None of their children had flowers. Only the two of them flowered, pollinated and seeded with regularity. Their seeds spread in a variety--and variety was the word, for in the first seeding she had packed as many variations as she could imagine. There was, in his opinion, too much emphasis on grasses after her own general style and too few creepers like himself. But that was a small detail. The original form did not last long in any case. Some of his seedlings had been enclosed by the rising marshes and were now more comfortable under water than above. A few wilder members even retained a measure of mobility and spent their lives floating from place to place. * * * * * He did not entirely approve of this. But, as the marshes grew under the constant rain and acquired an unpalatable saltiness so that they were virtually seas, he saw the sense of this development. He now covered, by himself and in proxy through his seeds, almost the entire land area of the planet. She extended just as far. They came to a working agreement to leave certain areas primarily for the grass-like progeny and others for his more treelike seedlings. The global view led them both to consider the same experiment. There were occasional worms and crablike creatures, minute bodies floating with his somewhat gipsy water-seedlings, but they and their own seeds were the only significant forms of life on their planet. "Shall we see what we can evolve?" he suggested. "I had that thought myself," she answered. "At least we know the end product. It seems unlikely, now, but man must have come from much this environment on Earth." "Very well. Where shall we start?" "I have some enterprising water-plants," he said diffidently. "_We_ have." It was an ambitious program. But, on the other hand, life on Earth had presumably also developed against all probabilities. Here on their planet they could provide continual intelligent guidance. They went out into their water-plants and sensed through their miles of sensory surfaces the most favorable areas of the planet. They encouraged the water-plants to breed, cross-breed and extend. They fed fractional parts of themselves to each other, loaded certain areas with nutrient life, encouraged mobility. Great continental areas rose and sank. Generation after generation was rapidly produced and as rapidly developed and died. The planet was littered with the remains of unsuccessful experiment. But, mainly by concentration on iron-rich diets and localizing their sight perceptions repeatedly in one particular part of their species, they produced plants which no longer responded to them. They had separate existence of their own. At last they managed to lure repeated generations out of the water and onto land.
