Mr. Herbert Spencer would probably answer that, as soon as simple unicellular organisms came by growth or division to be compounded of several cells, or became attached to any supporting surface, his law "that homologous units of any order become differentiated in proportion as their relations to incident forces become different" would come into action.
Herbert Spencer jaunak seguraski erantzunen luke organismo zelulabakar xumea hazkundez edo banaketaz zelula bat baino gehiagok osatua izatera heldu bezain laster, edo sostengu-azaleraren bati atxekirik gertatu zenean, indarrean jarri zela bere legea, hots, "unitate homologoak, zeinahi ordenatan, indar intzidenteekin dituzten erlazioak ezberdin bihurtzen diren heinean ezberdintzen direla".
