It’s Not Quite a Smeerp

So, some worldbuilding notes on the nature of greenlife…

It’s easy to make the assumption that it’s just Earth-life in every way, especially since I tend to use the Earth-parallel names for things to create a sense of familiarity.

But a thing worth bearing in mind is that the Precursor genetic-distinctiveness harvesting vessel Incomprehensible Draconic Screeching collected its samples of Earthly life, the ancestors of Eliéra greenlife, around 360,000 years before present time.

This is, in short, before the domestication of anything, plant or animal, a process which has a lot to do with how modern plants and animals appear and, in some cases, behave. So while greenlife is from the same biochemical family as Earth life, it’s been through various different paths of descent that often result in a rather different organism.

Let’s talk some examples, starting with plants.

  • The múleth, or apple, is actually one of the least odd-looking cases, even though it wasn’t domesticated here on Earth until 10,000-4,000 years ago, mostly because it was being domesticated for many of the same traits. Thousands of cultivars exist; it’s just that none of them are the same cultivars. The most obvious thing, as you would see upon picking up a children’s book which includes the equivalent of “A is for Apple”, is that the modal Eliéran apple isn’t green; it’s golden. Green apples are a small minority among the cultivars. There are also more than a few purple apples, which while they do exist on Earth, are confined to one rare cultivar from a particular Tibetan region.

  • Oranges, on the other hand, don’t exist. The sweet orange as we know it today is the product of a deliberate post-domestication cross between the mandarin and the pomelo, and doesn’t show up in our history until a couple of hundred BCE, in China, not making it to Europe until well into the common era. Naturally, they have a whole lot of fruits bred out of the primordial citrus they did have (given that the genus Citrus is infamous for its hybridization), but while there is a rubescent citrus serelléth (“bloodfruit”) that is very popular in the fruit dishes and juicers of the Empire, it’s not a direct counterpart of our sweet orange. The closest direct counterpart you’ll find is something like a pinkish mandarin.

  • And then to grains. There is corn (by which I mean maize), but it wasn’t domesticated until around 10,000 years ago in Mexico, and even then, it looked nothing like the fat yellow kernels found in your local grocery store, which are entirely an agroindustrial creation. While the maize that was developed on Eliéra by the Aictectep shares some of the traits of our cultigen – insofar as those traits were necessary steps in turning it into a useful food plant for a civilization – the red-and-purple spatter-patterns, etc., of the primordial teosintes it was developed out of are retained in the Eliéran version, for example. (You can see a particularly good example on the planetary crest of Ponratectep (Talie Marches), being rather more prominent than even that world’s famed fire opals.)

  • One of the most immediately recognizable grains to our eyes would be rice, among other grain crops. It is, after all, amazing what grass varietals can do, and how robust they are. It is not as close a cousin to Oryza sativa as it might appear – and it is often rather more colorful that we could expect, compared to most of our commercial rice – but it’s very close to the same grain.

    What we might not expect as the number of cultivars of an offshoot species which has developed salt sensitivity to the point where it can be grown in, and even prefers, coastal salt marshlands and even floating seawater paddies.

    (And, of course, in very familiar-looking grasses, there is dyanail (“bamboo”), although the number of cultivars and engineered varieties in the modern era would be quite something to see.)

  • Coffee, on the other hand, does not exist either (it doesn’t appear in Earth records until the 15th century or thereabouts, unless you credit the 9th-century attribution of the legend about Kaldi’s buzzed goats). Esklav, while drunk like coffee, isn’t coffee; while Esklavea sendaren probably does share part of its ancestry with Coffea spp., they’ve both diverged a lot since then. It also has qualities that suggest a partial ancestry descending from Theobroma, but since the closest relation that bears to Coffea is that they’re both eudicots, it suggests someone’s been mucking about in their genomes along the way, and that’s not just the radioactivity.

    At least some cousin of Theobroma cacao managed to make it through close enough to be recognizable, even if the product doesn’t taste quite the same and is somewhat lighter in color.

  • And now to animals. Let’s start with man’s best friend, the dog, who might kind of be the same as eldrae’s best friend, the bandal.

    Well, sort of. See, the dog was domesticated in human history no later than around 15,000 years before present, but no earlier than 40,000-30,000 years before present, which is the point, we believe, at which they diverge from their now-extinct wolf ancestor (not the grey wolf). This ancestor doesn’t turn up in the record until around 129,000 years before present, which is still a good long way from 360,000 years.

    So while Bandal vocíëvis is definitely a wolf-like canine (family canidae, subfamily caninae, tribe canini, and probably-mostly subtribe canina, despite some likely admixture of Aenocyon dirus), you could make some interesting arguments as to whether it is or is not technically a member of the genus Canis. (It probably is; after all, Canis spp. were around well before the genetic harvest, and it is probably interfertile with C. familiaris, C. lupus, C. latrans, etc., because the Canis species are like that.

