Plants have extremely complex structures, and it is impossible for them to have emerged through coincidental effects or for one species to have transformed into another, as evolutionists claim. Fossil record also reveals that different plants have emerged on Earth momentarily, with structures peculiar to them and that they had no evolutionary "ancestors" before them, as evolutionists claim. For instance this 320-million-year-old fossil fern indicates that these plants have not changed for hundreds of millions of years. Ferns in our day are no different from those that lived 320 million years ago. In the face of this fact, evolutionists can give no reasonable scientific answer.
