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.

Sight itself is an intricate process. 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, each of our eyes records a slightly different version of what is observed. These two different views are then accurately merged in our brains to produce a single image—computationally using the differences between the two images to allow us to visually gauge depth and distance. This process, referred to as stereo vision, isn’t unique to humans. Animals like monkeys, dogs, bats, cats, and horses also use it.

Interestingly, in the vast world of insects, the only creature to have stereo vision is the praying mantis. This is a big conundrum to evolutionists because all other types of insects have eyes on the sides of their heads—a visual set-up which requires a completely different type of neurological processing system.
