How does one take such a pronouncement? Jude fell apart. Bill Raby’s consciousness wept inside, while I… well, I just got angry. ‘Remove the tumor,’ I demanded.
‘It’s not a tumor,’ the resident surgeon said. ‘Your brain is swelling. Intracranial pressure has risen from 210 mm to 270, and it’s still climbing. There simply isn’t enough room in your skull to allow for any more growth.’
Within hours, I slipped into a coma.
The Homo sapiens brain is an incredibly unique organ, its electrochemical design quite different from the rest of the body. It is shielded from direct contact with blood, and contains a hundred billion working cells called neurons, which make over a thousand trillion connections. The organ may be the most complex computer in the universe, yet, despite all our God-given intelligence, our species was still only capable of using roughly 10 percent of its brain, lacking the genetic programming to do otherwise.
The human brain also consists of several unique layers that reflect the gradual progression of our evolution. Rather than discard the antiquated layers, nature had simply built upon them, preserving our evolutionary history- and perhaps our tendency toward violence.
The oldest and deepest of these layers, dubbed the ‘neural chassis,’ consists of the midbrain, brain stem (medulla and pons) and the spinal cord, and controls our basic life functions, such as our heart beat, blood circulation, and respiration. Surrounding this layer is the R-complex, nicknamed the ‘reptilian brain,’ as it controls our aggressive behavior, social hierarchy, and territoriality. It consists of our globus pallidus, corpus striatum, and olfactostriatum.
Surrounding the R-complex is the limbic system, a layer developed during our evolution as mammals. Comprising the thalamus, hypothalamus, amygdala, pituitary, and hippocampus, it controls social behavior, emotions, and complex relations required for living in cohesive groups.
The outermost layer of the brain is a tablecloth-sized sheet folded like a parachute. It controls reason, spatial perception, and language. Known as the neocortex, it is divided by anatomists into the frontal, parietal, temporal, and occipital lobes. While the outer layers of other animal brains are smooth, ours is grooved, increasing the surface area of the cerebral cortex.
I bore you with these anatomical facts because, as I lay in bed in my coma, I dreamed that I was actually walking through this outer maze of gray matter, lost in the canyons of my neocortex. Reaching a precipice, I looked down, staring into the dark recesses of human existence.
And I saw everything.
The birth of our universe.
The formation of galaxies.
The evolution of life on ancient Earth.
From insectivores to primates. From early hominid to modern man.
And suddenly, as if a curtain had been lifted, I understood.
Futurists in my time had defined three categories of evolution for human civilization. Type-I civilizations were those that master all forms of our home world’s energy resources. This includes everything from mining the oceans to tapping into the planet’s core, to modifying the weather. A Type-I civilization is mature enough to rise above petty conflicts of politics, race, religion, and culture to develop a unified planetary economy. While still susceptible to certain environmental and cosmic catastrophes, Type-I civilizations have begun the process leading to the colonization of nearby planets.
The next step up the evolutionary ladder are Type-II civilizations, which harness energy solely by way of their suns. They have colonized other planets and have begun the exploration and possible colonization of nearby solar systems. Able to manipulate their environment, they will no longer be in danger of facing extinction by glaciation or asteroid impact, but will still be vulnerable to supernovas, whose eruptions could irradiate nearby planets.
Type-III civilizations are the pinnacle of advanced societies. They have exhausted the energy output of their suns and must reach out to other star systems throughout the galaxy. Their starships approach the speed of light, and perhaps, have even mastered ‘Planck energy,’ the energy necessary to violate the very fabric of space and time.
In other words, Jacob, they can manipulate wormholes.
When I left Earth in 2012, our species was still a struggling Type-0 civilization. Our people were hopelessly divided, enmeshed in petty conflicts of equality, religion, and politics. Our technologies focused on making war, and we very nearly destroyed ourselves in our quest of ego and self. Type-0 civilizations are always prone to disasters, whether self-induced, or, as our predecessors learned, through the fury of Mother Nature.
What scientists had left out of the equation was hominid evolution. Homo sapiens was not the last stop up the evolutionary ladder; it was merely the beginning… and love was our key to survival.
As this knowledge was imparted to me, I found myself staring at my own genome. The spiraling ladder of DNA was changing, continuing an incredible metamorphosis that had begun the moment the first drops of alien water had passed across my lips.
And though I was dreaming, I knew the vision was real, that I was actually changing, evolving into something more efficient-something superior. Another layer of brain tissue, a hypercortex, was growing over my neocortex.
I was becoming… Transhuman.
The transhumanist school first surfaced at the turn of the twentieth century when science fiction gave rise to serious futurism. The term ‘transhuman’ implies our species as being transitional, that Homo sapiens does not represent the end of our evolution but rather its true beginning. Through bioscience breakthroughs and technological advances in nanoscale engineering that enabled telomeric augmentation, proliferated nanoimplants, genomic editing, and mitochondrial genetic preservation, individual humans could prepare themselves as transhumans to reach our ultimate goal as a species: Posthumanism.
A posthuman was imagined to be an augmented super-brained person no longer merely human. It was believed that posthumans could end up as completely synthetic organisms, living far beyond the human body’s limitations-or as some imagined, as exobody consciousness, programmed within some futuristic biochemical computer.
As I watched my genome evolve, my hallucination instructed me. It showed me how my brain was growing. Taught me how to program my own neurological pathways simply by using streams of conscious thought. My dream guided me toward understanding how my biological processes worked and how they could be manipulated.
More than seven full months would pass before I emerged from my coma. When I awoke, I learned I had evolved into a different Homo sapiens subspecies.
It began with my appearance, which was bizarre, bordering on the grotesque. My skull had completely deformed, elongating to accommodate the increased mass of my brain. My body had enlarged as well, to better nourish the brain. My muscles were stronger, not only able to lift heavier weights, but they could fire faster, as if Bill Raby’s neural connections had doubled in speed.
There was a new clarity to my thought process. My mind could suddenly recall obscure documents I had read years earlier-word for word. My brain possessed an eidetic memory, but with highly expanded associativity, cataloging key concepts, drawing upon oceans of information in a millisecond of preconscious thought.
The entire colony was undergoing an identical metamorphosis.
As Jude was still in her coma, I decided to leave the ward, my new intellect determined to reveal New Eden’s secrets. My first destination was a massive structure, standing seventy-eight stories tall, encompassing a thousand acres. What drew me to this alien facility was its exterior lead gray surface, adorned in ever-changing patterns of lines and glyphs, which radiated the colors of the spectrum.
An imposing thirty-foot arch delineated the grand entry. Approaching the sealed hatch, I closed my eyes and focused my thoughts inward, imagining the doors unsealing to allow me entry.
Immediately, a strange buzzing sensation overcame me, as if my brain was expelling volts of electricity. I fell to my knees, overcome by vertigo.
When the buzzing stopped, I opened my eyes.
The portal had unsealed.
