The eggs that have been laid hatch into a second generation which continue the flight farther north, taking as many as four generations to fly as far north as Ontario, Canada. The last generation does not develop its reproductive organs, and therefore begins its autumn migration back to Mexico. When the female lays her last egg, her process of dying begins, so those in the 5th generation sustain the greatest longevity. The monarch butterflies are the only insects on Earth to migrate annually over continental distances, and it is estimated that over 300 million of these fantastic creatures migrate to Mexico every year. Their navigational systems are extremely complex to direct them as far as 3000 miles to a wintering site they have never seen, and then to guide them in the spring on their northeast travel to different parts of the U.S. and Canada.
Evolutionism provides no believable explanation for such remarkable abilities.
The design argument in analogy form is empirical or a posteriori . When one examines the life and migration cycles of the monarch butterfly, it is easy to see design features which point back to a Designer. There is inexorable order in the repeatable progress of developmental stages. An incredible plan unfolds in the transforming pupal stage, through larval disintegration and reintegration to the miracle and beauty of a winged insect. Simplicity in feeding, complexity in navigation, beauty in coloration all speak of incredibly packed information in its genetic message.
