We shall also have two very distinct genera descended from (I), differing widely from the descendants of (A). These two groups of genera will thus form two distinct families, or orders, according to the amount of divergent modification supposed to be represented in the diagram.
(I)-tik sorturiko bi genero oso bereizi ere izanen ditugu, (A)-tik sorturikoen oso ezberdinak. Bi genero talde hauek, horrela, bi familia bereizi, edo ordena, eginen dituzte, diagraman irudikaturik suposatzen den eraldaketa dibergentearen zenbatekoaren arabera.
