From a biological perspective, arranging leaves as far apart as possible in any given space is favoured by natural selection as it maximises access to resources, especially sunlight for photosynthesis.
Bioloogilisest vaatenurgast on lehtede asetamine üksteisest võimalikult kaugele kasulik loodusliku valiku seisukohast, kuna see suurendab ligipääsu ressurssidele, eriti päikesevalgusele.
