BOOK: Darwin’s Orchids: Then and Now

An academic volume has resulted from a a day-long symposium held within the International Botanical Congress in Melbourne, Australia in 2011. The research in the book serves as a comparison of Darwin’s work and books on orchids (2012 was the 150th anniversary of the publication of Fertilisation of Orchids) in the mid-nineteenth century to research conducted by scientists since then.

Publisher’s description For biologists, 2009 was an epochal year: the bicentennial of Charles Darwin’s birth and the 150th anniversary of the publication of a book now known simply as The Origin of Species. But for many botanists, Darwin’s true legacy starts with the 1862 publication of another volume: On the Various Contrivances by Which British and Foreign Orchids Are Fertilised by Insects and on the Good Effects of Intercrossing, or Fertilisation of Orchids. This slim but detailed book with the improbably long title was the first in a series of plant studies by Darwin that continues to serve as a global exemplar in the field of evolutionary botany. In Darwin’s Orchids, an international group of orchid biologists unites to celebrate and explore the continuum that stretches from Darwin’s groundbreaking orchid research to that of today. Mirroring the structure of Fertilisation of Orchids, Darwin’s Orchids investigates flowers from Darwin’s home in England, through the southern hemisphere, and on to North America and China as it seeks to address a set of questions first put forward by Darwin himself: What pollinates this particular type of orchid? How does its pollination mechanism work? Will an orchid self-pollinate or is an insect or other animal vector required? And how has this orchid’s lineage changed over time? Diverse in their colors, forms, aromas, and pollination schemes, orchids have long been considered ideal models for the study of plant evolution and conservation. Looking to the past, present, and future of botany, Darwin’s Orchids will be a vital addition to this tradition.

BOOK: A Garden of Marvels

Readers of this blog might find this new book of interest, as chapters 25 and 28 (they’re short chapters!) look at Darwin’s “botanophilia,” specifically his studies of orchids and plant reproduction, climbing plants, and carnivorous plants.

Ruth Kassinger, A Garden of Marvels: How We Discovered that Flowers Have Sex, Leaves Eat Air, and Other Secrets of Plants (New York: William Morrow, 2014), 416pp.

In the tradition of The Botany of Desire and Wicked Plants, a witty and engaging history of the first botanists interwoven with stories of today’s extraordinary plants found in the garden and the lab.

In Paradise Under Glass, Ruth Kassinger recounted with grace and humor her journey from brown thumb to green, sharing lessons she learned from building a home conservatory in the wake of a devastating personal crisis.

In A Garden of Marvels, she extends the story. Frustrated by plants that fail to thrive, she sets out to understand the basics of botany in order to become a better gardener. She retraces the progress of the first botanists who banished myths and misunderstandings and discovered that flowers have sex, leaves eat air, roots choose their food, and hormones make morning glories climb fence posts. She also visits modern gardens, farms, and labs to discover the science behind extraordinary plants like one-ton pumpkins, a truly black petunia, a biofuel grass that grows twelve feet tall, and the world’s only photosynthesizing animal. Transferring her insights to her own garden, she nurtures a “cocktail” tree that bears five kinds of fruit, cures a Buddha’s Hand plant with beneficial fungi, and gets a tree to text her when it’s thirsty.

Intertwining personal anecdote, accessible science, and untold history, the ever-engaging author takes us on an eye-opening journey into her garden—and yours.

Botanical Smuts and Hermaphrodites: Lydia Becker, Darwin’s Botany, and Education Reform

Tina Gianquitto

Abstract In 1868, Lydia Becker (1827–1890), the renowned Manchester suffragist, announced in a talk before the British Association for the Advancement of Science that the mind had no sex. A year later, she presented original botanical research at the BAAS, contending that a parasitic fungus forced normally single-sex female flowers of Lychnis diurna to develop stamens and become hermaphroditic. This essay uncovers the complex relationship between Lydia Becker’s botanical research and her stance on women’s rights by investigating how her interest in evolutionary theory, as well as her correspondence with Charles Darwin, critically informed her reform agendas by providing her with a new vocabulary for advocating for equality. One of the facts that Becker took away from her work on Lychnis was that even supposedly fixed, dichotomous categories such as biological sex became unfocused under the evolutionary lens. The details of evolutionary theory, from specific arguments on structural adaptations to more encompassing theories on heredity (i.e., pangenesis), informed Becker’s understanding of human physiology. At the same time, Becker’s belief in the fundamental equality of the sexes enabled her to perceive the distinction between inherent, biological differences and culturally contingent ones. She applied biological principles to social constructs as she asked: Do analogous evolutionary forces act on humans?

BOOK: The Darwin Archipelago: The Naturalist’s Career Beyond Origin of Species

The Darwin Archipelago: The Naturalist’s Career Beyond Origin of Species, by Steve Jones (New Haven, CT: Yale University Press, 2011), 248 pp.

Charles Darwin is of course best known for The Voyage of the Beagle and The Origin of Species. But he produced many other books over his long career, exploring specific aspects of the theory of evolution by natural selection in greater depth. The eminent evolutionary biologist Steve Jones uses these lesser-known works as springboards to examine how their essential ideas have generated whole fields of modern biology.

Earthworms helped found modern soil science, Expression of the Emotions helped found comparative psychology, and Self-Fertilization and Forms of Flowers were important early works on the origin of sex. Through this delightful introduction to Darwin’s oeuvre, one begins to see Darwin’s role in biology as resembling Einstein’s in physics: he didn’t have one brilliant idea but many and in fact made some seminal contribution to practically every field of evolutionary study. Though these lesser-known works may seem disconnected, Jones points out that they all share a common theme: the power of small means over time to produce gigantic ends. Called a “world of wonders” by the Times of London, The Darwin Archipelago will expand any reader’s view of Darwin’s genius and will demonstrate how all of biology, like life itself, descends from a common ancestor.

Get to Know Darwin

Carl Zimmer blogged about some new resources from the Darwin Correspondence Project, “Creating Young Darwins.” Based on a university course at Harvard, “Get to Know Darwin” equips educators (and parents!) curriculum for teaching students (or children!) about Darwin’s many experiments. Through some of his papers and letters, they can learn why Darwin did them, how they were conducted, his results, and the context of their connection to his theoretical work.

Integrating Darwin’s correspondence with exercises in experimental science and study of his published work has been a great success. For students in the course, reading the letters enriched their understanding of Darwin’s life and work. The letters provided “a glimpse of his thought process” and “brought the other works we were looking at to life, and gave much context to who Darwin was from childhood to old age, as a father and a husband, and ultimately as a scientist.” They showed students “what excited him, what his hobbies were, and what went on in his daily life.” This kind of historical texture was not merely incidental to students’ learning. As one student in the course put it, “These details may not be present in On the Origin of Species, but they are, in my opinion, an integral part of the full comprehension of it. Knowing that Darwin was a devoted family man, meticulous observer, and a charming individual is more than just interesting – it gives his published work more purpose.”

Here’s the list of available topics: Early Days, Barnacles, Biogeography, Variation Under Domestication, Orchids, Instinct and the Evolution of Mind, Insectivorous Plants, Climbing Plants, Floral Dimorphism, Power of Movement in Plants, and Earthworms.

Bringing the history of science alive for education. I love it!
