The Madagascar orchid that helped shape the theory of evolution
Discover the mystery behind Darwin's orchid, a spectacular species from Madagascar with a nectar spur over a foot long. This video explores the botanical puzzle that once left even Charles Darwin questioning how such a deep nectar well could be pollinated.
In this episode of Dig Depper, Princess of Wales Conservatory Supervisor Soléne Dequiret examines the unique anatomy of Darwin's orchid. The plant features a nectar reservoir tucked at the end of a spur measuring more than twelve inches in length. This extreme structure posed a significant challenge to naturalists, famously prompting Charles Darwin to wonder what insect possessed the capability to reach the nectar. Solving such botanical mysteries was instrumental in the development of his theory of evolution.
