I mean by this expression that the whole organisation is so tied together, during its growth and development, that when slight variations in any one part occur and are accumulated through natural selection, other parts become modified.
Esamolde honen bidez esan nahi dut organismo guztia hain elkarloturik dagoela bere hazkunde eta garapen guztian zehar, non, organoren batean aldakuntza txikiak gertatu eta hautespen naturalaren bidez metatzen direnean, beste organo batzuk ere eraldatu egiten diren.
