#Microevolution

[theriu]

Just reading Genesis and now I’m thinking about how even some Christians argue that Earth can’t literally be 6,000–7,000 years because of all the varieties of animal subspecies, like microevolution doesn’t WORK that fast, it MUST be a metaphor that Creation only took seven days!

But if you’re going by the Bible, it also says people used to live over 900 years? Which def isn’t how we humans work anymore? And all humans and animals today descended from those on the Ark, yet we don’t hear of inter-family marriage being forbidden for a few generations at least, possibly suggesting intensely rich genes pools that hadn’t yet been thinned out enough for closely-related unions to cause genetic deformities?

I’m just saying, we might be assuming a lot to think biology today is anywhere NEAR identical to what may have been goin’ on in the early days.

Microevolution can be used to predict longer term evolution, new study shows

Microevolution can be used to predict longer term evolution, new study shows #evolution #microevolution #macroevolution #study #climate #evolvability #change #selection #science

A new paper published in Science, Evolvability predicts macroevolution under fluctuating selection, shows that evolvability, which is the ability of populations to evolve and adapt over just a few generations, can help us understand how evolution works on deeper time scales. While our relatively stable past environment has limited selective pressures, current climate change has caused more rapid…

Thinking about my high school biology teacher who was Christian and critical of evolution theory and he believed in microevolution (small scale, e.g. evolution from wolves to dogs) but NOT macroevolution (evolution from species into new different ones). Okay

INTERVIEW 016

with. hazel callahan

includes. nerd!tutor!hazel, inexperienced!hazel, fem!reader, fingering (r receiving), oral (r receiving), tit fixations, corruption undertones, semipublic sex

→ kinktober masterlist

She’s been staring at your tits. 

Ever since you walked into the study room and shrugged your cardigan off, skin then overheated with the walk you’d completed across campus, Hazel Callahan has only looked at her notes, or your cleavage. There were maybe two times where she was able to peel her eyes away from your exposed skin to look you in the eye, but almost instantly they gravitate back downwards, as if looking at your tits was more comforting than your eyes. 

Throughout the session, as you copied down a combination of what she was telling you and her notes (an array of question marks beside words that were entirely too difficult to spell in one go), your smirk grew more and more. You figured if Hazel was going to be shameless about her staring (or perhaps oblivious), you’d be shameless about your intentions, too. 

Elbows pressing into the scarred wooden table, biceps attempting to meet each other, separated by your tits that end up squished together. She notices, of course she does, stuttering over her words and clearing her throat an alarming amount of times.

“And then just make sure you know that microevolution is whenever changes produces only after many generations, like with the ––” 

You interrupt her, “don’t you mean macroevolution?”, and her eyes finally snap back up to yours. Her eyebrows raised, her lips parted. 

“What?” She raises a slender finger and presses her glasses up her nose. You lean a little closer, smile a little bigger. 

“You said microevolution. But you described macroevolution.” Hazel sits for a second, eyes lifting as she looks at the ceiling in thought, and just when they lower, assumingely to find your tits again, you speak once more. 

“Maybe we should take a break? You seem a little out of it, don’t you think so, Haze?” It’s a nickname you’d never called her before, and you lay it on extremely thick for the first time, dragging the syllables out and layering them with heavy sultriness. 

The intended effect is achieved; Hazel with wide blue eyes and red cheeks. 

“Uh, yeah, s-sure.” 

The proposed ‘break’ turns into you teaching Hazel something for once. 

Her head is just visible enough in the space between the table and your lap, her eyes shining with wonder beneath her glasses, even in the shadows she sits in, the tips of her fingers just breaching your leaking entrance. 

“Like this?” She asks, all shy and timid and it’s so cute that you’re grinning instantly. 

You nod. “Yeah. Keep going.” 

She does as told, sliding her fingers into your wet heat knuckle by knuckle, her pace agonizingly slow as if she’s afraid of hurting you. You attempt to hint to her that you’re not breakable whenever she has two fingers in you to the last knuckle, and they sit still, clearly unknowing on what to do next. 

You start to grind, holding onto the arm rest of the chair you sit in, spreading your legs even further as you push and push your hips into Hazel’s hand. She stares at you all the while, starstruck, mouth agape. Adorably, you notice her glasses starting to fog up, too. 

It takes her a moment, but she starts to move her fingers until you’re meeting in the middle with your combined movements, her thrusts and your steady push and pull. 

It’s coordinated and planned for a moment, you giving Hazel simple instructions that’s easy for her to follow. 

