Human uses of living things of genes. Basic biological research has often been done with plants. In genetics, the breeding of pea plants allowed Gregor Mendel to derive the basic laws governing inheritance, and examination of chromosomes in maize allowed Barbara McClintock to demonstrate their connection to inherited traits. The plant "Arabidopsis thaliana" is used in laboratories as a model organism to understand how genes control the growth and development of plant structures. Space stations or space colonies may one day rely on plants for life support. Vaccines have been made using animals since their discovery by Edward Jenner in the 18th century. He noted
Order of Saint Augustine the members of the order, but it was the great scientist Johann Gregor Mendel, abbot of the Czech monastery of St. Thomas at Old Brno in Moravia (d. 1884) who gave great credit to the Augustinian Order's scholarship in the 19th century. He was the discoverer of the Mendelian laws of heredity and hybridization. Given that the Roman Catholic Church in the Western world has been experiencing a decline in vocations to the priesthood and religious life since the 1960s, a relatively simple way to assess the vigour of this order is to compare the numbers of those in solemn
