But many of his contemporaries disagreed. If evolution is always causing things to change, they asked, then how is it that two fossils from the same species, found in the same location, can look identical despite being 50 million years apart in age?\u003C\/p\u003E\r\n\r\n\u003Cp\u003EEverything changed in the past 40 years, when an explosion of evolutionary studies proved that evolution can and does occur rapidly \u2014 even from one generation to the next.