(“To the left a little. Yes! Right there, Haze. God, don’t stop. Keep going, just like that.”)

And then, in the moment where your eyes are closed, pinched together in bliss, there’s the feeling of a tongue, wet and warm, on your clit. It’s brief, just barely more than a jerk, almost as if it’s accidental, but when you unfasten your eyes you’re met with Hazel’s mouth just an inch from your cunt, his eyes staring up at you to gauge your reaction, you realize she's done it on purpose.

“Again.” 

She repeats it, this time swirling her tongue around your clit just before gliding it down the area beneath it. She’s clearly inexperienced, licking around your cunt in a non-uniform fashion and her glasses nudging against your skin each time, but her fingers are still probing that spot within you and the stimulation of her muscle against you is enough to have you losing it. 

You’re close, back arching, hips pushed further into Hazel’s mouth. Your hand finds her short hair, nails digging into the fragile strands at her scalp, perhaps a little too harshly. But it’s not like she cares about your intensity, because she slides a hand up your chest and pulls the neckline of your tee down, audibly groaning whenever she’s met with your bare tits. 

When you cum, it’s from the impressive combined stimulation of Hazel’s mouth and fingers on her dominant hand abusing your cunt, and the fingers of her non-dominant hand pinching your erect nipples.

[lifesteal-headcanons]

All these headcannons debating whether or not a lifestealer is human or hybrid or demon…. I say that it all varies depending on which season and which time. Sure, they start out with their normal forms. But as lifestealers come into contact with all sorts of violence, void deaths, hacking, etc, their code is warped and corrupted by those influences. And thus, their code adapts to save them or help them, sometimes at the cost of humanoid traits. Think microevolution.

Lifestealers are a unique set of players, and can’t be categorized as either human or not-human. They are the product of their origins and experiences and general mindset, ever evolving as their surroundings and allegiances waver. Some lifestealers can even have different code effects for the same event.

Example: Vitalasy used to resemble a human with fox hybrid traits, but as he became more and more involved with the Wormhole and becoming a tyrant, he started to change. His eyes became more and more fox-like, and his hood starting covering more and more of his face, giving him a more sinister, unapproachable appearance. It sure helped intimidate his enemies and maintain his facade. Example: In season five when players were possessing one another to win wars, personalities would literally clash. Possessions would often be accompanied by glitch particles, and patches of the original player’s skin peeking through. Sometimes, the possessed body would have a mind of its own too, using the possessed user’s speech patterns, habits, and tics. All in an effort for the player fighting against the possession to regain control of their body.

Example: In season four, to survive the barrage of hacking, Parrot’s code dulled his ability to sense banned objects to save his admin-coded self from insanity. Whereas the 3HT actually became more sensitive to it, to become aware of imminent attacks early on and give them more time to prepare.

[sqarletsworldlesswandering]

On the HTTYD × Worldless train

Imagine Dragon Rider! Duo meeting the Riders themselves (I forgot what the offical group name is...)!

Also/ Alternatively: Dragon! Duo meeting the riders, cue chaos on all members because they're all confused... wonder what they'll look like as dragons?

Maybe they both have feathered wings and manes?

I forget if they even have an official name, I think it's just the "Dragon Riders." Been a hot minute since I've watched anything outside of the movies tho.

That's gonna be an interesting meeting. I...mostly see it going well, as long as no one gets super defensive or flighty? But....we'll see how that goes with this crew. Probably depends a little on the timeframe. If we land somewhere just before or after the second movie, I can see the general feeling being "Wait other dragon riders? AWESOME!"

Ooo, meeting the riders as dragons will be interesting, especially if they retain all of their intelligence/sapience (as opposed to simply being very smart animals). Hiccup and Fishlegs would be ecstatic, I imagine Astrid is going "hey can we slow down for a second you two-", and Snotlout and the Twins are... quite possibly bugging the duo already, who knows. At least, the Twins would be. Snotlout idk. That or the Duo looks so unfamiliar that they're all kinda hiding in fear waiting to see what they do.

As for what they look like, I'd need to go reference the ask, but it'd definitely be cool to pull some inspiration from eastern dragons, since I don't think we see much of that in the series. I think most of what we see riffs more on the western dragon?

At any rate, manes of some kind 100%. Not too sure about the feathered wings? Maybe a mix of wings and scales though. It'd be cool if they both sorta look like the same species, but also have enough differences to definitely not be the same type of dragon anymore. A sorta microevolution/adaptive shift, probably. Edda definitely still hates water, Aven might seriously hate sand/dirt particles in vast quantities (cue Aven staying as far away as physically possible from Edda while she takes a dust bath, unless she uses snow instead. That or she just....vibrates for a moment to shake stuff loose).

