The uncanny resemblance of these vines to ropes, cables or DNA leads one to think that there must be something pretty special about this shape...
We build plywood by assembling thin sheets of wood together with glue, alternating the woods' grain with each layer. This gives a great amount of strength to the final sheet - a plane-shaped composite of layers - in a process called lamination. Picture now, the individual vines as lines, laminated together through twisting. If you look really close, you can see that where two lengths intersect, they are almost at a right angle to each other - or cross grained - just like the plywood. The DNA, it seems, is laminated through the cross-grains of its' rungs, and given added strength through its' twists. LIFE TOUR: THEM LAST 1 2 3 4 5 6 7 8 9 NEXT
