Malherne was nodding eagerly. "In connection with that, why is it that an insect goes along in its development, just like a common worm, until it reaches a certain size and age. Then it builds itself a cocoon or chrysalis, becomes a pupa, and starts a sort of 'prenatal' development all over again, but this time emerging as a full-fledged insect? Seems like they've been given a second crack at development which the other forms of life didn't get."
"That is substantially correct," agreed Zor Ala. "And we of the future have suspected that a higher type of life from somewhere has intervened in the development of life on Earth, and has experimentally given a boost to one branch of Earth-life by showing it how to re-encyst in a secondary 'egg' as a pupa, and thus continue its progress toward a higher evolutionary form before it finally emerges as an adult type."
"Whew!" Malherne ejaculated. "Whoever or whatever did that must really have been supermen!"
Zor Ala smiled. "At least," he agreed.
Malherne was struck with a sudden inspiration. "Look, would it be possible that the Kralons had something to do with the disappearance of the Dinosaurs during the latter part of the Mesozoic?—I understand, of course," he added hastily, "that this period where we find ourselves is around 100 million years before the time when the dinosaurs met their Waterloo. However, isn't it possible that descendants of the Kralons could have retained sufficient intellectual development to have been a serious threat to the existence of the 'saurs'?"
Zor Ala shook his head. "I'm afraid your theory won't stand up," he said. "For the Kralon race apparently only existed for a few million years, disappearing from the surface of the Earth around the end of the Carboniferous period.
"Thus the Kralons must have died out very nearly 100 million years before the dinosaurs' catastrophe, and the giant insects were apparently supplanted by only small, unintelligent prototypes without their size or intellectual vigor. No, there is almost certainly some other reason for the disappearance of the huge reptiles."
Malherne came to his feet suddenly. "Here I am discussing fantastic and fanciful theories, when four of my companions are somewhere in that hive of monsters! I've got to help them!"
"Calm down," Zor Ala soothed. "You would do them far more harm than good, now that the Kralons are watching for you. The best thing to do is to stay here and let them work out their own salvation as best they can. I know it sounds rather calloused, but any interference on your part now will certainly not be helpful."
"But I can't just sit here!" objected Malherne.