Some clarifications about the various human races question. (https://scriptaworld.wordpress.com/2024/04/01/submitted-via-google-form-where-do-various-human-races-come-from-when-building-a-sci-fi-story/) First of all, my story is sci-fi mainly because it takes place over a dozen planets over multiple solar systems in a universe I've created from scratch. All the humanoid species started from the same ancestors and spread over the universe in the distant past due to outside interference and had parallel evolution. But the creation of racial traits is microevolution due to local environment unchanging and people not mingling. How do I build all these various things across planets. On earth, we know how race evolved and where people have been and are still discovering connections. But I'm creating entirely new planets and new but habitable terrain. So.. microevolution will likely not be the same across different planets. How can I create such variations? How similar will these microevolutions on different planets? How do I make the terrain and microevolution match up with history on those particular planets? Racial dynamics are even more fluid and are not caused by evolution at all, it's just society itself. Also because the history will be completely different than real life... that will completely change what kind of racial dynamics that might be possible. Such variations will however, be rather important for identification however... race also the the result of how to give these variations names that will help distinguish someone from others. Regardless of any solving of societal issues arising from such tension, when people share or don't share microevolution traits - it is a distinguisher.

Tex: People on Earth look like people from Earth. Presumably people from Venus will look like they’re from Venus, so on and so forth. No matter how large a planet is - and planets are very, very large - there will still be baseline environmental factors at play, such as a planet’s magnetosphere and atmospheric gas composition. There might be a few degrees difference in particular nice environments, but it’s not generally large enough to produce entirely different species unless you’re keen on segregation.

To pull from my extant example, would someone from southern Venus look noticeable different from someone on northern Venus? What about a Venusian living at a higher elevation than another Venusian living at a lower elevation? This would likely introduce some genetic drifts if the societies in different areas only reproduced with their neighbors, yes? Would they all still be people from Venus? Also yes. From an outside perspective, you would likely be able to distinguish the commonalities that make it a singular race.

Addy: If you’re looking at microevolution, I’d say to look at Earth for some ideas. Extreme changes, like gills or tails, probably won’t happen - they’d take significant amounts of restructuring in the body to get to that point. But smaller changes are totally doable. Maybe some people can hold their breath underwater for significant periods of time due to enlarged spleens* and changes in their blood. Maybe you’ve got people adapted to planets with thinner atmospheres, with traits like what you’d find in high-altitude populations –  more nitric oxide in the blood, better energy reserve molecules, more efficient red blood cells, and/or more efficient lungs (such as IRL Sherpas or Andean people). Gravity/climate differences - how do heights vary? Maybe some people are average tall (like Danish people, who average ~5'6" for women and ~5'11" for men) or average short (like Himalayan people, who average ~5' for women and ~5'4" for men). Arm length, general disorders (thalassemia, for example, helps provide resistance to malaria), muscle insertion (tradeoff between strength and finesse)... you’ve got a lot of flexibility for different traits.

* While the IRL Bajau people can hold their breath impressively long (3-5 minutes), there’s a common figure floating around that claims 13 minutes. One of the men being interviewed claimed he could hold his breath for up to that long in his youth, but I have seen no confirmation of anything like that.

If you’re looking for ideas on how to get terrains and traits for those terrains, think about the problems that could arise from a given environment. Lower gravity means thinner atmosphere, for one, but also means less pressure on joints and fewer demands on bone and cartilage. Dark vs bright planet, how do eyes change for that (blue-eyed people actually have better night vision than dark-eyed people, but can have light sensitivity issues during the day)? Humidity, climate, all kinds of things. Play around with it.

And racial dynamics… don’t forget that things as simple as accents can absolutely change how people perceive in-group vs out-group behavior.

trans women who aren't really enthusiastically out until their late 20s eventually creates a wondrous phenomenon of "milf with the whimsy and enthusiasm of a teenage schoolgirl" which i think is an important microevolution in our ecosystem with the one drawback of despite many flocking towards these beauts to call them mommy they are in dire need for someone else to be the mommy for them so media literacy and acting skills are both important things to cultivate which is best done doing erp with strangers on the internet rather than the traditional school of "band class" which does not produce the desired chemical reactions as instead it creates a person who thinks standing around like waluigi is considered a joke on its own

[wendelsae]

