, scientists cite Kanner's article as the first description of autism as a unique disease concept distinct from schizophrenia. One of the most cited articles about autism in the twentieth century, this article was the first to demarcate Kanner syndrome, which later called childhood autism. Researchers, including Kanner, eventually treated early infantile autism as a disorder resulting from abnormal development of the autistic children's brains.

Rachel L. Carson studied biology at Johns Hopkins University in Maryland and graduated in 1933 with an MA upon the completion of her thesis, The Development of the Pronephros during the Embryonic and Early Larval Life of the Catfish (Ictalurus punctatus). The research that Carson conducted for this thesis project grounded many of the claims and observations she presented in her 1962 book, Silent Spring. This book focused on the environmental dangers of using pesticides against insects and plants deemed invasive, and it received attention from the US government, to such an extent that Carson testified before US congress in Washington D.C., and US President John F. Kennedy appointed a commission to validate her claims.

In 1987 Rebecca Louise Cann, Mark Stoneking, and Allan Charles Wilson published Mitochondrial DNA and Human Evolution in the journal Nature. The authors compared mitochondrial DNA from different human populations worldwide, and from those comparisons they argued that all human populations had a common ancestor in Africa around 200,000 years ago. Mitochondria DNA (mtDNA) is a small circular genome found in the subcellular organelles, called mitochondria. Mitochondria are organelles found outside of the nucleus in the watery part of the cell, called cytoplasm, of most complex cells (eukaryotes). Cann, Stoneking and Wilson collected mtDNA from 147 individuals from five different human geographical populations. Cann, Stoneking, and Wilson used mtDNA sequences to study the genetic differences and migration patterns of the human population through female inheritance. Mammals inherit mitochondria and mtDNA from their mothers through the egg cell (oocyte), and mitochondria are responsible for several maternally inherited diseases.

To educate its citizens about research into chimeras made from human and non-human animal cells, the United Kingdom's Human Fertilisation Embryology Authority published the consultation piece Hybrids and Chimeras: A Consultation on the Ethical and Social Implications of Creating Human/Animal Embryos in Research, in 2007. The document provided scientific and legal background, described ethical and social issues associated with research using part-human part-animal embryos, supplied a questionnaire for citizens to return to the HFEA with their opinions, and offered a list of resources for further reading to stimulate public debate. The strategy of surveying the public provided a template for developing further policy in the United Kingdom and other countries, as well as for educating citizens on embryological research.

Ontogeny and Phylogeny is a book published in 1977, in which the author Stephen J. Gould, who worked in the US, tells a history of the theory of recapitulation. A theory of recapitulation aims to explain the relationship between the embryonic development of an organism (ontogeny) and the evolution of that organism's species (phylogeny). Although there are several variations of recapitulationist theories, most claim that during embryonic development an organism repeats the adult stages of organisms from those species in it's evolutionary history. Gould suggests that, although fewer biologists invoked recapitulation theories in the twentieth century compared to those in the nineteenth and eighteenth centuries, some aspects of the theory of recapitulation remained important for understanding evolution. Gould notes that the concepts of acceleration and retardation during development entail that changes in developmental timing (heterochrony) can result in a trait appearing either earlier or later than normal in developmental processes. Gould argues that these changes in the timing of embryonic development provide the raw materials or novelties upon which natural selection acts.

The Origin and Behavior of Mutable Loci in Maize, by Barbara McClintock, was published in 1950 in the Proceedings of the National Academy of Sciences of the United States of America. McClintock worked at the Cold Spring Harbor Laboratory in Laurel Hollow, New York, at the time of the publication, and describes her discovery of transposable elements in the genome of corn (Zea mays). Transposable elements, sometimes called transposons or jumping genes, are pieces of the chromosome capable of physically changing positions along the chromosome. The Origin and Behavior explains the mechanics of development that occur in maize kernels, which are plant embryos.

The Spandrels of San Marco and the Panglossian Paradigm: A Critique of the Adaptationist Programme, hereafter called The Spandrels, is an article written by Stephen J. Gould and Richard C. Lewontin published in the Proceedings of the Royal Society of London in 1979. The paper emphasizes issues with what the two authors call adaptationism or the adaptationist programme as a framework to explain how species and traits evolved. The paper is one in a series of works in which Gould emphasized the role of development in evolutionary theories. The article suggests that constraints on how organisms can develop and constraints on how species can evolve from others play a central role in explaining the how species and traits evolve. The authors note that organisms from different species develop as embryos through stages similar across species, genera, and higher classes. Gould and Lewontin hypothesize that those stages constrained the possible pathways of evolution and has therefore guided the history of life. Throughout the paper, the authors rely on analogy of some parts of organisms to architectural structures called spandrels, marked in this image as 'a'."

In 1972, David Whittingham, Stanley Leibo, and Peter Mazur published the paper, “Survival of Mouse Embryos Frozen to -196 ° and -269 °C,” hereafter, “Survival of Mouse Embryos,” in the journal Science. The study marked one of the first times that researchers had successfully cryopreserved, or preserved and stored by freezing, a mammalian embryo and later transferred that embryo to a live mouse who gave birth to viable offspring. Previously, scientists had only been successful cryopreserving single cells, like red blood cells. Mammalian embryos, on the other hand, were more difficult to cryopreserve because they are more complex and therefore more easily weakened or destroyed by the formation of ice within its cells. Whittingham, Leibo, and Mazur’s work provided a successful model for mammalian embryo cryopreservation, a technology that later expanded to cryopreserve more complex embryos, such as human embryos.
