Praying Mantis Vision Opposes Evolution
Humans and several critters have what is called stereo vision, which gives us the ability to ascertain depth, distance, and so forth. Such vision is not all that uncommon, but you would not expect to realize that the praying mantis is the only insect known to have this ability.

Light is received by the eye, then the brain processes the information so that the organism can make sense of it, often in a hurry. (Ever see a horse shy away from a rattlesnake that it saw but the rider didn't?) 3-D vision is even more complicated. It alone is in opposition to molecules-to-mantis evolution, but to be found in an insect is further evidence of the Master Engineer's craftsmanship. The research on these critters is rather fascinating, and I found it a bit amusing as well. In the animal kingdom, many types of creatures use stereo vision to determine the distances between them and visible objects. In humans, eac
