The pattern was very much as had been conjectured for many years on Earth, except that ‘until 2028 it had all been assumed to have taken place on the wrong planet, or at least the fossils discovered from the pre-flfty-thousand-less-a-bit years B.C. period had been attributed to the wrong hominid family. But there was a completely unexpected phase that had never appeared in the story put together by the anthropologists on Earth: early in the man-ape era, the species had returned for a period to a semiaquatic environment, mainly as a consequence of not being equipped physically to deal with predators on land. Thus they had commenced the path that whales and other aquatic mammals had taken, but they reversed it and came out of the water again when their increasing intelligence provided them with other means of protecting themselves, which happened before any significant physical adaptations had developed. This phase accounted for their upright posture, loss of body hair, rudimentary webbing between thumb and index finger, the salt-excreting function of their tear ducts, and several other peculiarities that experts on Earth had been arguing about for years. Danchekker would have spent the rest of the week talking about that alone, but Hunt persuaded him to take it up again with Eesyan at some other time.
After that came the discovery of tools and fire, tribalization, and the sequence of evolving social order that led from primitive hunter-gatherer economies through agriculture and city-building to
the discovery of the sciences and the beginnings of industrialization. And there was something about this part of their history too that set them apart from terrestrial humans in Hunt’s eyes: the practical and realistic approach that the Lunarians had adopted to everything they did. They had exploited their resources and talents efficiently, without drifting off into fruitless reliance on superstitions and magic to solve their problems as had so many millennia of Earth people. For the early hunters, better weapons and greater skill decided success, not the whims of imaginary gods who needed to be placated. For the crop growers, better knowledge of plants, the land, and the elements improved yields; rituals and incantations did not, and were soon abandoned. And not very long afterward it was measurement, observation, and the powers of reason that uncovered the laws governing the universe and opened up new horizons for the harnessing of energy and the creation of wealth. As a result the Lunarian sciences and industries had mushroomed almost overnight in comparison with the halting, faltering groping toward enlightenment that had come later when the same general pattern repeated itself on Earth.
The scientists on Earth who had recovered the information on the Lunarians had pictured them as an incurably aggressive and warlike breed whose discoveries of advanced technology had inevitably spelled their eventual self-destruction. Hunt and the others now learned that this picture was not really accurate. There had been some feuding and fighting in the earlier periods of Lunarian history, it was true, but by the time of the early industrial period such things had become rare. A greater common cause had united the Minervan nations. Their scientists recognized the deteriorating conditions that were descending with the coming Ice Age, and the whole race embarked on a feverish development of the sciences that would enable them to move to a warmer planet in the centuries ahead. The astronomers of the time singled out Mars and Earth as the most promising candidates. The stakes were survival, and there were no resources to be squandered on internal conflicts, until. .
About two hundred years before the final, catastrophic war, something happened to change all that. Calazar explained, “It could have been a result of extreme genetic instabilities still inherent in the race. At about the time they had learned to harness steam and were just beginning to explore electricity, a superbreed
of Lunarians appeared quite suddenly and advanced a quantum leap ahead of anything else in existence anywhere on the planet. Exactly where or when they appeared we don’t know. Numerically they were few to begin with, but they spread and consolidated rapidly.”
“Was that when the planet started to polarize?” Heller asked.
“Yes,” Calazar replied. “The superbreed became the Lambians. They were totally ruthless. They militarized and formed a totalitarian regime that imposed itself by force on a large portion of the planet before the other nations could muster the strength to resist. Their aim was to gain control of Minerva’s industrial and technical capabilities totally and exclusively to guarantee their own move to Earth, which meant taking over the nations that had been pursuing that goal collectively. Submission would have meant extinction. The other nations had no choice but to unite, arm, and defend their security. They became the Cerians. The course was set irrevocably toward a struggle to the death between the two factions.”
