Mendelian inheritance inheritance were named for and first derived by Gregor Johann Mendel, a nineteenth-century Moravian monk who formulated his ideas after conducting simple hybridisation experiments with pea plants ("Pisum sativum") he had planted in the garden of his monastery. Between 1856 and 1863, Mendel cultivated and tested some 5,000 pea plants. From these experiments, he induced two generalizations which later became known as "Mendel's Principles of Heredity" or "Mendelian inheritance". He described these principles in a two-part paper, "Versuche über Pflanzen-Hybriden" ("Experiments on Plant Hybridization"), that he read to the Natural History Society of Brno on 8 February and 8 March
Role of Christianity in civilization contribute to a deeper understanding of revelation, and so encouraged intellectual development. The Church's priest-scientists, many of whom were Jesuits, have been among the leading lights in astronomy, genetics, geomagnetism, meteorology, seismology, and solar physics, becoming some of the "fathers" of these sciences. Examples include important churchmen such as the Augustinian abbot Gregor Mendel (pioneer in the study of genetics), the monk William of Ockham who developed Ockham's Razor, Roger Bacon (a Franciscan friar who was one of the early advocates of the scientific method), and Belgian priest Georges Lemaître (the first to propose the Big Bang theory).
