but we have also seen in the second chapter that the same principle applies to the whole individual; for in a district where many species of a genus are found-that is, where there has been much former variation and differentiation, or where the manufactory of new specific forms has been actively at work-in that district and among these species, we now find, on an average, most varieties.
baina bigarren kapituluan ikusi dugu banako guztiei ere hastapen bera aplikatzen zaiela; izan ere, genero bereko espezie asko topatzen den herrialdean-hau da, lehenago aldakuntza eta bereizkuntza asko egon den tokian, forma espezifiko berrien lantegia ekin eta ekin lanean ari izan den tokian-, hantxe eta espezie haiexetan topatzen dugu orain, batez beste, aldakuntzarik gehien.
