Species of plants that exist for millions of years without undergoing any changes are a major blow to the theory of evolution. This fossil willow leaf, 54 to 37 million years old, has remained unchanged despite the passage of millions of years. The willow leaves of our day are the same as those that lived 54-37 million years ago.
