Thus, as I am inclined to believe, morphological differences, which we consider as important-such as the arrangement of the leaves, the divisions of the flower or of the ovarium, the position of the ovules, etc., first appeared in many cases as fluctuating variations, which sooner or later became constant through the nature of the organism and of the surrounding conditions, as well as through the intercrossing of distinct individuals, but not through natural selection; for as these morphological characters do not affect the welfare of the species, any slight deviations in them could not have been governed or accumulated through this latter agency.
Honenbestez, aiher nahiz uste izatera guk inportantetzat ditugun alde morfologikoak-hala nola hostoen atonkera, lorearen edo obulutegiaren banaketak, obuluen kokaera etab.-hasieran kasu askotan aldakuntza fluktuagarri gisa agertu zirela, lehentxeago edo geroxeago iraunkor bihurtu zirelarik, organismoaren eta inguruko baldintzen izaera, baita banako ezberdinen gurutzaketa ere bide, baina ez hautespen naturalez; izan ere, ezaugarri morfologiko hauek espeziearen ongizatean eraginik ez dutenez gero, hautespen naturalak ezin zezakeen beretan izaniko ezein desbideraketa arin erregula ez meta.
