"On the Origin of Species by Means of Natural Selection" is a seminal work written by Charles Darwin. First published in 1859, this book represents a landmark in the field of biology and is considered one of the most important scientific works ever written.In "On the Origin of Species," Charles Darwin presents his theory of evolution by natural selection. The central idea is that species evolve over time through the differential survival and reproduction of organisms with advantageous traits. Darwin provides a wealth of evidence from various scientific disciplines, including paleontology, embryology, and biogeography, to support his theory.The publication of this book had profound implications for the understanding of the diversity of life on Earth and challenged prevailing scientific and religious views at the time. Darwin's work laid the foundation for modern evolutionary biology and continues to influence scientific thought to this day.

"The Movements and Habits of Climbing Plants" is a book written by Charles Darwin. Originally published in 1875, it is a botanical work in which Darwin explores the behavior and adaptations of various climbing plants. This book is considered one of Darwin's later works, following his groundbreaking "On the Origin of Species."In "The Movements and Habits of Climbing Plants," Darwin investigates how certain plants exhibit climbing behaviors, the mechanisms they employ, and the advantages of climbing in their natural environments. He explores topics such as the role of twining, the movement of tendrils, and the ability of plants to adapt and reach for support in their surroundings.Darwin's observations and experiments in this book contribute to the broader understanding of plant biology and adaptation. While not as widely known as some of his other works, it reflects Darwin's meticulous approach to scientific inquiry and his curiosity about the natural world.

The Voyage of the Beagle, a maritime odyssey that unfolded in the early 19th century, stands as an extraordinary chapter in the annals of exploration, forever etching the HMS Beagle into the fabric of scientific history. Led by the intrepid Captain Robert FitzRoy, this maritime journey embarked in 1831, unfurling its sails to the winds of curiosity and discovery.Picture, if you will, the majestic vessel-a sleek, three-masted brigantine adorned with the Union Jack, cutting through the azure waves of the Atlantic Ocean. The Beagle was no ordinary ship; it was a floating laboratory, a crucible for scientific inquiry, with a young naturalist named Charles Darwin aboard. The ship's mission was ostensibly to chart the coast of South America, but its impact would transcend mere cartography.As the Beagle navigated the waters, it charted an intricate course, weaving through the labyrinth of the Galápagos archipelago, tracing the contours of the South American coastline, and anchoring in far-flung ports from Tierra del Fuego to Tahiti. Each landfall held a promise of discovery, a trove of new species, geological wonders, and cultural nuances waiting to be unraveled.The Galápagos Islands, an otherworldly realm in the Pacific, became a crucible of inspiration for Darwin. Here, he encountered an array of unique creatures, from giant tortoises to marine iguanas, each perfectly adapted to their isolated environments. These encounters sowed the seeds of his groundbreaking theory of evolution, the genesis of ideas that would reshape the very fabric of our understanding of life's tapestry.The Beagle's sojourn was not confined to biology alone; it danced through the realms of geology, anthropology, and meteorology. FitzRoy, a polymath in his own right, led surveys and experiments, collecting data that would enrich the scientific corpus for generations to come. The ship's deck, once reserved for the hustle of sailors, became a stage for the ballet of scientific inquiry, where specimens were cataloged, notes were scrawled, and hypotheses were born.Yet, this voyage was not without its trials. Storms battered the Beagle, testing the mettle of both ship and crew. The uncharted waters presented challenges that demanded resilience and determination. Through the tempests and trials, the Beagle persevered, emerging as a floating bastion of knowledge.The odyssey of the Beagle, spanning nearly five years, left an indelible mark on the scientific landscape. Its legacy resonates not only in the meticulous charts it produced but in the paradigm-shifting ideas born from the inquisitive mind of Charles Darwin. The journey of the Beagle transcends its nautical roots; it is a testament to the unyielding human spirit that yearns to explore the unknown, to unravel the mysteries that shroud our understanding of the world.As we reflect on the voyage of the Beagle, we are invited to envision the vast expanse of the open sea, to feel the spray of salt on our faces, and to marvel at the wonders of a world waiting to be discovered. The Beagle, with its billowing sails and insatiable curiosity, becomes not just a ship but a symbol-an emblem of human exploration, scientific enlightenment, and the boundless potential that lies beyond the horizon.

HarperCollins is proud to present its new range of best-loved, essential classics.'How fleeting are the wishes and efforts of man! how short his time! and consequently how poor will his products be, compared with those accumulated by nature during whole geological periods.'Still considered one of the most important and groundbreaking works of science ever written, Darwin's eminently readable exploration of the evolutionary process challenged most of the strong beliefs of the Western world. Forced to question the idea of the Creator, mid-nineteenth century readers were faced with Darwin's theories on the laws of natural selection and the randomness of evolution, causing massive controversy at the time. However, Darwin's theories remain instrumental in providing the backbone to modern biology today.

On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin that is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. The book presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had collected on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

"Geological Observations on South America," written by Charles Darwin, presents a comprehensive exploration of the geological features, formations, and natural history of the South American continent. Readers are compelled to continue reading to find out what happens next since the title character is so indulgent. The book is a compilation of Darwin's detailed observations and insights gathered during his famous voyage aboard the HMS Beagle from 1831 to 1836. In the book, Darwin meticulously documents the geological formations, fossils, and landscapes he encountered across South America, offering a fascinating account of the continent's geological history. He introduces readers to the concept of gradual geological change, challenging prevailing notions of cataclysmic events shaping the Earth's surface. One of the prominent features of the book is Darwin's description of the Andes mountain range and his analysis of the forces that led to its uplift. He theorized that the mountains were formed through a slow process of elevation, contradicting earlier beliefs in instantaneous upheavals. Additionally, he explored the origins of coral reefs, volcanic activity, and the effects of erosion on the landscape.

Perhaps the most readable and accessible of the great works of scientific imagination, On The Origin of Species sold out on the day it was published in 1859. Its popularity is still undiminished. Based largely on Darwin's experience as a naturalist while on a fiveyear voyage aboard H.M.S. Beagle, On the Origin of Species explains the mechanism of natural selection: the idea that made evolution scientifically intelligible for the first time. On the origin of Species is one f the landmark works that has helped shape the modern world. The book has fresh applications today for its pioneering views on the ecology of plants and animals.

Il soggetto del presente libro, vale a dire le diverse forme di fiori prodotti normalmente da certe specie di piante sullo stesso fusto o su fusti diversi, dovrebbe essere trattato da un botanico di professione, al qual titolo io non ho alcun diritto. Per quanto riguarda i rapporti sessuali dei fiori già Linneo avanti molto tempo introdusse la divisione di specie ermafroditiche, monoiche, dioiche e poligame. Questa distinzione fondamentale, coll¿aiuto di parecchie suddivisioni in ciascuna delle quattro classi, potrà servire al mio scopo; ma questa classificazione è artificiale, ed esistono fra questi gruppi frequenti passaggi.

È evidentissimo che i fiori del maggior numero delle piante, sono costruiti in modo da essere, o abitualmente o accidentalmente fecondati per incrocio, col mezzo del polline d¿un altro fiore posto, o sulla stessa pianta, o più generalmente, come vedremo in seguito, su una pianta diversa. Talvolta la fecondazione incrociata è assicurata dalla separazione dei sessi; il più delle volte essa lo è perchè la maturità del polline e dello stigma non avviene contemporaneamente. ¿ Tali piante si chiamano dicogame, e furono divise in due sottoclassi: le proterandre, nelle quali il polline matura prima dello stigma, e le protenogine, nelle quali avviene il contrario;
