The Year's Best Science Fiction, Vol. 20

Townsfolk gathered: bent matriarchs, robust matrons, slim girls and boys, even a few adult men. All were grey-brown, except the very old, who had turned white.

In general, people looked like their relatives; and everyone knew that family traits existed. Why else select breeding partners with so much care? There must be two tendencies within people, one toward similarity, the other toward difference. The same must also be true of animals. Domestic sulin came in different colors; by breeding, people had brought out variations that must have been in the wild animals, though never visible, except in freaks. She crouched in the shadows at the back of the merchants’ tent, barely noticing the commerce in front of her, thinking difficult thoughts.

Nowadays, geneticists tell us that the variation among people was caused by drift in isolated populations, combined with the tendency of all people to modify and improve anything they can get their hands on. We have bred ourselves like sulin to fit in different environments and to meet different ideas of beauty.

But how could Haik know this much about the history of life? How could she know that wild animals were more varied than she had observed? There are wild sulin in the far northern islands as thick furred and white as the local people. There is a rare, almost extinct kind of wild sulin on the third continent, which is black and entirely scaly, except for a ridge of rust-brown fur along its back. She, having traveled on only one continent, was hypothesizing in the absence of adequate data. In spite of this, she caught a glimpse of how inheritance works.

How likely is this? Could a person like Haik, living in a far-back era, come so near the idea of genes?

Our ancestors were not fools! They were farmers and hunters, who observed animals closely; and they achieved technological advances-the creation through breeding of the plants that feed us and the animals we still use, though no longer exclusively, for work and travel-which we have not yet equaled, except possibly by going into space.

In addition to the usual knowledge about inheritance, Haik had the ideas she’d gained from fossils. Other folk knew that certain plants and animals could be changed by breeding; and that families had traits that could be transmitted, either for good or bad. But most life seemed immutable. Wild animals were the same from generation to generation. So were the plants of forest and plain. The Goddess liked the world to stay put, as far as most people could see. Haik knew otherwise.

Dapple came after her, saying, “We need help in setting up our stage.”

That evening, in the long summer twilight, the actors performed the pesha comedy. Dapple had to make a speech beforehand, explaining what a pesha was, since they were far inland now. But the town folk knew about sulin, tli, and penises; and the play went well, as had the trading of the merchants. The next day they continued west.

Haik traveled with Dapple all summer. She learned to make masks by soaking paper in glue, then applying it in layers to a wooden mask frame.

“Nothing we carry is more valuable,” said the costume maker, holding a thick white sheet of paper. “Use this with respect! No other material is as light and easy to shape. But the cost, Haik, the cost!”

The bitalin continued to fascinate her: living animals as unfamiliar as the fossils in her cliffs! Her first mask was a bital. When it was dry, she painted the face tan, the six horns shiny black. The skin inside the flaring nostrils was red, as was the tongue protruding from the open mouth.

Dapple wrote a play about a solid and reliable bital cow, who lost her milk to a conniving tli. The tli was outwitted by other animals, friends of the bital. The play ended with Dapple as the cow, dancing among pots of her recovered milk, turned through the ingenuity of the tli into a new substance: long-lasting, delicious cheese. The play did well in towns of the western plains. By now they were in a region where the ocean was a rumor, only half-believed; but bitalin were known and loved.

Watching Dapple’s performance, Haik asked herself another question. If there was a hand inside the pesha’s flipper, could there be another hand in the bital’s calloused, two-toed foot? Did every living thing contain another living thing within it, like Dapple in the bital costume?

What an idea!

The caravan turned east when a plant called fire-in-autumn turned color. Unknown in Tulwar, it was common on the plain, though Haik had not noticed it till now. At first, there were only a few bright dots like drops of blood fallen on a pale brown carpet. These were enough to make the merchants change direction. Day by day, the color became more evident, spreading in lines. (The plant grew through sending out runners.) Finally, the plain was crisscrossed with scarlet. At times, the caravan traveled through long, broad patches of the plant, tsina and bitalin belly-deep in redness, as if they were fording rivers of blood or fire.
