Detailing the relationship between the sexual structure of orchids and the insects that fertilize them, this was the first of three volumes that followed the publication of the Origin which contained supporting evidence for the author's theory of natural selection. Darwin concludes that plants are equal to animals in the marvels of their adaptation; for example, he observes that wind-pollinated flowers have no colours; it is only those insect-pollinated varieties that have bright coloured petals and sweet smelling nectars.

Again, the vessels supplying one of the lower sepals, the corner of the labellum, and one of the two stigmas (S), unite and form the antero-lateral group; and so with all the other vessels. Hence, if the existence of groups of spiral vessels can be trusted, and Dr. Hooker informs me that he has never known them to speak falsely, the flower of an Orchid certainly consists of fifteen organs, in a much modified and confluent condition. "We see three stigmas, with the two lower ones generally confluent, and with the upper one modified into the rostellum. We see six stamens, arranged in two whorls, with one alone (A 1) generally fertile. In Cypripedium, however, two stamens of the inner whorl (a 1 and a 2) are fertile, and in other Orchids these two are represented in various ways more plainly than the remaining stamens. The third stamen of the inner whorl (o 3), when its vessels can be traced, forms the front of the column: Brown thought that it often formed a medial excrescence, or ridge, cohering to the labellum; or, in the case of...

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an original discussion and analysis of epistemic peer disagreement. It reviews a wide range of cases from the literature, and extends the definition of epistemic peerhood with respect to the current one, to account for the actual variability found in real-world examples. The book offers a number of arguments supporting the variability in the nature and in the range of disagreements, and outlines the main benefits of disagreement among peers i.e. what the author calls the benefits to inquiry argument.

Download or read book Darwin's Most Wonderful Plants written by Ken Thompson and published by University of Chicago Press. This book was released on 2019-10-07 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many people, the story of Charles Darwin goes like this: he ventured to the Galapagos Islands on the Beagle, was inspired by the biodiversity of the birds he saw there, and immediately returned home to write his theory of evolution. But this simplified narrative is inaccurate and lacking: it leaves out a major part of Darwin’s legacy. He published On the Origin of Species nearly thirty years after his voyages. And much of his life was spent experimenting with and observing plants. Darwin was a brilliant and revolutionary botanist whose observations and theories were far ahead of his time. With Darwin’s Most Wonderful Plants, biologist and gardening expert Ken Thompson restores this important aspect of Darwin’s biography while also delighting in the botanical world that captivated the famous scientist. Thompson traces how well Darwin’s discoveries have held up, revealing that many are remarkably long-lasting. Some findings are only now being confirmed and extended by high-tech modern research, while some have been corrected through recent analysis. We learn from Thompson how Darwin used plants to shape his most famous theory and then later how he used that theory to further push the boundaries of botanical knowledge. We also get to look over Darwin’s shoulder as he labors, learning more about his approach to research and his astonishing capacity for hard work. Darwin’s genius was to see the wonder and the significance in the ordinary and mundane, in the things that most people wouldn’t look at twice. Both Thompson and Darwin share a love for our most wonderful plants and the remarkable secrets they can unlock. This book will instill that same joy in casual gardeners and botany aficionados alike.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first edition of Charles Darwin's On the Origin of Species, published on November 24, 1859 in London by John Murray. It is a seminal work in scientific literature and a landmark work in evolutionary biology. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. The starting chapters introduce the theory of natural selection, explaining why certain species thrive, while others decrease in number, how the members of nature are in competition with each other and why organisms tend to vary and change with time. Much of this work is based on experiments and observations seen within domestic animals and plants. The later chapters defend the theory of natural selection against apparent inconsistencies, why geological records are incomplete, why we find species so widespread and how sterility can be inherited when the organisation is unable to reproduce and more. The book is approachable for any audience.

Download or read book Orchid written by Jim Endersby and published by University of Chicago Press. This book was released on 2016-11-07 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prize-winning history of the orchid: “an engaging and enlightening account of one of the Earth's most mythologized botanical wonders” (Richard Conniff, author of House of Lost Worlds). At once delicate, exotic, and elegant, orchids are beloved for their singular, instantly recognizable beauty. Found in nearly every climate, the many species of orchid have had varying forms of significance in countless cultures over time. Following the orchid’s journey from Ancient Greek medicine to twentieth century detective novels, science historian Jim Endersby explores the flower’s four recurring themes: science, empire, sex, and death. Orchids were a symbol of the exotic riches sought by 19th century Europeans in their plans for colonization. They became subjects of scientific scrutiny for Charles Darwin, who investigated their methods of cross-pollination. As Endersby shows, orchids—perhaps because of their extraordinarily diverse colors, shapes, and sizes—have also bloomed repeatedly in films, novels, plays, and poems, from Shakespeare to science fiction. Featuring many gorgeous illustrations from the collection of the Royal Botanic Gardens, Kew, Orchid: A Cultural History was awarded the Watson Davis and Helen Miles Davis Prize by the History of Science Society. It is an enchanting tale not only for gardeners and plant collectors, but anyone curious about the flower’s obsessive hold on the imagination in history, cinema, literature, and more.
