Phytoncide
Phytoncides are antimicrobial allelochemic volatile organic compounds derived from plants. The word, which means "exterminated by the plant", was coined in 1928 by Dr. Boris P. Tokin, a Russian biochemist from Leningrad University. He found that some plants give off very active substances that help to prevent them from rotting or being eaten by some insects and animals. Occurrence and function Cedar, garlic, locust, oak, onion, pine, tea tree, many spices, and many other plants give off phytoncides. Garlic contains allicin and diallyl disulfide. Pine contains alpha-pinene, carene, myrcene, and other terpenes. ''Sophora flavescens'' contains sophoraflavanone G. More than 5,000 volatile substances defend plants that protect them from bacteria, fungi, and insects. Phytoncides work by inhibiting or preventing the growth of the attacking organism. Use They are widely used in Russian, Ukrainian, Korean, Chinese, and Japanese medicine, as well as in alternative medicine, aromathera ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical School, ...
