Is there a basis for the 125% and 100% numbers? What if those "original" plants were 101% more efficient than later plants? Or 100.25% more? What if they started out only 99% efficient and gradually became more efficient, thus hitting that magic 125% mark much later on?
Maybe Kent Hovind is right, and there was a "canopy of ice" that surrounded the Earth, and therefore the plants had to be 250,000,000% more efficient!!!
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
