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

WItEN 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'pxatientlyaccumulating 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.

《物种起源(英文修订版)》In I831, Darwin set out on H.M.S. Beagle as a self-financcd gentleman companion to the z0 year-old captain. Robert Fitzrov. On the Galapagos Islands in the Pacific Ocean he noticed many variations among plants and animals of the same general type as those in South America. The exdiio visited places around the world, and Darwin studied plants and animals evervwhere he went. Collecting specimens for further study.
Upon his return to London in t836. Darwin conducted thorou&nsp;research of his notes and] specimens. Out of this study grew several related theories: one. evolution did occur: two. evolutionarv change was gradual, requiring thousands to millions ofvears: three, the primary mechanism for evolution was a process called natural selection; and four, the millions of species alive today arose from a single original life form throu&nsp;a branching process called "speciation."
1831年12月，刚刚从剑桥大学的达尔文以博物学家的身份搭乘英国海军的小猎犬号的往美洲，开始了为期五年的科学考察。准也不曾料想到，人类有史以来*深刻的思想由此拉开序幕：达尔文通过大量的事实明，人类不是由上帝创造的，而是由猿猴进化来的。这是当时的人们尤其是教会人士无论如何没法接受的，难怪他们要在漫画中将他画成一只阴郁的猴子了。
在近代目前，达尔文的进化论对中国知识界的影响更是
建议上架：英语读物无与伦比。经过严复等一批进步思想家的介绍、翻译，“物竟天择，适者生存”的思想在清木的社会中亦如石破天惊，成为现代思想运动的起点，一时间仁人志士以进化论的观点提倡鼓民力、开民智、新民德，号召救亡图存，可以说无一不从逃化论始。