Dune factions & what they think of Evolution

in general - outside of the narrow classes of imperial schools & ruling houses, the vast majority of mankind has extremely vague ideas of their origins & history. for them, history consists of the ever-fixed Butlerian Jihad, and then whatever they glean out of religious scriptures and what bits of their House history the rulers wish to propagandize. many of the First Islamic farmers on Caladan assume that the Trojan War occurred fairly recently, on their own planet- Achilles, he was one of the Sardaukar, right?- admittedly not helped by the Atreides giving every settlement and landform a Homeric name. many of the lower classes (and some of the upper) disbelieve & regard with suspicion the narrative of mankind descending from a single planet, and hold that their ancestors have always dwelt on the planet they now live on. the sway of religious tradition dictates whether they believe that man was created separately on many planets by God at once, or that those planets & races, and oft the Imperium with them, have always existed & always will. any artefacts you show them to the contrary they'll dismiss as AI-generated.

Sardaukar - see evolution as a bitter process of the fragments of God blessing some branches of Apam Napat and cursing others- Jacob have I loved, Esau I have not. believe themselves to be endpoint of evolution, or rather the point at which a form of life has become strong & restored enough to be able to go forth and liberate all other men from the war of all against all, and give them the Law.

Ixians - conventional monogenetic creationism. won't shut up about the Wisdom & Art of the Creator.

Fremen - acutely aware of microevolution, having observed it in other life & in themselves over the ages, and the Sayyadinat can give account of this clearly. believe adaptation to an environment to be non-random and brought about, poetically speaking, by the jinn of that land teaching the jinn of the species. usually answer talk of macroevolution with a shrug, though the Kynes have recently taught them about it.

Tleilaxu - deeply concerned with evolution, and think that it's Mara and keeps (non-)beings from God. hold that evolution is circular & unchanging.

Bene Gesserit - bitterly & obnoxiously insistent on the scientific truth of atheistic & random evolution; abhor polygenism & autochthonism as the degeneracies of this feudal age. a simplified account of evolution & human origins, adaptable to local religion, is a standard parcel of the Panoplia Prophetica, along with some elementary eugenics that even peasants can benefit from (avoid inbreeding, ancestral traits can manifest after generations of being unseen, traits are inherited from both the mother & the father...)

Spacing Guild - specialization is bittersweet.

Atlantis Expedition: Science Division Departments - Life Sciences Department

We're a bit further from the original post, having already done the medical department, so now it's time for the Life Sciences.

Much like the medical department, the notes for this underwent significant revision (nearly entirely re-done), to better granulate expectations for the department's duties and how they interact, primarily, with the medical department. Below is the original estimation, with struck text indicating revisions:

> Head: OC > Contains: Earth biologists, bio- & biochemical engineers, astro/xeno-biologists, botany, environmental chemistry, zoology, microbiology > Function: Auxiliary to Medical Department needs > Examples of function: pharmaceutical synthesis, analysis of unknown species, biological database creation, gene therapies (pharmaceutical adjacent) > Personnel quantity: 1 (Head) + 2 (Earth biologists) + 2 (bioE & biochemE) + 1 2 (astro/xenobio) + 1 (botany) + 1 (envchem) + 1 (zoo) + 2 1 (microbio) = 11 > Personnel quantity: 1 (Head) + 1 (physiologist) + 1 (geneticist) + 1 (astrobiologist) + 1 (xenobiologist) + 1 (microbiologist) + 1 (botanist) + 1 (zoologist) + 1 (biomedical engineer) + 1 (biochemical engineer) + 3 (medical laboratory scientists) = 13 > A/N: Both biologists also have training/specialization in genetics/gene mapping (assists both Carson and Katie), some input in requesting gate missions based on in-house needs > A/N: Focus is on medical logistics and supporting Medical Department needs, research parameters fulfill SGC outlines of studying microevolutions and drug technology development.

Following on the parameters of 1) putting people through the inter-galactic theoretical shredder is expensive, and 2) said gate shredder will only be open for a certain amount of time, the vast majority of this department's work will be geared toward the analysis, creation, testing, and preparation of pharmaceutical drugs and other inventions of medical context.

Think compounding pharmacy but better equipped, and capable of researching new things - this department specializes in medical logistics. Wikipedia has a better description of this, so I'll pull a quote:

Medical logistics is the logistics of pharmaceuticals, medical and surgical supplies, medical devices and equipment, and other products needed to support doctors, nurses, and other health and dental care providers.[1] Because its final customers are responsible for the lives and health of their patients, medical logistics is unique in that it seeks to optimize effectiveness rather than efficiency.

