The First Successful Cloning of a Gaur (2000), by Advanced Cell Technology
The first successful cloning of a gaur in 2000 by Advanced Cell Technology involved the cells of two animals: an egg cell from a domestic cow and a skin cell from a gaur. The researchers extracted the egg cell from the ovary of the domestic cow and the skin cell from the skin of the gaur. First, the researchers performed nuclear transplantation on the egg cell of the cow, during which they removed the nucleus of the egg cell. The mitochondria of the egg cell remained intact inside the cell.

Kangaroo Mother Care
Physician researchers Edgar Rey Sanabria and Héctor Martínez-Gómez developed the Kangaroo Mother Program in Bogotá, Colombia, in 1979, as an alternative to conventional incubator treatment for low birth weight infants. As of 2018, low birth weight and its associated complications are the leading causes of infant death, especially in developing and underdeveloped countries where access to technology and skilled healthcare providers is limited. Kangaroo Mother Care is a simple and low cost method for treating low birth weight infants.
Charles Manning Child designed an experimental test, the susceptibility assay, to measure the effects of different toxins on developmental processes. The susceptibility assay measured an organism s vulnerability to death when it was submerged in a noxious solution. The assay involved immersing an organism in a solution that contained a depressant or inhibitory substance, such as alcohol, and then measuring the responses of the organism. Child interpreted these measurements as revealing information about the relative levels of metabolic activity within the organism.
Aristotle (384-322 BCE)
Aristotle studied developing organisms, among other things, in ancient Greece, and his writings shaped Western philosophy and natural science for greater than two thousand years. He spent much of his life in Greece and studied with Plato at Plato's Academy in Athens, where he later established his own school called the Lyceum. Aristotle wrote greater than 150 treatises on subjects ranging from aesthetics, politics, ethics, and natural philosophy, which include physics and biology. Less than fifty of Aristotle's treatises persisted into the twenty-first century.
The Sex Side of Life (1919) by Mary Ware Dennett
Mary Ware Dennett, an activist in the US for birth control and sex education in the early twentieth century, wrote an educational pamphlet in 1915 called “The Sex Side of Life, and it was published in 1919. The pamphlet defined the functions of the sex organs, emphasized the role of love and pleasure in sex, and described other sexual processes of the body not usually discussed openly.
Beadle and Ephrussi's Transplantation Technique for Drosophila
Boris Ephrussi and George Wells Beadle developed a transplantation technique on flies, Drosophila melanogaster, which they described in their 1936 article A Technique of Transplantation for Drosophila. The technique of injecting a tissue from one fly larva into another fly larva, using a micropipette, to grow that tissue in the second larvae, was a means for investigating development of Drosophila. Through this technique, Beadle and Ephrussi studied the role of genes in embryological processes.
Gunther von Hagens (1945- )
Gunther von Hagens invented a plastination technique and created Body Worlds, a traveling exhibit that has made anatomy part of the public domain. Von Hagens invented the plastination technique in 1977 while working at Heidelberg University in Heidelberg, Germany. Von Hagen's plastination technique preserves real bodies and tissues by the removal of the fluid and replacement with resin. Body Worlds features three-dimensional, plastinated human bodies.

Stanley Paul Leibo (1937–2014)
Stanley Paul Leibo studied the cryopreservation of embryos in the US in the twentieth century. Cryopreservation is a method of preserving biological material through freezing. Early in his career, Leibo collaborated with other scientists to study why cells were oftentimes injured during freezing. Later, Leibo and his team accomplished one of the first successful births using previously-frozen mammalian embryos.

The term morphogenesis generally refers to the processes by which order is created in the developing organism. This order is achieved as differentiated cells carefully organize into tissues, organs, organ systems, and ultimately the organism as a whole. Questions centered on morphogenesis have aimed to uncover the mechanisms responsible for this organization, and developmental biology textbooks have identified morphogenesis as one of the main challenges in the field. The concept of morphogenesis is intertwined with those of differentiation, growth, and reproduction.

Biological Lectures Delivered at the Marine Biological Laboratory in Woods Hole
The Marine Biological Laboratory in Woods Hole, Massachusetts, began in 1888 with one building housing researchers upstairs and students in a shared lab and lecture space downstairs. For the first two years, instruction took the form of general lectures covering a range of topics in zoology. In addition, the trustees offered some public lectures in Boston to raise funds for the lab.

Thesis: The Human Genome Project and ELSI: The Imperative of Technology and Reduction of the Public Ethics Debate
Portrayed as the Manhattan Project of the late 20th century, the Human Genome Project, or HGP, not only undertook the science of sequencing the human genome but also the ethics of it. For this thesis I ask how the HGP did this; what was the range of possibilities of goods and evils imagined by the HGP; and what, if anything, was left out.

