In any case, argued Cuvier, drawing on specimens brought back by Napoleon’s savants from the ...French incursions into Egypt, the mummified forms of cats and birds and other organisms—beings that lived literally thousands of years ago—are absolutely identical forms living today. Where then is the evolution, the change, in all of this? If Lamarck be right, we should expect to see some change right before our eyes, and this we do not see. (Michael Ruse, The Evolution Wars, Rutgers University Press, 2000, p. 23.)
This admission by Michael Ruse emphasizes how living things have been known not to change ever since the idea of evolution began. The reality exhibited by the 64-million-year-old bear skull illustrated is that the species has never changed at any time.
