Frank Rattray Lillie
Frank Rattray Lillie (June 27, 1870November 5, 1947) was an American zoologist and an early pioneer of the study of embryology. Born in Toronto, Ontario, Canada, Lillie moved to the United States in 1891 to study for a summer at the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts. Lillie formed a lifelong association with the laboratory, eventually rising to become its director in 1908. His efforts developed the MBL into a full-time institution. Lillie was appointed an Assistant Professor at the University of Chicago in 1900. He was named Chairman of the Department of Zoology in 1910 and Dean of the Division of Biological Sciences in 1931. His research there was instrumental in the development of the field of embryology. He identified the influence of potassium on cell differentiation and elucidated the biological mechanisms behind free-martins. Lillie was instrumental in founding the Woods Hole Oceanographic Institution and served as its first president. He also s ...

Toronto
Toronto ( ; or ) is the capital city of the Canadian province of Ontario. With a recorded population of 2,794,356 in 2021, it is the most populous city in Canada and the fourth most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,765,188 people (as of 2021) surrounding the western end of Lake Ontario, while the Greater Toronto Area proper had a 2021 population of 6,712,341. Toronto is an international centre of business, finance, arts, sports and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world. Indigenous peoples have travelled through and inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and later designat ...

Embryology
Embryology (from Greek ἔμβρυον, ''embryon'', "the unborn, embryo"; and -λογία, '' -logia'') is the branch of animal biology that studies the prenatal development of gametes (sex cells), fertilization, and development of embryos and fetuses. Additionally, embryology encompasses the study of congenital disorders that occur before birth, known as teratology. Early embryology was proposed by Marcello Malpighi, and known as preformationism, the theory that organisms develop from pre-existing miniature versions of themselves. Aristotle proposed the theory that is now accepted, epigenesis. Epigenesis is the idea that organisms develop from seed or egg in a sequence of steps. Modern embryology, developed from the work of Karl Ernst von Baer, though accurate observations had been made in Italy by anatomists such as Aldrovandi and Leonardo da Vinci in the Renaissance. Comparative embryology Preformationism and epigenesis As recently as the 18th century, the prevailin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Otis Whitman
Charles Otis Whitman (December 6, 1842 – December 14, 1910) was an American zoologist, who was influential to the founding of classical ethology (study of animal behavior). A dedicated educator who preferred to teach a few research students at a time, he made major contributions in the areas of evolution and embryology of worms, comparative anatomy, heredity, and animal behaviour. He was known as the "Father of Zoology" in Japan. Biography Whitman was born in Woodstock, Maine. His parents were Adventist pacifists and prevented his efforts to enlist in the Union army in 1862. He worked as a part-time teacher and converted to Unitarianism. He graduated from Bowdoin College in 1868. Following graduation, Whitman became principal of the Westford Academy, a small Unitarian-oriented college preparatory school outside Lowell, Massachusetts. In 1872 he moved to Boston and after becoming a member of the Boston Society of Natural History in 1874, he decided to study zoology full-time. In ...

Endocrinology
Endocrinology (from '' endocrine'' + '' -ology'') is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones. It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction, and sensory perception caused by hormones. Specializations include behavioral endocrinology and comparative endocrinology. The endocrine system consists of several glands, all in different parts of the body, that secrete hormones directly into the blood rather than into a duct system. Therefore, endocrine glands are regarded as ductless glands. Hormones have many different functions and modes of action; one hormone may have several effects on different target organs, and, conversely, one target orga ...

Theology
Theology is the systematic study of the nature of the divine and, more broadly, of religious belief. It is taught as an academic discipline, typically in universities and seminaries. It occupies itself with the unique content of analyzing the supernatural, but also deals with religious epistemology, asks and seeks to answer the question of revelation. Revelation pertains to the acceptance of God, gods, or deities, as not only transcendent or above the natural world, but also willing and able to interact with the natural world and, in particular, to reveal themselves to humankind. While theology has turned into a secular field , religious adherents still consider theology to be a discipline that helps them live and understand concepts such as life and love and that helps them lead lives of obedience to the deities they follow or worship. Theologians use various forms of analysis and argument ( experiential, philosophical, ethnographic, historical, and others) to help understa ...