Menstrual Hygiene Management in Low-Income Countries
Menstrual hygiene management, or MHM, is a concept that concerns girls' and women’s access to the appropriate information and resources to manage menstruation. In December 2012, the Joint Monitoring Program, or JMP, was one of the first organizations to define MHM as a global development goal. Since then, other organizations like WaterAid and the United Nations have expanded MHM’s definition to include menstrual education that is biologically accurate and free of taboo and stigma.
Gunther von Hagens' Plastination Technique
Plastination is a technique for preserving tissues, organs, and whole bodies for medical purposes and public display. Gunther von Hagens invented a form of the method in 1977 at Heidelberg University in Heidelberg, Germany after observing medical students struggle working with cadavers that quickly decomposed. Von Hagens' body models, referred to as plastinates, have since become widely used educational tools not only for those studying anatomy and medicine, but also for the general public.
Leo Loeb (1869-1959)
Leo Loeb developed an experimental approach to studying cancer and pioneered techniques for tissue culture and in vitro tissue transplantation which impacted early-to-mid twentieth century experimental embryology. Loeb received his medical degree from the University of Zurich in 1897. As part of his doctorate, he completed a thesis on the outcomes of tissue transplantation in guinea pigs. Loeb's thesis inspired a life-long interest in tissue transplantation.
Hans Asperger (1906-1980)
Hans Asperger studied mental abnormalities in children in
Vienna, Austria, in the early twentieth century. Asperger was one of
the early researchers who studied the syndrome that was later named
after him, Asperger's Syndrome. Asperger described the syndrome in
his 1944 publication Die Autistischen Psychopathen im
Kindesalter (Autistic Psychopathy in Childhood). At that time,
the syndrome was called autistic psychopathy, and Asperger noted
that characteristics of the syndrome included lack of sympathy,
Evelyn Lorraine Rothman (1932–2007)
Evelyn Lorraine Rothman advocated for women’s reproductive rights and invented at-home kits for women’s health concerns in the late twentieth century in Los Angeles, California. Rothman provided women in the Los Angeles area with the means to perform self-examinations, pregnancy tests, and abortions on their own without assistance from a medical professional. Along with Carol Downer, Rothman cofounded the Federation of Feminist Health Centers in Los Angeles, California, and spent her career educating women on reproductive health.
Kass v. Kass (1998)
In Maureen Kass v. Steven Kass (1998), the Court of Appeals of New York in Albany, New York, ruled that the state should generally consider IVF consent forms signed by participants in an in vitro fertilization (IVF) program valid, binding, and enforceable in the event of a dispute. The court indicated that decisions regarding the handling of cryopreserved pre-zygotes, often called preembryos, contained within these consent forms should be upheld.
Frederik Ruysch (1638-1731)
Frederik Ruysch made anatomical drawings and collected and preserved human specimens, many of which were infants and fetuses, in the Netherlands during the seventeenth and eighteenth centuries. Ruysch had many interests, including anatomy, botany, and medicine, and he discovered structures of the lymphatic system and of the eye. His collection of preserved human specimens were used as educational tools for his students and for other physicians, and they were displayed in a museum of his own making that was open to the public.
A. Z. v. B. Z. (2000)
In A.Z. v. B.Z. (2000), the Supreme Judicial Court of Massachusetts in Boston, Massachusetts, affirmed a lower courtÕs decision, ruling that contracts that require a party to become a parent against his or her will are unenforceable and contrary to public policy. The case centered around A.Z. and B.Z., a divorced couple who had previously used in vitro fertilization (IVF) to start a family together during their marriage and had several preembryos cryopreserved as part of the process.
A germ layer is a group of cells in an embryo that interact with each other as the embryo develops and contribute to the formation of all organs and tissues. All animals, except perhaps sponges, form two or three germ layers. The germ layers develop early in embryonic life, through the process of gastrulation. During gastrulation, a hollow cluster of cells called a blastula reorganizes into two primary germ layers: an inner layer, called endoderm, and an outer layer, called ectoderm.
“A New Vision for Advancing Our Movement for Reproductive Health, Reproductive Rights, and Reproductive Justice” (2005), by Asian Communities for Reproductive Justice (ACRJ)
In 2005, the organization Asian Communities for Reproductive Justice, or ACRJ, published “A New Vision for Advancing Our Movement for Reproductive Health, Reproductive Rights, and Reproductive Justice,” hereafter “A New Vision,” in which the authors explain how reproductive justice is hindered by societal oppressions against women of color. ACRJ, known as Forward Together since 2012, was a founding member of SisterSong Women of Color Reproductive Justice Collective, a collective of organizations founded by people of color that work to advance the reproductive justice movement.

Biological Sex and Gender in the United States
In the United States, most people are assigned both a biological sex and gender at birth based on their chromosomes and reproductive organs. However, there is an important distinction between biological sex and gender. Biological sex, such as male, female, or intersex, commonly refers to physical characteristics. Gender refers to the socially constructed roles, behaviors, and actions people take on, usually in relation to expectations of masculinity or femininity. As of 2022, there is disagreement over the relation between sex and gender.

Americans with Disabilities Act (1990)
In 1990, the United States Congress passed the Americans with Disabilities Act, or the ADA, which prohibits discrimination against people with disabilities by employers, governments, or public accommodations. Following gains made during the civil rights movements of the 1900s, people with disabilities sought similar anti-discrimination legislation. The ADA was the culmination of decades of protest and advocacy from the disability rights movement. After the ADA, federal law protected people with an impairment that limited major life functions like sight or mobility from discrimination.
