Fobo paused, then said, 'You must realize that most of this is speculative. It's based largely on what the very few human natives we've captured in the jungle have told us. However, we recently discovered some pictographs in a long-buried temple that gave us additional information. So we think our reconstruction of the history of the lalitha is valid.
'Oh, by the way, Jeannette didn't have to run away from us. After we'd learned all we could from her, we'd have returned her to her family. We told her we would, but she didn't believe us.'
A wog nurse came out of the operating room and said something to the empathist in a low voice.
Macneff walked by her and obviously tried to eavesdrop. But as the nurse was speaking in Ozagenian, which he did not understand, he continued pacing back and forth. Hal wondered why he, Hal, had not been dragged away at once, why the priest had waited to hear Fobo out. Then, a flash of insight told Hal that Macneff wanted him to hear all about Jeannette and realize the enormity of his deeds.
The nurse went back into the operating room. The Archurielite said loudly, 'Is the beast of the fields dead yet?'
Hal shook as if he had been struck when he heard the word dead. But Fobo ignored the priest.
He spoke to Hal. 'Your larv – that is, your children, have been removed. They are in an incubator. They are...' he hesitated - 'eating well. They will live.'
Hal knew from his tone that it was no use asking about the mother.
Big tears rolled from Fobo's round blue eyes.
'You won't understand what has happened, Hal, unless you comprehend the lalitha's unique method of reproduction. Three things the lalitha needs to reproduce. One thing must precede the other two. That primary event is to be infected at the age of puberty by another adult lalitha. This infection is needed to transmit genes.'
'Genes?' said Hal. Even in his shock, he could feel interest and amazement at what Fobo was telling him.
'Yes. Since lalitha receive no genes from the human males, they must exchange hereditary material between each other. Yet – they must use man as a means.
'Allow and permit me to elucidate. An adult lalitha has three so-called banks of genes. Two are duplicates of each other's chromosomal stuff.
'The third, I will explain in a moment.
'A lalitha's uterus contains ova, the genes of which are duplicated in the bodies of microscopic wrigglers formed in the giant salivary glands in a lalitha's mouth. These wrigglers – salivary ova – are continually released by the adult.
'The adult lalitha pass genes by means of these invisible creatures; they infect each other as if the carriers of heredity were diseases. They cannot escape it; a kiss, a sneeze, a touch, will do it.
'Preadolescent lalitha, however, seem to have a natural immunity against being infected by these wrigglers.
'The adult lalitha, once infected, then builds up antibodies against reception of salivary ova from a second lalitha.
'Meanwhile, the first wrigglers she is exposed to have made their way through the bloodstream, the intestinal tract, the skin, boring, floating, until they arrive at the uterus of the host.
'There, the salivary ovum unites with the uterine ovum. Fusion of the two produces a zygote. At this point, fertilization is suspended. True, all genetic data needed to produce a new lalitha is provided. All except the genes for the specific features of the face of the baby. This data will be given by the male human lover of the lalitha. Not, however, until the conjunction of two more events.
'These two must occur simultaneously. One is excitation by orgasm. The other is stimulation of the photo-kinetic nerves. One cannot take place without the other. Neither can the last two come about unless the first happens. Apparently, fusion of the two ova causes a chemical change in the lalitha which then makes her capable of orgasm and fully develops the photokinetic nerves.'
Fobo paused and cocked his head as if he were listening for something outside. Hal, who knew from familiarity with the wogs what their facial expressions meant, felt that Fobo was waiting for something important to happen. Very important. And, whatever it was, it involved the Earthmen.
Suddenly, he thrilled to the knowledge that he was on the wogs' side! He was no longer an Earthman, or, at least, not a Haijac.
'Are you sufficiently confused?' said Fobo.
'Sufficiently,' Hal replied. 'For instance, I have never heard of the photokinetic nerves.'
'The photokinetic nerves are the exclusive property of the lalitha. They run from the retina of the eye, along with the optic nerves, to the brain. But the photokinetic nerves descend the spinal column and leave its base to enter the uterus. The uterus is not that of the human female. Do not even compare them. You might say that the lalitha uterus is the darkroom of the womb. Where the photograph of the father's face is biologically developed. And, in a manner of speaking, attached to the daughters' faces.
