Orchids was the first of the botanical books which Darwin published from 1862, all of which 'exalted' plants and showed how closely linked to animals they are. Several of these books, such as Cross and self-fertilisation (1876), developed the sexual theme initiated in Orchids.
It was concerned with working out in detail the relationships between sexual structures of orchids and the insects which fertilise them, their evolution being attributed to natural selection. It is therefore the first of the volumes of supporting evidence.
12 feb 2018 · He suggested that cross-fertilisation – in which one plant is fertilised by pollen from another – would increase a plant’s genetic fitness and provide the diversity needed for natural selection, leading to evolution and the development of new species.
TLDR. Direct observations, infra-red cinematography and photographs published between 1993 and 1997 and a video made in 2004, proved that Darwin's prediction was accurate and suggested that selection pressure exerted by predators on the pollinators, resulted in the evolution of extreme tongue lengths and a special hovering flight.
