The lesser-known Darwin: what role did an orchid play in the theory of evolution?

BarcelonaIn the historic Down House, the home where Charles Darwin lived for 40 years in Kent, England, there was a space that was key to developing the theory of evolution that would bring the English naturalist worldwide fame. And it's not the table where he wrote The Origin of Speciesbut rather his garden. There, Darwin spent hours conducting small experiments with plants, such as the so-called Darwin's orchid or Christmas orchid, from Madagascar. It is a very particular species, with an extraordinarily long nectary, over 20 centimeters. The scientist predicted the existence of an insect capable of reaching the hidden nectar. The butterfly would be discovered decades later, confirming an intuition based solely on botanical observation.

"When we talk about Darwin, we always think of the Darwin of the finches, of the Galapagos. But, in reality, what people don't know is that Darwin was an extraordinary botanist and that he dedicated six books to the subject. This is unknown to the general public," says Martí Domínguez, curator of the exhibition on March 7, who, precisely, highlights the botanical dimension of Charles Darwin and invites the public to rediscover the scientist from this lesser-known perspective.

The central thesis of the exhibition is clear: without his research on orchids, carnivorous plants, and plant movement, the theory of evolution would be incomplete. Domínguez has spent years studying Darwin's work and emphasizes the need to correct an incomplete image of the English naturalist.

Installed in the Greenhouse of the Ciutadella Park, Darwin, botanist It proposes a journey through the biologist's more hidden side, with live plants and historical specimens. One of them is, of course, Darwin's orchid. "It's an extraordinary piece, a highly sought-after species," says the curator.

The exhibition also aims to recreate, through its set design, the domestic environment in which the biologist worked, reproducing what Darwin's greenhouse/garden was like in a way that... roughly speakingThe Barcelona Greenhouse thus becomes a bridge between Down House in Kent and the Ciutadella, between the 19th and 21st centuries. With this exhibition, the museum invites us to look beyond the finches. This more hidden side of Darwin is not a minor appendage, but a key piece of his intellectual legacy. Among the plants, the public will be able to discover a patient scientist obsessed with floral details.

The innovative nature of the project is emphasized. "It's a commitment to transmitting, in this case, evolutionary and botanical knowledge to society and to demonstrating that, with all the unique characteristics of this building, they are also capable of producing exhibitions of great scientific, historical, and heritage interest," says Carles Lalueza-Fox, director of the MCNB. The logistical challenge is considerable: species adapted to very diverse conditions coexist in the same space, some of them in full bloom to illustrate Darwinian experiments on pollination and reproduction. The exhibition is also a statement of intent regarding the role of the Greenhouse as a scientific facility. "This exhibition demonstrates that this facility we have can also serve as a cultural and scientific resource, in addition to its obvious heritage and aesthetic value," adds Lalueza-Fox. The goal is to transmit evolutionary and botanical knowledge to the general public, demonstrating that the history of science can also be told with real leaves, roots, and flowers.