    In any case, they’re very good boys. Yes, they are. Even if they’re second or third cousins a couple of times removed.

  • “You think that’s cow you’re eating now?”

    If you order a steak *there*, you’re getting quebérúr. Now, quebérúr is delicious red meat, to be sure, but it’s doesn’t come from the domestic cow (first seen in the form of the zebu, maybe 8,000 years before present), or indeed from anything in the genus Bos, although it is one of the Bovina. The closest relative of the quebérúr on earth is its distant cousin the bison (Bison bison), as you might be able to tell from its distinctive humped back, but their common ancestor is back in the now-extinct megafauna. It is, in fact, a bloody big piece of pot-roast on the hoof, given that the typical quebérúr is around 3,500 lbs and 7′ at the shoulder; also known for their sharp, downturned horns, and thick, shaggy – like Highland cattle – black coats.

    Guess the radiation was good for them, huh?

  • The sevesúr isn’t exactly a chicken (domesticated about 8,000 years ago), either. Or a turkey. Or even a guineafowl. They’re certainly order Galliformes, superfamily Phasianoidea, and maybe even family Phasianidae, but further taxonomy is not available at this time.

  • And finally, we get to horses (domesticated on Earth on the Central Asian steppe, about 5,000 years ago). Well, sad as it is to say for would-be equestrians, none of the common riding animals on Eliéra are equines, or indeed greenlife. There are the cerrúr and the certárúr, both of which are bluelife hexapeds. The latter is a rather dull, plodding creature which one might consider analogous to a bluelife ox – mostly kept as heavyweight draft animals, and for leather and parchment, which can be repeatedly harvested from the skins they shed in spring; the former, while a intelligent and agile riding animal, has more in common morphologically with some of the larger species of deer than with horses, and is not terribly suited for any but light draft work.

So, this has been your quick trip into just how variant Earth-descended life got when you take it early and abandon it on another planet for a few millennia. Hope it was a somewhat interesting peek into the process of making exotic worlds a little more exotic.

Abstract:

The eldraeic genome is both a mosaic and a palimpsest with respect to its evolutionary and engineered history. Based on a phylogenetic analysis of the DNA sequence alignments found in the approximately 76% of the eldraeic genome shared with Pseudoeldrae archaea, encompassing both genes and intergenic regions, we have been able to construct a map of the greenlife segment of eldraeic genetic ancestry.

We conclude that the eldraeic genome is derived from the intermingling of two groups of Pseudoeldrae archaea, which while having considerable genetic overlap nonetheless possessed sufficient group divergence for sub-species classification. One of these groups is typified by specimens recovered in or near the Precursor site found in the Dragon’s Nest range of Greater Cestia, for which we suggest the taxonomical name P. archaea amanhadír; the other is typified by specimens recovered in or near the upper Unsea and lower Sweetshallow and the Dragon Gate Precursor site, for which we suggest the taxonomical name P. archaea aecalhaër. In both cases, these specimens date to the primordial period of approximately -360,000; later specimens show evidence of ongoing interbreeding or the potential use of artificial methods of gene transfer.

Furthermore, we have been able to trace the development of a variety of genes in the eldraeic genome from these primordial subspecies through to E. alathis. Of greatest interest are a number of genes whose development can be traced specifically to one or the other subspecies. Most prominent among these are the melanocortin receptor allele responsible for the distinctive skin and hair coloration of the Daën-lin and other lumeneldrae ethnies, present solely in the primordial P. archaea amanhadír; and the now-ubiquitous EPAS1 low-oxygen adaptation allele present solely in P. archaea aecalhaër. The rare epicanthic fold alleles found in some ethnies tracing their ultimate ancestry to the Ochale or Kanatai regions also appear to be specifically derived from P. archaea aecalhaér.

Author’s Note: Quebérúr

For your envisioning pleasure – and also because I secretly hope someone will send me fan art along the lines of a classic Old West painting set on said Mars-type world (beautiful for spacious pink skies and vermilion mountains’ majesty above its fruited plain of mottled green and blue grass, although the grain still comes in amber waves) – the greenlife quebérúr is a relative of the Terran bison. Specifically, it’s a separate descendant of Bison antiquus than our modern Bison bison, that has kept the 15%-25% larger size of the former (about 7.5′ tall, 15′ long, and 3,500 lbs.) Other relevant differences include having developed curled, downward-pointing horns, and being able to digest and mostly excrete the non-overlapping compounds across the bluelife/greenlife gap without being poisoned or sickened by them. Much the same parameters apply to their transbovine descendants.

Every bit as tasty, though!

