suitable number of samples for the next round of genetic augmentation.
In all, the process currently involved the introduction of seven distinct improvements to the basic human genotype. One such modification accelerated the formation of critical neural pathways, thus increasing intelligence. Another slight resequencing of the base pairs of a specific human gene had been found to substantially improve the efficiency of the lungs and respiratory systems, while the addition of a single new gene, adapted from one located in the DNA of the African gorilla, caused an increase in muscular density and resilience.
Now, after weeks of exacting effort, including the use of microscopic radioactive probes to confirm the presence of selected genes in various batches of modified eggs, only one last trial remained for this, the most recent crop of genetically engineered embryos. Careful [28] screening of hundreds of test samples had winnowed the selection down to a mere two dozen eggs, which had then been allowed to develop into the embryos currently awaiting Kaur’s final inspection. Of these candidates, only those she judged suitable would be implanted in the surrogate mothers who had agreed to carry the babies to term.
Only the best of the best of the best for our proud corps of moms-to-be, she mused, smiling. Many of the women involved were simply peasant women paid a generous sum for their cooperation and silence; since the surrogates made no genetic contribution to the children they carried, the project didn’t need to be too picky when it came to recruiting extra wombs. As long as the women stayed healthy and drug-free, and agreed to be monitored on a daily basis, they were good enough to serve as human incubators for the vastly superior beings gestating within them.
One of these days we really have to develop some workable artificial wombs, Kaur reflected. That would place yet one more crucial stage of human development under deliberate scientific control, not to mention sparing the project the burden of having to constantly recruit new surrogate mothers. She patted her abdomen, already bulging slightly beneath her voluminous white lab coat; in the meantime, she, along with nearly every other female member of Chrysalis, was glad to volunteer her own body as a biological petri dish in which the future of humanity was growing day by day.
She removed a cell sample from Subject #CHS-453-X and inspected it through the electron microscope, paying particular attention to the chromosomes as they paired off during cell division. Something didn’t look quite right about one pair, so, frowning, she increased the magnification. Through the lens of the microscope, the paired chromosomes looked like segmented black worms joined at their midsections so that each pair seemed to form a squiggly X shape. Except for one pair, that is. To Kaur’s chagrin, she saw that a piece of one chromosome seemed to have broken off and reattached itself to the wrong arm of the X, producing a distinctly lopsided and unsymmetrical set of chromosomes.
“Good heavens,” she said in Punjabi. How on Earth did that get [29] through the screening process? Lifting her face from the microscope, she used a grease pencil to mark the embryo in question for immediate incineration. Probably just a random mutation, she surmised, of the sort that spontaneously occurred every now and then. Oh well; if nothing else, catching an aberration like this one justified the long hours she put in giving the embryos a final checkup.
Thankfully, the next cell sample, from #CHS-454-X, showed no apparent defects, while the fetus itself appeared to be developing normally. Peering at the tiny speck of pink protoplasm, she couldn’t help marveling at the exquisite machinery tucked away in the nucleus of every cell in the fetus: nearly two meters of stringy nucleic acids capable of producing an individual who might someday change the world.
Just like its older brothers and sisters.
