For example, with the origin of birds, there are two main theories [argued between evolutionists]: that birds evolved ‘ground up’ from running dinosaurs (the cursorial theory), and that they evolved ‘trees-down’ from small reptiles (the arboreal theory). Both sides produce devastating arguments against the other side. The evidence indicates that the critics are both right—birds did not evolve either from running dinos or from tree-living mini-crocodiles. In fact, birds did not evolve from non-birds at all!
