Original Text

Where do all these bizarre adaptations come from? Random genetic mutations in orchids may result in a trait– like a scent or a shape– that, by chance, matches the needs of a single insect species. The huge diversity within the insect world also increases the likelihood that an orchid will find a unique audience. Able to make more seeds and offspring with the help of its dedicated pollinators, the orchid successfully reproduces in isolation, and becomes a new species. But because of their dependence on sometimes just one pollinator species, orchids are also vulnerable, and many quickly go extinct.