'You must have noticed during your intercourse with her, for I'm sure she insisted you keep your eyes open, that her pupils contracted to a pinpoint. That contraction was an involuntary reflex which would narrow her field of vision to your face. Why? So the photokinetic nerves could receive data from only your face. Thus, the information about the specific color of your hair could be passed on to the bank of photogenes. We don't know the exact manner in which the photokinetic nerves transmit this data. But they do it.
'Your hair is auburn. Somehow, this information becomes known to the bank. The bank then rejects the other genes controlling other colors of hair. The 'auburn' gene is duplicated and attached to the zygote's genetic makeup. And so with the other genes that fix the other features of the face-to-be. The shape of the nose-modified to be feminine-is selected by choosing the correct combination of genes in the bank. This is duplicated, and the duplicates are then incorporated into the zygote–'
'You hear that?' shouted Macneff in an exultant voice. 'You have begat larvae! Monsters of an unholy unreal union! Insect children! And they will have your face as witness of this revolting carnality–'
'Of course, I am no connoisseur of human features, Fobo interrupted. 'But the young man's strike me as vigorous and handsome. In a human way, you understand.'
He turned to Hal. 'Now you see why Jeannette desired light. And why she pretended alcoholism. As long as she had enough liquor before copulation, the photokinetic nerve – very susceptible to alcohol – would be anesthetized. Thus, orgasm but no pregnancy. No death from the life within her. But when you diluted the beetlejuice with Easyglow... unknowing, of course–'
Macneff burst into a high-pitched laughter. 'What irony! Truly it has been said that the wages of unrealism are death!'
Fobo spoke loudly. 'Go ahead, Hal. Cry, if you like. You'll feel better. You can't, eh? I wish you could.
'Very well, I continue. The lalitha, no matter how human she looks, cannot escape her arthropod heritage. The nymphs that develop from the larvae can easily pass for babies, but it would pain you to see the larvae themselves. Though they are not any uglier than a five months' human embryo. Not to me, anyway.
'It is a sad thing that the lalitha mother must die. Hundreds of millions of years ago, when a primitive pseudoarthropod was ready to hatch the eggs in her womb, a hormone was released in her body. It calcified the skin and turned her into a womb-tomb. She became a shell. Her larvae ate the organs and the bones, which were softened by the draining away of their calcium. When the young had fulfilled the function of the larva, which is to eat and grow, they rested and became nymphs. Then they broke the shell in its weak place in the belly.
'That weak point is the navel. It alone does not calcify with the epidermis but remains soft. By the time the nymphs are ready to come out, the soft flesh of the navel has decayed. Its dissolution lets loose a chemical which decalcifies an area that takes in most of the abdomen. The nymphs, though weak as human babies and much smaller, are activated by instinct to kick out the thin and brittle covering.
'You must understand, Hal, that the navel itself is both functional and mimetic. Since the larvae are not connected to the mother by an umbilical cord, they would have no navel. But they grow an excrescence that resembles one.
'The breasts of the adult also have two functions. Like the human female's, they are both sexual and reproductive. They never produce milk, of course, but they are glands. At the time the larvae are ready to hatch from the eggs, the breasts act as two powerful pumps of the hormone which carries out the hardening of the skin.
'Nothing wasted, you see – Nature's economy. The things that enable her to survive in human society also carry out the death process.'
'I can understand the need for photogenes in the humanoid stage of evolution,' Hal said. 'But when the lalitha were in the animal stage of evolution, why should they need to reproduce the characteristics of the father's face? There isn't much difference between the face of a male animal and a female animal of the same species.'
'I do not know,' said Fobo. 'Perhaps, the prehuman lalitha did not utilize the photokinetic nerves. Perhaps, those nerves are an evolutionary adaptation of an existing structure which had a different function. Or a vestigial function. There is some evidence that photokinesis was the means by which the lalitha changed her body to conform with the change in the human body as it passed up the evolutionary ladder. It seems reasonable to suppose that the lalitha needed such a biological device. If the photokinetic nerves were not involved, some other organ may have been. It is unfortunate that by the time we were advanced enough to scientifically study the lalitha, we had no specimens available. Finding Jeannette was pure luck. We did discover in her several organs whose functions remain a mystery to us. We need many of her kind for fruitful research.'
