Entanglement in Biology

Already in early times of quantum theory, its possible role within biology was discussed. In recent years, significant progress has been made with experiments on entanglement. It was found (among other results) that the conditions for entanglement to arise can be loosened, its observation becomes easier and more accurate, and its chances to persist under adverse conditions gradually improve. Particularly it was detected that entanglement can occur and persist under higher temperatures than supposed before.
