Tiger skulls dating back 90, 80 and 78 million years, as well as to other periods, have been unearthed from various sites. The tiger skull illustrated here is 76 million years old. All these fossils, unearthed at very different times, are identical to present-day tigers. Not one shows any changes, and there is no evidence to suggest that any one ever evolved in any way. None is any more or less developed than any other. This species is exactly the same today as it was millions of years in the past.
