In consolidating his ideas about natural selection, and in considering orchids as being “universally acknowledged to rank amongst the most singular and most modified forms in the vegetable kingdom”, Charles Darwin (1809–1882) was already making concrete observations on, and evolutionary links between, insects and plants in the first edition of his book published in early 1862. One can endeavour to trace the history of evolutionary biology and come to the recognition that Darwin’s book on orchids generated the impetus for all succeeding investigations into coevolution and the evolution of extreme specialization.