Trope-a-Day: Humans Are Diplomats

Humans Are Diplomats: There not being humans, well, no, but since there is greenlife, the diplomatic hat is worn by one of Earth’s species.  Well, sort of – diplomacy and community-building is the hat of the dar-bandal, the uplifted dogs, who bring their talents for social cognition to this field much as they do to professional negotiation, arbitrage, community genesis, fixing, and path-pointing.

Trope-a-Day: Earth is the Center of the Universe

Earth is the Center of the Universe: Severely averted.  Earth is an unknown backwater somewhere out beyond the ass end of the Periphery, and has all the galactopolitical significance you would expect a world which, having once reached its own moon, gives up on space travel beyond its own orbit entirely to have.  In other words: none at all.

(The only revelation that might change this even a little is that it’s evidently the planet that the Precursors got Pseudoeldrae archaea and the rest of the greenlife family from.  But, honestly, even that’s mostly only going to be of interest to biologists.)

Trope-a-Day: Taxonomic Term Confusion

Posted by

1

Taxonomic Term Confusion: Taxonomy is even more of a mess than it used to be, having to deal with life originating separately (it is usually thought; see Panspermia) in a multitude of different ecologies, which then got intermingled by ancient and modern terraforming and accidents of star travel to produce the situation as we know it today.

Imperial taxonomy uses something that resembles our current system, but with an additional parameter right at the top of the tree to indicate the ecology which this particular species originated within (wherever it may be found now); i.e., adding to the classification of humans as kingdom Animalia, phylum Chordata, class Mammalia, order Primates, family Hominidae, tribe Hominini, genus Homo, species H. sapiens an initial level of classification along the lines of “ecology Terragenea“.

(Of course, not that this works perfectly even then: humanity – albeit not quite modern man – by virtue of ancient fossils turning up on Eliera with greenlife similarities, exists in the Imperial taxonomy as Pseudoeldrae archaea, ecology Cálenlethis; and in the event that they should discover us, I suspect we would take about as well to being reclassified as Pseudoeldrae novis about as well as they would take being shoved into genus Homo; which is to say, not at all well.  This is the sort of thing over which wars, or at least vicious academic infighting and people being cut – as in “cut direct”, not as in “I CUT YOU”… well, at least most of the time – at professional conferences, start.

It also doesn’t help that the eldrae, E. alathis, E. anthalis, or E. kirsunar, are already a taxonomic mess by virtue of having at least as much claim to being in ecology Fidúrlethis [bluelife] as ecology Cálenlethis; hybrid engineered lifeforms are like that.  And the continued production of neogens makes this problem worse by the day – while, yes, the Applied Biotics, ICC Bactry Template Organism EC-7 is descended from organisms in kingdom Bacteria, it’s descended from about a dozen of them, taken apart and the best bits kept.  This is hard to classify in anything resembling the normal manner.)

There are also at least two alternative partial taxonomies in use simply because they’re useful: one, a classification of species by their biochemical features, simply because it’s useful for some purposes to have all the methane-breathers or all the silicon-based life, and so forth, classified together regardless of origin; and another more approximate classification by homology alone, because for non-biologists travelling between planets, it’s useful to have relatively simple terms to call all the avioids, the ichthyoids, the arboroids, and so forth even if they’re not related by anything but general similarity.  (Which terms I still, despite this fine feature of the “original language”, I still “translate” as “bird”, “fish”, “tree”, etc. when writing just like the first set, because the clarity in the original language is the bloody-minded wordiness in English.)

On the use of “race” to mean “species” in particular: In formal speech they’re usually good at maintaining the race/species distinction, but then, the whole race concept is also a mess – inasmuch as it used to be that the former was used in much the same loose sense as we use it for natural phenotypic distinctions within a species, and then clade came to be used for artificial ones (as people started producing aquatic people, photosynthetic people, space-adapted people, etc., etc.), which are messy categories, because they overlap quite a lot (one clade can include all races; one race can include all clades), but some clades rewrite for perfectly good reasons the same phenotypic elements that were used to define races (for practical reasons: all naked-to-space-adapted-clades have high-melanin [etc.] skin for radiation protection, but all photosynthetic clades have to have low-melanin skin to avoid conflicting with the chloroplasts [etc.], for example), and some clades exist to be cosmetic phenotypes that are essentially new races in the casual sense, and aaarrrgh.

(It’s clade that’s used for classification, when relevant, because it’s the one that tends to be medically relevant, environmentally important, and so forth, on a regular basis.)

Trope-a-Day: Panspermia

Panspermia: Not proven in the general case, any more than it is today, and probably substantially less – different evolutionary trees and biochemistries surely look as if they had different origins.

Confirmed in some specific cases – Eliera, for example, derives its life from three sources: bluelife, which is very clearly descended from the native life of Revallá (Imperial Core); greenlife, of unknown but extraplanetary origin; and silverlife, descended from feral Precursor nanomachines – but then, Eliera is an artificial planet, so that’s to be expected.  And many garden worlds are the product of ancient terraforming, such as the many methane-based garden worlds in the vicinity of the Elmon Rift that were terraformed by the ancient and extinct methane-breather civilization that thrived there around 33 million years ago, and so possess life which obviously originated offworld.

