Microstory 1647: Biological Soulmates

There are a few different universes that have the same, or similar, rules about this sort of thing, but I’ll only talk about the one. Evolution is a pretty simple concept when you really get down to it. A mutation occurs in an individual specimen. If it doesn’t prevent that individual from surviving, that trait is more likely to be passed down to the next generation. It doesn’t matter if the trait is good or bad. It only has to be good enough to survive in the bloodline (i.e. to not prevent that bloodline from continuing). There are some evolutionary traits that shouldn’t exist, and some have suggested that this is evidence that some higher power is up there, making decisions. I don’t think that’s true, but the universe today is crazy enough to make me doubt my faith in science. When two members of the opposite sex have intercourse for the first time, they will be forever bonded to each other, on multiple levels. They will release chemicals that not only prevent them from producing children with different partners, but also from even having sex with other people. If they try, it will hurt. Two sexually incompatible partners who attempt to join will both be flooded with painful chemicals that flow throughout their bodies, and don’t stop until the sex stops. Other universes have similar compatibility limitations, but don’t take it this far. They can still choose multiple partners, it’s just that they can only produce offspring with their so-called soulmates. Why did evolution come up with this? What could possibly drive such a ridiculous series of traits? Well, the obvious answer is that forcing a single soulmate encourages the family dynamic, which supports the stable upbringing of a child. But is that enough? Apparently so, but it doesn’t make much sense; not according to evolutionary biology.

As I was saying, an evolutionary trait will persist down the bloodline if it doesn’t prevent the bloodline itself from persisting. This should not have happened in this case. The first sign of this incompatibility trait should have been stopped shortly after the mutation appeared. Most animals copulate with multiple partners. They’re all just trying to pass their genetic information onto their descendants. It’s the number one biological imperative. Restricting an individual to one lifelong partner is fine for humans, and a few other animals, but only when it’s a choice, or rather, only when it’s not the only avenue. Most of the time, monogamy is not a very good survival trait, and it doesn’t always support the biological imperative. Sure, perhaps a child is better off being raised consistently by two parents, but evolution isn’t about the survival of an individual. It’s about the continuity of the species as a whole, and math tells us that having a lot of children has been the default tactic for most of evolutionary history. Monogamy only works well when you have options, not when it’s unavoidable. What if the father dies after only producing one child? It’s up to that child to continue the bloodline, and if it also dies, then it’s over. It’s much better if the mother can go find another partner, and give their first child half-siblings. While the original father’s genetic traits may end, at least hers has a chance to go on. All this being said, the arguments against this sort of thing don’t seem to have stopped it from happening to the humans who evolved in this universe, so there must be some significant benefit that I’m not seeing. Despite the bizarre constraints, the residents have been quite successful, and even prosperous.

Microstory 995: Panda Neglect

This is a quite unpopular one, and is probably too negative for this list, and I realize that. You may be asking, why would you not want to save the pandas? Well, I’m not suggesting we go out and murder a bunch of animals, but we should certainly stop wasting all of our resources on protecting them. 99% of animals that have ever lived on this planet have gone extinct, a great many of them dying out in the third mass extinction event. To be sure, humans are the cause of a lot of death, but we can’t be blamed for most of this. When it comes to evolution, there are three general outcomes. The first is that a mutation can become a positive genetic trait, leading to an advantage which allows that species to survive. The second is a neutral trait, which doesn’t have that much effect in the long run. It often leads to subspecies, because the individuals who do not possess the trait are still doing fine. The third is a negative trait, and will lead to death. If it doesn’t help the species to survive, then the mutated creature will likely die before passing on their genes, and the rest of the population won’t have to worry about it. Then you have the panda. Pandas separated from the rest of the bear family tree about three million years ago, likely due to environmental restrictions. While they were originally well-designed for an omnivorous diet, scientists believe there wasn’t enough meat around, which essentially forced them to subsist on what was available. For as little nutrition as bamboo provides, it certainly grows quickly, and would have a hard time going extinct itself. The problem is that the panda doesn’t care how quickly bamboo grows. It prefers to eat the sprouts, which are about half as nutritious, which means a panda has to eat twice as much; ultimately half of their own body weight. Can you imagine eating *cough* thirty-six kilograms *cough* of food a day? The biggest argument against panda conservation is how much we’re wasting on breeding them when they’re better off doing it in the wild. We’ve all heard how dumb these animals are, and how bad they are at sex, but the reason they’ve survived this long is they’re actually not all that bad at it in the wild. They’re only bad at it in captivity, because....well, wouldn’t you be? If we want to save the pandas, then we should leave them be. The reason we have to work so hard protecting other species, like elephants, is because other forces are working against us, but there’s not a huge market for panda meat. That’s right, all your efforts to save them are actually harming them. We can’t change what they choose to eat, but we can choose to ignore them. Set the pandas free, and leave them alone. If they die out, then that makes me a saaaad panda. But also not, because I don’t care that much; they mostly did it to themselves.

