The chance that higher life forms might have emerged through evolutionary processes is comparable with the chance that a tornado sweeping through a junk yard might assemble a Boeing 747 from the material therein. Fred Hoyle
The Law of Accelerating Returns: As order exponentially increases, time exponentially speeds up (that is, the time interval between salient events grows shorter as time passes). The Law... applies specifically to evolutionary processes. Ray Kurzweil
Moreover, the concern of some that moving DNA among species would breach customary breeding barriers and have profound effects on natural evolutionary processes has substantially disappeared as the science revealed that such exchanges occur in nature. Paul Berg
