The legendary biologist turns his attention to Botany, and this book is primarily of interest to botanists. For those who aren't botanists, it might be difficult to wade through all his talk about heterostyles and illegitimate pollination, but it's an interesting artifact for those of us who are so enamored of botany that we willingly made it our life's work. Most of the information is, of course, out of date, but it's always fun to see the history of the field, and to wonder if this work had anywhere near the wide distribution of his works on evolution and his travels. Not likely; this was a technical work designed to appeal to science geeks, and I suspect even in the Victorian era, when people were much more likely to wander through large works of technical density, this would have been a bit much. Overall, an interesting relic. ( ) aucune critique | ajouter une critique
After the publication of On the Origin of Species in 1859 Darwin became fascinated with the potential for botanical experiments to provide evidence for the process of evolution. First published in 1877, this volume is based on a series of papers concerning heterostylous plants (species which produce different types of flowers) originally published in the Journal of the Proceedings of the Linnaen Society in 1862. Linnaeus had divided the sexual relations of flowers into four groups, which Darwin uses as the structure for this volume. Darwin examines in detail plants which produce different flower forms, presenting his conclusions in terms of adaptive evolution and so providing the first functional interpretation of heterostyly. He demonstrates that these plants are adapted for cross-fertilisation, not self-fertilisation as was widely believed. The concepts which Darwin introduces in this volume continue to provide the basis for research into plant reproductive biology. Aucune description trouvée dans une bibliothèque |
