Further to “Deep sea fish uses tripod to ‘stand’,” Phys.org alerts us to a fish with a previously unknown type of eye. From Phys.org:
The aptly-named glasshead barreleye lives at depths of 800 to 1000 meters. It has a cylindrical eye pointing upwards to see prey, predators or potential mates silhouetted against the gloomy light above. But the eye also has a mirror-like second retina which can detect bioluminescent flashes created by deep-sea denizens to the sides and below
The light coming from below is focused onto a second retina by a curved mirror composed of many layers of small reflective plates made of guanine crystals, giving the fish a much bigger field of vision.
Watch the legacy mainstream media rush to ignore this one:
The glasshead barreleye is therefore one of only two vertebrates known to have reflector eyes; but significantly, although rhynchohyalus natalensis and dolichopteryx longipes belong to the same family, their reflective lenses have a different structure and appear to have developed from different kinds of tissue. That indicates that two related but different genera took different paths to arrive at a similar solution – the reflective optics and a second retina to supplement the limited vision of the conventional refractive cylindrical eye.
Convergent evolution in different genera.
And, of course, we will hear that scientists explain that the fish evolved this way *so that it can* detect predators, prey, and potential mates. Like we said before, that is not an explanation of how it evolved, only of what the system can currently do. In this case, two different highly complex systems, convergently “evolved” to fulfil these functions.
Readers, do you ever get the feeling, listening to Darwin-approved news copy, that you are listening to a sociopath on the witness stand in a criminal court case? It’s all specialized terminology for obfuscation of basic issues like “What exactly happened?” “Did you actually see this?”
