Elephant’s trunk shows the effect of intellectual design

“The elephant proboscis (trunk) exhibits an extraordinary kinematic versatility as it can manipulate a single blade of grass but also carry loads up to 270 kilograms. “

Now. scientist ar the University of Geneva (UNIGE), Switzerland, “showed have the elephant trunk emerges from the combination of a finite set of basic movements such as the propagation of an inward curvature and the formation of pseudo-joints.”

“The elephant trunk is flexible across its whole length: the coordinated contractions of the muscles result in twisting, bending, lengthening, shortening and stiffening, without any bone support.”

This is a source of intelligent desIgn, not evolution as the University of Geneva claims. the elephant cannot have evolved a better trunk, but god put it there at the beginning.

Many other features in animals bear the hallmarks of intelligent design. A recent study looked at the zebra’s tail, which is also a very effective tool.

Other examples include 
the Saiga antelope’s air-conditioning nose, the penguin’s anti-free feathers and an anti-crash system in birds, to mention just a few.
