However, the nice chart showing the different epochs in history along with the corresponding plants and animals is, itself, flawed. No place on earth contains every level. In fact, the levels are not even in the same order in different locations, and levels are even skipped. The age and placement of the levels was determined from the fossil record, whose age was determined from the levels. Very circular thinking.
Eyes cause major evolutionary chaos.
Without the complete structure, they are useless. However, in the geologic record, eyes suddenly appear. There is no precedent for them. Darwin said the eye structure caused concern for which he had no answer. A fact of science is that nothing living can arise by itself, but that's exactly what the evolutionary theory proposes.
