A major problem for Neo-Darwinism is the complete lack of evidence for plant evolution in the fossil record. As a whole, the fossil evidence of prehistoric plants is actually very good, yet no convincing transitional forms have been discovered in the abundant plant fossil record. This fact has been recognized by both creationists and evolutionists as providing strong evidence for abrupt appearance theory. If macroevolution were true, some evidence of plant evolution should exist in the abundant plant fossil record. Instead, what is found are many examples of modern plants, variations of modern plants, or extinct plants that require still more transitional forms.
Flowering plants nowadays dominate terrestrial ecosystems and, as a major food source, are of outstanding importance for mankind.