As with most things contrived by the SGC, there's going to be a lot of blended specialties and overlap, heavily bolstered by technological innovation. These are people Carson Beckett likely hired, or at least had a heavily-weighted opinion when Rodney was going through the application packets, because the Life Sciences is at a one-step remove from actually handling patients, and handles a significant amount of labwork and research.

The revised numbers weigh heavily in favour of biologists, due to the sheer breadth and depth of the subject, and the fact that most of these are likely to have some sort of SGC training that would make them well-versed on what to expect on the expedition in terms of disease research and thus treatment solutions.

Unlike the medical department, which handles patients directly in different aspects, this is all one "team". If you're looking for a group of scientists that can technically have the same generic appellation that would make one of them go, "Well, actually-", this is the place to look.

On to the breakdown, notes included:

> Earth biologists  » 2x of these  » Specialties?   ⇛ Human physiology (academic rather than medical context)   ⇛ May function as a knowledge base to study how the physiology of the expedition changes by long-term habitation in Atlantis, assists in studying long-term effects of the ATA gene therapy, development of knowledge base as Earth-based physiology changes in reaction to Pegasus galaxy habituation (exposure to local diseases, eating of local foods, etc)   ⇛ Geneticist   ⇛ Same as the human physiologist, but in a genetic context   ⇛ Studies genetic drift of the expedition and builds knowledge base for comparisons of baseline to genetic mutations that build up over time > Astro/xenobiology  » 2x of these   ⇛ 1 of each  » SGC special  » Studies the species and speciation of non-human humanoid species   ⇛ Imports from studying the Jaffa, Goa'uld, and Replicators (xenobiologist in particular)   ⇛ Overlap with parasitology and immunology/histocompatibility (Goa'uld and Jaffa, respectively) > Microbiology  » "Most microbiologists specialize in a given topic within microbiology such as bacteriology, parasitology, virology, or immunology."  » Studies the species and speciation of bacteria, algae, fungi, and some types of parasites and their vectors > Botany  » Study of species and speciation of plant species  » Outline of botany > Zoology  » Study of species and speciation of non-human animal species  » Outline of zoology > Biomedical engineer  » REVAMP from bio-engineering  » Actually makes the pharmaceuticals based on the feedstocks and processes biochem engineers designed for them   ⇛ Works with biochem engineers to feedback on the design process of drug manufacturing   ⇛ Biologics as well as inert (in comparison) materials for drug development   ⇛ Pharmacology    ⟹ Most likely all drugs are powdered for shelf-stability and ease of transportation     ⭆ So their responsibility in this would be referencing the SGC formulary (how many books to a Frasier) on reconstituting these drugs      ➾ Compounding     ⭆ What about topical prescriptions? Gel-based? Powder for gels, as well      ➾ More complex formulation     ⭆ What about gases, for sedation?      ➾ Probably compressed canisters? > Biochemical engineer  » Would not have existed in the early 2000s as a field related to process engineering, so an SGC special  » Also useful for researching food preservation methods  » Synthesizes information from peers in this department to create pharmaceutical drugs and their manufacturing process > Medical Laboratory scientist  » Does the legwork of processing samples for everyone, so needs a wide range of skills   ⇛ 3x of these   ⇛ Specialties    ⟹ Immunology/histopathology/hematology     ⭆ Human tissues    ⟹ Microbiology/bacteriology     ⭆ Bacterial forms of infection    ⟹ Virology/mycology/parasitology     ⭆ Non-bacterial forms of infection      ➾ Routes of non-bacterial infection > Environmental chemistry  » Role covered under biochem engineering  » Biochem engineers can cover the study of pollution that envirochems specialize in

Environmental chemistry section preserved to properly annotate the revisions, and what their original role was supposed to be (i.e. study pollution to solve Earth's pollution issues).

It occurred to me, while revising personnel lists, that the biologists in particular will need to divide their research into some broad categories, if they want to properly develop their research topics and what category of formulations they would require from the non-biologists in the department.

We have human species, yes, but that can be parsed from Milky Way to Pegasus galaxies, and from there Earth-based humans vs Jaffa (vs Goa'uld), and Pegasus-based humans (presumably humans, as they probably wouldn't know for sure that the Ancients were the default sentient or even default humanoid species in the Pegasus galaxy).

