OBSERVATION ON CREATION VS EVOLUTION

 WHY DID T-REX HAVE TINY USELESS ARMS?
 If dinosaurs ( some dinosaurs ) evolved into birds, then T-Rex is not an ancestor of the parachete for it's "wings" were evolving shorter, NOT longer.  The answer is that the relatively small T-Rex arms have nothing to do with evolution, but rather it is due to disproportional growth of limbs.   The hatchling starts life as a 4 legged creature.  It could not have ripped raw meat from a kill by shifting it's weight as the adults did.  It had to brace the tough meat with it's front legs and pull off a bite.  The baby needed 4 legs to clammer over fallen trees and terrain.
When T-Rex grew to the size of a Raptor, it would need not front legs, but now it needed arms like the Raptor to compete with the Raptor and take down prey without just the jaws and mass of the adult.
In summary, the rear legs grew fast and the front legs grew slow.  There never was an adult T-Rex ancestor ( missing link ) with usably sized arms or with 4 legs.
