物種起源(英文修訂版)（簡體書）

《物種起源(英文修訂版)》內容簡介：Wited ON board H.M.S. Beagle, as naturalist, Lwas much struck with certainfacts in the distribution of the organic beings inhabiting South America. and in thegeological relations of the present to the past inhabitants of that continent. Thesefacts, as will be seen in the latter chapters of this volume, seemed to throw somelight on the origin of species——that mystery of mysteries, as it h~as been called byone of our greatest philosophers. On my return home. it occurred to me. in I837,that something might perhaps be made out on this question by pxatiently accumulating and reflecting on all sorts of facts which could possibly have anybearing on it. After five years work 1 allowed myself to speculate on the subject.and drew up some short notes; these I enlarged in I844 into a sketch of theconclusions, which then seemed to me probable: from that period to the presentday I have steadily pursued the same object. I hope that I may be excused forentering on these personal details, as I give them to show that I have not beenhasty in coming to a decision.

作者：（英國）達爾文（Charles Darwin）

達爾文，Charles Robert Darwin (i800-1882) was a splendid English naturalist who established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection. Iie published his theory with compelling evidence for evolution in his 1859 book On the Origin of Species. The scientific community and much of the general public came to accept ewolution as a fact in his lifetime, but it was not until the emergence of the modern evolutionary svnthesis from the 193os to the 195os that a broad consensus devel ped that natural selection was the basic mechanism of evolution.
Darwins work has continued to be celebrated by numerous publications and events. Darwin Day has become an annual celebration, and in 2009 w達爾文，rldwide events were arranged for the bicentenary of Darwins birth and the 15oth anniversary of the pt, blication of On the Origin of Species.

PREFACE
INTRODUCTION
CHAPTER I VARIATION UNDER　DOMESTICATION
Causes of variability
Effects of habit and of the use or disuse of parks; Correlated variation;Inheritance
Character of domestic varieties; Difficulty of distinguishing between varieties and species; Origin of domestic varieties from one or more species
Breeds of the domestic pigeon, Their differences and origin
Principles of selection anciently followed, and their effects
Unconscious selection
Circumstances favourable to mans power of selection

CHAPTER II VARIATION UNDER NATURE
Individual differences
Doubtful species
Wide-ranging, much diffused, and common species vary most
Species of the larger genera in each country vary more frequently than the species of the smaller genera
Many of the species included within the larger genera
resemble varieties in being very closely, but unequally,related to each other, and in having restricted ranges
Summary

The term, struggle for existence, used in a large sense
Geometrical ratio of increase
Nature of the checks to increase
Complex relations of all animals and plants to each other in the struggle for existence
Struggle for life most severe between individuals and vareties of the same species

CHAPTER IV NATURAL SELECTION; OR THE SURVIVAL OF THE FITTEST
Sexual selection
Illustrations of the action of natural selection, or the survival of the fittest
On the intercrossing of individuals
Circumstances favourable for the production of new forms through natural selection