The human microbiome is incredibly important to understanding homeostasis, disease pathology, and various other interconnected factors. Because of this, the medical laboratory scientists will be heavily relied upon to develop cultures for study. I'm willing to believe that they have some nifty adapted technology to help them study all of these subjects I've shoved under multiple umbrellas, in the form of culturing processes, reagents, microscopes, analyzing software, preserving agents/methods, and the like.

After that, testing to see how these diseases - or potential diseases, if someone in the Pegasus galaxy hosts a bacteria, virus, fungus, or parasite that their immune system is natively robust to - might infect a member of the expedition. This is where a lot of back-and-forth would be done between the Life Sciences and Medical departments, so it wouldn't be uncommon to see people like, say, Biro (pathology) and Katie Brown (botany) jointly doing research on a pathogen.

There's already a lot of canonical evidence to support this specialist overlap being a necessary concern, from the the Hoffan drug (and the subsequent Michael arc), John Sheppard's infection from an Iratus bug bite in Conversion, Asurans, Lucius' drug, the crystals of M3X-387, Kirsan fever, Jennifer Keller's infection from something that was turning her into a Wraith hiveship in The Seed, and the Second Childhood parasite.

Depending on the type of infection, a lot of the personnel in this department will coordinate with each other to develop a knowledge base, including potential therapeutic remedies. If something already in stock cannot be used (see: a potential cross-applicability of penicillin), then they might make a request to the head of the expedition for a gate team to travel based upon any information they might have (ex: Teyla and Ronon going out for samples of the Enchuri plant for treating Kirsan fever).

Because of their support role as a department, the fact that all the scientists here can be used as in-house reference for the medical department, and their unique position to recommend gate missions for consideration on the roster, this department functions well as a bridging gap for the various demands the expedition has placed on them by the IOA and the SGC.

Total Life Sciences Department Personnel

Head of Department: 1

Biologists: 5

Engineers: 2

Laboratory Scientists: 3

Botany: 1

Zoology: 1

Total total: 13

I'll be going over canonical personnel such as Katie Brown in their own posts, but for now this is a general accounting of the expedition’s life sciences department.

What is the difference between macro and micro evolution?

Dr. Morteza Golsorkhi

https://instagram.com/dr.golsorxi

Microevolution and macroevolution are both types of genetic changes in a population over generations, but they differ in scale and time frame:

MicroevolutionOccurs within a single population over a short period of time, like a few generations. It results in small, noticeable changes, such as an increase in the frequency of a gene, but doesn't lead to the emergence of a new species. For example, the frequency of the gene for dark wings in beetles might increase from one generation to the next.

MacroevolutionOccurs over a much longer period of time, like millions of years, and can affect taxa above the species level. It can result in larger changes, such as the evolution of new structures or the emergence of new species. Macroevolution is the accumulation of microevolutionary changes over time, to the point that a population is distinct from other populations and is considered a new species. For example, the evolution of mammal diversity over the past 100 million years can be explained by modifications to existing organs, like the evolution of elephant tusks from canine teeth. 

summary 👇🏻

(Microevolution happens on a small scale (within a single population), while macroevolution happens on a scale that transcends the boundaries of a single species.)

Can we get some lore about Time Keeper

Lore about Time Keeper

Time looks over the Sacred Timeline, obviously. Everything that happens has to be approved by them. Big hurricane sweeping through a coastal town in the Victorian era? Sure, won’t be too disastrous and we need a bit of spice around here anyway. Microevolution of a species? Yeah we can work that in.

Their realm is a vast desert surrounded by an ocean of white water. An array of hourglasses and clocks litter the landscape, acting as the foundation of the timeline.

Since the beginning, Time’s power has been unstable and finicky. They’re constantly patching holes and stabilizing the timeline, hourglasses, and clocks because they will randomly break.

OFnR (Placeholder name for my story surrounding Swift) starts with the Sacred Timeline becoming unstable and starting to unravel. I’m a panic, Time had to freeze a section of the timeline, which caused a chain reaction and for the hourglasses (holding up the older half of the timeline) to start to crack.

Time immediately called Space and asked them to keep an eye on the timeline while they went into the timeline to get a patron and try to fix it from the inside.

So yeah that’s what Time is up to

You could say they’re

Having a time

30.10.23 — PM UPDATE

today was semi-productive! had a really good breakfast, but a super late start to my day in general so energy levels were low regardless. i managed to get all of my chemistry revision done I had planned for the day.

but i only got microevolution and speciation done for bio... however i'm not too worried because i still have seven days, so i'll catch up on what i left out today tomorrow!
