New research led by the University of Leicester has overturned a long-standing theory on how vertebrates evolved their eyes by identifying remarkable details of the retina in the eyes of 300 million year-old lamprey and hagfish fossils.
The study, published in the journal Proceedings of the Royal Society B, led by Professor Sarah Gabbott from the University of Leicester Department of Geology, shows that fossil hagfish eyes were well-developed, indicating that the ancient animal could see, whereas their living counterparts are completely blind after millions of years of eye degeneration — a kind of reverse evolution.
No problem. It is called devolution.
But now the fun starts:
The eye is a complex structure and must have evolved through small step-by-step changes but these are not recorded in living animals and until now it was thought that these anatomical details could not be preserved in fossils.More.

The eye absolutely did not evolve by small step-by-step changes. This study only shows how the eye can devolve.
Darwinism = millstone on public payroll.
