The fossil pictured here, the skull of a hyena between 23 and 5 million years old, corroborates this admission. This fossil proves that hyenas have always existed as hyenas and refutes the theory of evolution. The fact that hyenas living tens of millions of years ago are no different from today"s members of the species is evidence for the invalidity of evolution. If the evolutionists" claims were true, hyenas should have turned into much different mammals by this time. But no such thing has happened.
