The seed fern fossil pictured is about 308 million years old, and it challenges evolution with its structure, unchanged for hundreds of millions of years. If the claims that living species develop by constantly changing were true, then during the hundreds of millions of years, ferns should have evolved into trees and germ cells had to change and develop totally different structures. But despite those 300 million years, no such change has been experienced and it will not happen in the future. Ferns of today are identical to those ferns that lived hundreds of millions of years ago. They have never experienced any evolutionary process, but were created with all their current features.
