Does Evolution Theory has an age limit for a certain specie to evolve into something new?
There is no time frame for things to evolve, indeed some things seems to evolve remarkably rapidly, some extremely slowly. It all depends on the selection pressures, which are the rules that govern evolution itself. During the earth’s history different areas have undergone different changes and so species have experienced changing selection pressures. If these selection pressures are extremely fast often the species can’t keep up and die out. For instance if you suppose the dinosaurs were wiped out by the dust cloud produced by an asteroid impact, it was because their conditions changed so quickly there was no hope of them evolving into species that could deal with the new environment. If conditions shift rapidly but not too rapidly, often a speciation event or at least a new morph of a species can occur very quickly. For instance antibiotic resistant bacteria can crop up in only a matter of days or weeks from a population that was previously not resistant. On a slightly more macrologi
