物种起源 - Tapa blanda

Sinopsis

在《物种起源》中，查尔斯·达尔文重点阐述和论证了高等生物是由低等生物逐渐演变而来的进化论思想，并提出了以自然选择、适者生存为基础的生物进化学说。《物种起源》的问世，第1次将生物学建立在完全科学的基础之上，颠覆了自然历史的基础学说。它不仅使人类对自身的认识发生了质的飞跃，也让人们知道生命和物种来源于大自然。同时，《物种起源》为社会哲学提供了一个全新、独特的思维空间，为现代生物科学奠定了坚实的理论基础。《物种起源》：CausesofVariability.EffectsofHabit.CorrelationofGrowth.Inheritance.Characterof-DomesticVarieties.DifficultyofdistinguishingbetweenVarietiesandSpecies.OriginofDomesticVarietiesfromoneormoreSpecies.DomesticPigeons,theirDifferencesandOrigin.PrincipleofSelectionancientlyfollowed,itsEffects.MethodicalandUnconsciousSelection.UnknownOriginofourDomesticProductions.CircumstancesfavourabletoMan'spowerofSelection.Whenwelooktotheindividualsofthesamevarietyorsub-varietyofouroldercultivatedplantsandanimals,oneofthefirstpointswhich-strikesus,is,thattheygenerallydiffermuchmorefromeachother,thandotheindividualsofanyonespeciesorvarietyinastateofnature.Whenwereflectonthevastdiversityoftheplantsandanimalswhichhavebeencultivated,andwhichhavevariedduringallagesunderthemostdifferentclimatesandtreatment,Ithinkwearedriventoconcludethatthisgreatervariabilityissimplyduetoourdomesticproductionshavingbeenraisedunderconditionsoflifenotsouniformas,andsomewhatdifferentfrom,thosetowhichtheparent-specieshavebeenexposedundernature.Thereis,also,Ithink,someprobabilityintheviewpropoundedbyAndrewKnight,thatthisvariabilitymaybepartlyconnectedwith
