Botany, plant science(s), or plant biology (from Ancient Greek βοτάνη botane, "pasture, grass, or fodder" and that from βόσκειν boskein, "to feed or to graze"), a discipline of biology, is the science of plant life. Traditionally, the science included the study of fungi, algae, and viruses.
Botany covers a wide range of scientific disciplines including structure, growth, reproduction, metabolism, development, diseases, chemical properties, and evolutionary relationships among taxonomic groups. Botany began with early human efforts to identify edible, medicinal and poisonous plants, making it one of the oldest branches of science. Nowadays, botanists study about 400,000 species of living organisms.
The beginnings of modern-style classification systems can be traced to the 1500s-1600s when several attempts were made to scientifically classify plants. In the 19th and 20th centuries, major new techniques were developed for studying plants, including microscopy, chromosome counting, and analysis of plant chemistry. In the last two decades of the 20th century, DNA was used to more accurately classify plants.
Reverend James Warren "Jim" Jones (May 13, 1931 – November 18, 1978) was the founder and leader of the Peoples Temple, which is best known for the November 18, 1978 mass suicide of 909 Temple members in Jonestown, Guyana along with the killings of five other people at a nearby airstrip. Over 200 children were murdered at Jonestown, almost all of whom were forcibly made to ingest cyanide by the elite Temple members.
Jones was born in Indiana and started the Temple in that state in the 1950s. Jones and the Temple later moved to California, and both gained notoriety with the move of the Temple's headquarters to San Francisco in the mid-1970s.
The incident in Guyana ranks among the largest mass suicides in history, though most likely it involved forced suicide and/or murder, and was the single greatest loss of American civilian life in a non-natural disaster until the events of September 11, 2001. Among the dead was Leo Ryan, who remains the only Congressman assassinated in the line of duty as a Congressman in the history of the United States.
