The Society for Experimental Biology believes that the broad nature and lack of “ology” boundaries implicit in Experimental Biology give it a pivotal role in the development of Life Sciences which are of considerable benefit to its members and to society. In particular, Experimental Biology contributes to knowledge that can be applied to the development of agriculture and medicine and to understanding the impacts of human activity on living organisms and ecosystems.
