So again, if the three families formed of eight genera (a14 to m14), on the uppermost line, be supposed to differ from each other by half-a-dozen important characters, then the families which existed at a period marked VI would certainly have differed from each other by a less number of characters; for they would at this early stage of descent have diverged in a less degree from their common progenitor.
Era berean, baldin goiko lerroaren gainean dauden zortzi generoek osaturiko hiru familiak dozenerdi ezaugarri inportantetan ezberdinak direla suposatuz gero, orduan VI. lerroak seinalaturiko aldian bizi izan ziren familiak ezaugarri gutxiagotan izan ziratekeen ziurrenik ezberdinak, ondorengotzako maila goiztiar honetan beren gurasolehenarengandik hain aldendurik aurkitu ez ziratekeelako.
