Mivart remarks, "As, according to Mr. Darwin's theory, there is a constant tendency to indefinite variation, and as the minute incipient variations will be in ALL DIRECTIONS, they must tend to neutralize each other, and at first to form such unstable modifications that it is difficult, if not impossible, to see how such indefinite oscillations of infinitesimal beginnings can ever build up a sufficiently appreciable resemblance to a leaf, bamboo, or other object, for natural selection to seize upon and perpetuate."
"Darwin jaunaren teoriaren arabera mugagabeko aldakuntzarako joera etengabea denez eta aldakuntza txiki hasberriak norabide guztietan izan behar dutenez gero, elkar neutralizatzera eta, hasieran, eraldaketa hain ezegonkorrak sortzera jo behar dute, eta hor zaila da, ezinezko ez bada, ikustea gorabehera zehazgabe infinitesimalok nola era dezaketen hautespen naturalak atzeman eta betikotzeko moduko hosto, kanabera edo beste gauza baten antz hautemangarririk".