But natural panspermia, or a common/intentional aliens-seeding-life origin?  Very much not proven, and looking increasingly unlikely.

In Many Shapes and Forms

The ecology of Eliéra is uniquely complex in the known Associated Worlds, since it is not, as most are, the product of either natural evolution, or ancient or modern ecopoesis.  Rather, a few unique survivals excepted, its ecology is a mixture of species from three separate origins and their coevolved descendants; referred to as bluelife, greenlife, and silverlife.  It is believed that the progenitors of these ecologies were transported to Eliéra during the tenure of the Precursor species, and in the case of bluelife and greenlife, that their descendants reflect those ecologies which were best fit to survive and adapt to the world in the absence of the Precursors and thus anyone to tend their gardens and biological preserves.

Both bluelife and greenlife are examples of oxygen-breathing ecologies using the common L-protein/lipid-D-carbohydrate biochemistry, with nucleic acid-based information-storage molecules; although the encoding used for these information-storage molecules differs greatly between the two classes.  There is considerable overlap in the specific compounds (amino acids, for example) used by the two classes, to a sufficient extent that heterotrophs and saprotrophs of both classes find the other edible, although in many cases lacking in some essential nutrients.  Indeed, some members of each class, including the sophont species of Eliéra, the eldrae, now naturally require some essential nutrients from each of the classes in their diet.  (The eldrae, among some other large animal species, are particularly notable for having adopted some symbiotic bluelife organelles into an essentially greenlife makeup, giving them their distinctive indigo blood.)

Bluelife, a class including a large number of non-cellular and single-celled organisms, also includes among its complex organisms the majority – around 85% of species – of Eliéra’s plant life (whose distinctive and predominant blue photosynthetic pigment is the source of the name of the class), a smaller percentage – around 75% of its species – of its animal life (including both scaled and furred hexapedal land animals, four-winged birds, duodecids, and tubefish), 90% of its fungi, and all of its algae and plankton.  It is strongly believed to consist of evolved and/or modified forms of life transplanted from the nearby world of Revallá, which used a near-identical biochemical substrate and set of body plans, the more so when Eliéra bluelife’s adaptations to coexistence with greenlife and, to some extent, silverlife are considered.

Greenlife also includes a large number of non-cellular and single-celled organisms, along with another 14% of Eliéra’s plant life (again, the green photosynthetic pigment, chlorophyll, gave its name to the class), the remaining (with very few exceptions) 30% of its animal life (including both scaled and furred quadrupeds, two-winged birds, arachnids, cetaceans, and bony fish), and nearly 10% of its remaining fungi.  The origin of greenlife is unknown; no world currently known to the Imperial Exploratory Service appears to have a compatible ecology.

The final class of life on Eliéra is the silverlife, a class of lifeforms descended from what are believed to be a number of simple Precursor nanites which survived the destruction of the Precursor civilization, many of them mutated by radiation effects and evolved over time.  By far the vast majority of silverlife is composed of microscopic organisms of the crystallite and metallite kingdoms, of which the most notable are the saerymaharvéi, descended from simple assemblers and responsible for the many crystal deposits and outcroppings across the surface of Eliéra.

Silverlife also includes some simple macroscopic organisms, including some silicate pseudo-plants found in sunlit, rocky areas of appropriate compositions (most prominent are cikril, which forms tall, slender columns of translucent crystals, charged with photoelectricity, and cikrieth, a swamp-dwelling variety of cikril which extracts materials from seawater and forms intertwined resource-sharing complexes), and some colonial organisms roughly analogous to slime molds.  These together make up the remaining 1% of Eliéra’s plant species, and 0.5% of its fungi.

Silverlife in general has many aspects and features in common with the lower lifeforms of Galáré, the homeworld of the galari; while the evidence suggesting their origin in Precursor nanotechnology remains convincing, scientists are studying the possibility of a link between known Precursor nanotechnology and the ecosystem of this world.

Trope-a-Day (R): Ancient Astronauts

Ancient Astronauts: Almost certainly happened in at least a few times and places, for the same the-Galaxy-is-old-and-relatively-life-rich reasons that are why half the systems in it are practically knee-deep in elder-race trash.

Also, technically, connected with the origins of the eldrae and greenlife in general from prehistoric Earth, although given that Earth is not found and not likely to be in canon, no-one has a clue where those fossils of so-called Pseudoeldrae archaea came from, or exactly what they have to do with anything anyway, even if we’d clearly recognize an offshoot of genus Homo if we saw one.

Averted in the “alien abduction” meme sense, just because, as mentioned, lighthuggers ain’t that subtle.
