And Of The Fiftieth Anniversary Of The Publication Of The Origin Of Species.

And Of The Fiftieth Anniversary Of The Publication Of The Origin Of Species.

On 27 August 1883, the island of Krakatau was destroyed in one of the most violent volcanic events ever recorded. This caused the 'year without a summer', thousands of deaths (mainly from tsunamis), fabulous sunsets and a measurable cooling of the oceans over nearly a century. Krakatau also provided evolutionary biologists with a unique opportunity to investigate the mechanisms of plant dispersal. This had been the subject of laborious research for Charles Darwin, who had speculated upon and, it seems, accurately postulated how an 'unstocked island' might be recolonised. In this 1908 volume, Alfred Ernst analysed the effects of wind, birds and sea currents in the transport not only of seeds but also of trees, branches and even of substantial animals. Krakatau's ecosystem, at a more primitive stage than that Darwin had seen on the Galapagos Islands, demonstrated how simple but continuous natural forces might re-establish a complex ecology.

The Cambridge Philosophical Society collected this series of essays in commemoration of the centenary of the birth of Charles Darwin and the 50th anniversary of the publication of The Origin of Species. Aiming to be accessible to the 'educated layman', the eminent contributors reviewed the impact of Darwin's ideas in many spheres. They addressed contemporary (1909) attitudes, Darwin's theories and their far-reaching implications, and the progress of new lines of research that had emerged from them. The diversity of views among biologists regarding both the origin of species and the best directions for further research is clearly evident. In his work, Darwin had sought only the truth, writing 'Absolute accuracy is the hardest merit to attain, and the highest merit. Any deviation is ruin.' However dramatic the controversies he stirred, what shines from these essays is profound admiration for both Darwin's intellect and the quality of his character.

Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. A. C. Seward's Links with the Past in the Plant World was first published in 1911 and reprinted in 1921. The purpose of the book was to enquire into the relative antiquity of existing plants and to throw light on evidence of plant life taken from the fossil record.

A. C. Seward (1863 1941) was an eminent English geologist and botanist who pioneered the study of palaeobotany. After graduating from St John's College, Cambridge, in 1886 Seward was appointed a University Lecturer in Botany in 1890. In 1898 he was elected a Fellow of the Royal Society, and was appointed Professor of Botany in 1906. These volumes, published to great acclaim between 1898 and 1919, provide a detailed discussion and study of an emerging science. In the early nineteenth century, research and critical literature concerning palaeobotany was scattered across disciplines. In these volumes Seward synthesised and revised this research and also included a substantial amount of new material. Furnished with concise descriptions of fossil plants, detailed figures and extensive bibliographies these volumes became the standard reference for palaeobotany well into the twentieth century. Volume 1, published in 1898, contains an overview of palaeobotany with systematic descriptions of fossil plants.

The author of the standard early twentieth-century textbook on fossil plants, A. C. Seward (1863 1941) was Professor of Botany at Cambridge, Master of Downing College and Vice-Chancellor of Cambridge University. This account of his first research trip to Greenland is an evocative portrait of the country, its immense and sublime landscape, its people, and life on the Danish scientific station. This little book, written in an engaging conversational tone, conveys Seward's enthusiasm for Greenland. It includes an explanation for non-specialists of some of Seward's findings relating to fossil plants found there, which provide evidence that the country had a much milder climate in previous geological periods. Seward's own photographs are a fascinating record of the traditional life of the Inuit population as it then survived, as well as the rugged scenery of icebergs and glaciers.

Henry Pearson (1870 1916) was an English botanist specialising in research on the Gnetophyta division of woody plants. In 1903 he was elected to the Henry Bolus Professorship of Botany at the South African College, Cape Town (now known as the University of Cape Town), and he was elected a Fellow of the Royal Society in 1916 shortly before his death. In 1915 Pearson was commissioned to write this volume for the Cambridge Botanical Handbooks series. Published posthumously in 1929, it was the first extensive study on the Gnetales order and the only such study in English published during the twentieth century. In it, Pearson investigates the morphology and reproduction of the three Gnetophyta genera and examines their relation to the angiosperms (flowering plants). His research on Gnetophyta was later used together with genetic studies to provide theories explaining the evolution of seed plants.

Published in 1931 to complement Seward's magisterial four-volume textbook Fossil Plants, this book is a digest of his earlier detailed study, written for a non-specialist audience as an introduction to the field of palaeobotany. Seward begins by describing the basics of geology and palaeobotany in order to explain how the interpretation of fossilised plant remains found in rocks can shed light on the natural world of prehistoric times. He then covers geological periods in chronological sequence, from the Pre-Cambrian to the Quaternary. Throughout, he emphasises the fragmentary nature of the evidence and the difficulties in extrapolating from the surviving fossil record, but he also explains the great discoveries made in the field and how they came about. The accompanying drawings give an impression of the likely combinations of plants found in each period, allowing the reader to visualise the different landscapes evoked in Seward's engaging prose.