Microstory 918: Posthumanism

If you redirect your attention to this post, and this post, you’ll see that I’ve already spoken on the subject of transhumanism. If you’ve already read those stories, and don’t feel like going back, or if you just don’t want to, here’s the gist of it. Humans are weak and fragile creatures, just like most other creatures. There are too many things that can destroy life. Even the most ferocious beasts, and the hardiest of extremophiles are susceptible to multiple dangers. A lot of people have this belief that evolution is heading towards some level of perfection, but that is not how it works. A specimen develops a trait as a random mutation, and if it’s a bad mutation—one that hinders their ability to survive—then they simply won’t live long enough to procreate. If it does happen to help, then they’ll pass those genes on to their offspring. The reason humans have hair still, even though we’ve learned to fashion clothing, build houses, and invent central heating, is because there’s no one to change it. Having hair isn’t a problem for us. At best, our descendants might evolve out of it due to sexual selection, if mates begin to favor less hair enough, but that’s so unlikely, because for humans, it takes all kinds. The point of this is that evolution isn’t going to give us gills or wings, because we don’t live in environments that would require them. Winged humans wouldn’t have an advantage over non-winged humans, because we do just fine right here on the ground. If the floor suddenly literally turned to lava, we would just die out by the time our physiology changed to accommodate our new conditions. If you want wings, then you’re going to have to have them implanted. You’re going to need two things to do this, though. One, superhuman pecs. Seriously, look at any bird. There’s a reason the breast contains so much more meat the rest of any poultry. Two, you’re going to need to live in the future, because we can’t attach wings to people yet. We can’t implant gills, or artificial eyes, or neural interface chips. But we will be able to. One day. That’s what posthumanism is all about, and posthumanism is what I’m all about. Like I said, humans are weak, and I am no exception. I have allergies; my hands are in a permanent state of pain. I wear glasses, frequently have to ask people to repeat themselves, can’t smell the black mold in a house, can’t taste the difference between a hundred dollar steak, and a ten dollar steak, and can’t ever tell when my skin is wet, or just cold. I used to be adamantly opposed to body mutilation, like piercings, and tattoos. I guess I still am, but it wouldn’t bother me to have one, even if it seems permanent, but I know a secret: it isn’t. I’m young enough to still be around when we can replace any organ with a 3D printed upgrade. That’ll let me live long enough to see a time when my consciousness can be transferred to some other body; say a robin, a dolphin, or maybe a sentient tree. Posthumanism is looking forward to breaking the limits of our birth, which is why I love it.

Microstory 202: Generations

Genetic manipulation is not easy, but it does start making sense after decades of research. But even when you tamper with a subject’s genes, there are certain things that you cannot do. They will always have at least a hint of what they used to be. Turn a human into a giant fungus-eating aardvark-like creature, but they will always be an aardvark monster who was once a regular human. And so, a system of classifications was put in place in order to logically categorize the race of any given generation. The first generation in a new series is called Generation Alpha. These are subjects whose genes were manipulated directly. They were once one race, but have since been altered. Their scions are referred to as Generation Beta, and known as the first pure generation. They were born with the genetic traits desired by the genetic manipulators, as passed down by their parents. Generation Gammas are all unstable descendants of the new race following the Betas. Depending on the level of sophistication employed by the original scientists, this generational line can last for thousands, or even millions, of years. The thing is, if you want to create a new race, you’re going to have to wait for evolution to start working with you. Evolution already has its own ways of altering genes. Healthy mutations will provide the species with a better means of survival or procreation, and continue to be passed down, no longer as mutations, but as intrinsic qualifications. In order to rid the new species of genetic traits remaining from the original species, evolution has to weed them out naturally. At least, this is the best method. One could theoretically continue to manipulate the species through breeding techniques, but this runs the risk of causing more problems than it solves. The last unstable generation of gammas is actually called Generation Zero. Pinpointing this moment in time is inherently difficult, and is used more for mathematical and modeling purposes, rather than exact designation. Naturally, Generation One is the first genetically stable generation of the new species; the one that makes each individual a member of that species, and not a member of its predecessor. Generation Two is made up of all subsequent generations, and should continue to thrive barring further genetic manipulation, or other threats to propagation. The goal these endeavors is Generation Two, and for the most part, the people who started this process do not live long enough to see its end.
