If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find out no such case.
In short order Darwin converted the profound into the mundane. But the facts of biology wouldn't cooperate. The farther back evolutionists peered in time the more complexity they found.
The third eye is a good example but new research takes the complexity farther back yet to 600 million years ago. The research found that the light sensitivity of the humble hydra is based on the same type of key opsin protein used in human vision.
We must believe not only that such an incredibly complex protein evolved somehow, but that it just happened to work splendidly in the as yet unforeseen incredible mammalian vision system. Imagine if a contraption your 5-year-old banged together in the basement just happened to work perfectly in a jet airliner. As the lead researcher commented:
This work picks up on earlier studies of the hydra in my lab, and continues to challenge the misunderstanding that evolution represents a ladder-like march of progress, with humans at the pinnacle. Instead, it illustrates how all organisms -- humans included -- are a complex mix of ancient and new characteristics.
It was all just a misunderstanding--now we understand. But with each new surprise, evolution becomes less likely and more complex.
