I would like to comment on Rzepa's following smart ideas:

...during the 1920s, Imperial College Chemistry was very well known for its natural product chemistry, and at one time we had a library of perhaps 1000 compounds isolated from nature. The folk lore was that the organisms which had originally produced these species by metabolism had long since mutated, and that these samples were now unique (ie no organism now known produced them any more).

This idead can become a very interesting research project! Many researches can be carried out on old samples!
