But the supersome-driven fetus continued to grow larger and larger in its artificial womb. We had expected it to stop on its own at some point: oh, a Forhilnor might stumble into life with a double-length chromosome; a human child might survive for a time having three chromosome twenty-ones. But this combination, this wild genetic concoction, this mishmash, was surely too much, surely pushed the limits of the possible too far. Most pregnancies — be they Wreed or Forhilnor or human — spontaneously abort early on as something goes wrong in the embryo’s development, usually before the mother is even aware that she’s pregnant.
But our fetus, our impossible triple hybrid, did not.
In all three species, ontogeny — the development of the fetus — seems to recapitulate phylogeny — the evolutionary history of that organism. Human embryos develop then discard gills, tails, and other apparent echoes of their evolutionary past.
This fetus was going through stages, too, changing its morphology. It was incredible — like watching the Cambrian explosion play out in front of my own eyes, a hundred different body plans tried and discarded. Radial symmetry, quadrilateral symmetry, bilateral symmetry. Spiracles and gills and lungs and other things none of us recognized. Tails and appendages unnamed, compound eyes and eyestalks, segmented bodies and contiguous ones.
No one had ever quite figured out what ontogeny apparently recapitulating phylogeny was all about, but it wasn’t a real replay of the organism’s evolutionary history — that was apparent since the forms didn’t match those found in the fossil record. But now its purpose seemed clear: DNA must contain an optimization routine, trying every variation that might be possible before selecting which set of adaptations to express. We were seeing not just terrestrial and Beta Hydrian and Delta Pavonian solutions, but also blendings of all three.
Finally, after four months, the fetus seemed to settle on a body plan, a fundamental architecture different from that of human or Forhilnor or Wreed. The fetus’s body consisted of a horseshoe-shaped tube, girdled by a hoop of material from which six limbs depended. There was an internal skeleton, visibly forming through the translucent material of the body, but it was made not of smooth bone but rather of bundles of braided material.
We gave the embryo a name. We called her Wibadal, the Forhilnor word for peace.
She was another child I would not live to see grow up.
But, like my own Ricky, I’m sure she would be adopted, cared for, nurtured, if not by the crew of the Merelcas, then by the vast, palmate blackness sprawling across the sky.
God was the programmer.
The laws of physics and the fundamental constants were the source code.
The universe was the application, running now for 13.9 billion years, leading up to this moment.
That the ability to transcend, to discard biology, came too soon in a race’s life was a bug, a flaw in the design, a complication never intended. But finally, with careful manipulation, the programmer had worked around that bug.
And Wibadal?
Wibadal was the output. The point of it all.
I wished her well.
It was the ancient progression, the engine that had always driven evolution. One life ends; another begins.
I went into cryofreeze again, passing the next eleven months with my body, and its degenerations, arrested. But when Wibadal’s gestation was finally complete, Hollus reawakened me for what, we both knew, would be the last time.
The Wreeds had announced that today would be the day; the child was now whole and would be removed from the artificial womb. “May she express the best in all of us,” said T’kna, the Wreed I’d first met by telepresence all those months — and all those centuries — ago.
Hollus bobbed her torso. “A” said one of her mouths, and “men” concluded the other.
I was groggy from the suspended animation, but I watched in fascination as Wibadal was decanted from the womb. She came into the universe crying, just as I had done, and just as all the billions who had gone before me had.
Hollus and I spent hours simply looking at her, a strange, bizarre form, already half as big as I was.
“I wonder what her life span will be,” I said to my Forhilnor friend; perhaps an odd question, but life spans were very much on my mind.
“Who” “knows?” she replied. “The lack of telomeres does not seem to be an impediment for her. Her cells could go on reproducing forever, and—”
She stopped.
“And they will,” she said after a few moments of reflection. “They will. That entity” — she gestured at the space-faring blackness centered on one of the wall-sized viewing screens — “survived through the last big crunch and big bang. Wibadal, I suspect, will survive though the next, becoming God to the universe that follows this one.”
It was a staggering notion, although perhaps Hollus was right. But I wouldn’t live long enough to know for sure.
Wibadal was behind a glass window in a specially built maternity ward with a single circular crib. I tapped on the glass, the way parents on my world had done millions of time before. I tapped, and I waved.
And Wibadal stirred, and waved a stubby, chubby appendage back at me. Maybe the current God had never acknowledged my presence — even when I’d come right up to him, he’d still been indifferent to me — but this god-to-be had noticed me, at least once, at least for a moment.
And, for that moment, I felt no pain.
But soon, the agony was back; it had been growing worse, and I had been growing weaker.
Time was running short.
I wrote a final, long letter to Ricky in case, by some miracle, he was still alive. Hollus transmitted it to Earth for me; it would reach there almost half a millennium hence. I told my son what I’d seen here and how much I loved him.
And then I asked Hollus for a last favor, a final kindness. I asked her for the sort of thing only a good friend could request of another. I asked her to help release me, to help me pass on. I’d brought only a few things with me from Earth, besides my cancer medication and pain pills. But I did bring a biochemistry text with enough information for the Merelcas’s doctor to synthesize something that would painlessly and swiftly end my life.
Hollus herself administered the injection, and she sat by my bed, holding my emaciated hand in one of hers, her bubblewrap skin the last thing I felt.
I told Hollus to write down my final words and transmit them back to Earth, as well, so that Ricky, or whoever was still there, would know what I’d said. As I mused before, perhaps he, or one of my great-to-the-nth grandchildren, might even put together a book about the first contact between an extraterrestrial and someone who, I suppose, was all too human.
I was surprised by what my last thoughts turned out to be. “You know,” I said to Hollus, her eyes weaving back and forth, “I remember when I first became fascinated with fossils.”
Hollus listened.
“I’d been at the beach,” I said, “playing with some rocks, and I was amazed to find a stone shell embedded in one of them. I’d found something then that I’d never even known I’d been looking for.” The pain was easing; everything was slipping away. I squeezed the Forhilnor’s hand. “I guess I’m a lucky man,” I said, feeling peace come over me. “It’s happened a second time.”
