Anomalopteryx didiformis AKA the little bush Moa
A bone from a fossil had its DNA examined and scientists were able to see what natural abilities the bird had when it was alive; like seeing in the ultraviolet spectrum.
Located in New Zealand for millions of years until humans arrived.

sauropoda is a clade of saurischia that includes some of the largest dinosaurs we currently know of. if i'm going to submit something to you it's going to include these guys. they include some familiar faces like the brontosaurus. but the largest specimen within this group is a giant barosaurus fossil.

they've inhbabited every continent (including Antarctica!) and give us those comically large prints we're so fond of zooming out on.
another good giant friend of mine is the colossal squid. why do they keep making bigger squids? because i love them. i love their huge eyes and big fights with sperm whales. i love their elusiveness. i love that we went "kraken?" haha very funny. cthulhu? sure guys. and they EXIST <333

and charismatic megafauna are cool and all but have you considered something a little smaller? maybe a Black Capped Chickadee? they tend to travel in groups or two or more when they're flying outside the nest and their call "chicka dee" functions as a warning call of increasing intensity depending on how many "dee"s they add.
and bugs? here's the thing: i have fought with Polistes metricus for years growing up. have they stung all of my loved ones? absolutely. do they also eat an invasive species of worm in my area? yes. and while these guys will sting you without a second thought and fly away laughing, they are a necessary evil. just like the birds, they stop for a sip of water. they are, i must admit through gritted teeth, an important part of my ecosystem.

Ok so I'm taking a genetics class right now and in lab we've been given fruit flies with different mutations that we need to breed over the course of the semester.
Now, first thing I learned: fruit flies don't eat fruit. They eat yeast. They eat the yeast on fermenting fruit. They can not actually eat fruit. Their name is a lie.
Secondly, one of the two mutant lines I was given to cross are flies with the apterous mutation, aka they're wingless. I feel so bad for them, they can't do the one thing they're named for, they cant fly.
And then I realized. My fruit flies are in truth insects that eat yeast and can't fly.
Anyways, I've been calling them my yeast crawls and I am their god now.
7 to 8 days at the soonest, but im projecting closer to 2 weeks. I expect a fully functional industrial civilization worshoping me by the end of the year.
so long as the evil bar eyes don't bring upon their downfall.

I am viscerally imagining this in my head right now. Rehydrated potato, yeast, and ether.
I've started smelling it in places not in the lab and I don't know how to handle this.

Man do I have a story for you!!!
So due to when my parental generations of flies pupated, the yeast crawls emerged as adults about a week before the other flies I have been assignedto breed them with emerged. Said flies have what is called the bar eye mutation, which changes the shape and size of their eyes.
So, flies hatching roughly 5ish days apart, results in me having collected my female apterous flies before their boyfriends had emerged. This ment there was a nice isolation period that allowed me to see that yes, all of the yeast crawls I had selected were in fact healthy and doing great in their new homes as they waited to get their boyfriends. On friday the bar eyes emerge and I am able to introduce the ladies to them. In the end I have four vials, 4 females and 4 males in each one. The flies are looking great, and I go home for the weekend feeling good.
On Monday I returned to tragedy. In one vial what I had initially identified as a female yeast crawl turned out to have actually been a chad male in disguise and he had been very busy with the three ladies, so that vial and its flies was no longer usable for the experiment. That would have been fine, if it were not for the fact that two of the other vials had died. So, im down to one vial and I email my professor because im not sure if one vial will be enough to get the end result of 500 second generation flies.
Three days and three unanswered emails later, the one surviving vial has a mass death. There are now only 3 surviving flies, 1 yeast crawl and her two boyfriends. There were no signs that the flies had mated.
Long story short, I was very unamused with my professor's inability to respond to my emails for days straight, however I was eventually able to talk with him and he has made me some new vials with healthy flies, which now two weeks later I have recived! They all seem to be doing good. Me and my proffer think what happened is that the bar eye flies had gotten infected with something, as the original batch of bar eyes I was given also had a lot of die off happen in it.
As for the one remaining original vial, great news! They eventualy actually successfully mated, and their children have emerged as adults! The two guys didn't live long enough to meet their kids, but mama yeast crawl did and is a very proud parent.
(Rip Wonky-Wings and Fat-Butt the male bar eyed fruit flies, your progeny have survived against the odds, and soon will have more flies join their ranks from the new vials.)

So over the course of the last week of being the god of my wingless fruit fly civilization called Yeast Crawls i've learned something verrrry interesting about fruit flys and the different mutant strains. But first, let me tell you a bit about how you handle your flies.
You see, fruit flies are small. really small. So small you usually have to look at them under a microscope to really see anything about them. Unfortunately, fruit flies have this tendency to skitter arround and even fly off sometimes, which is not condusive to inspecting them under a microscope. So we use ether to knock them out. Simple solution, right?
Well as it turns out diffrent mutant fruit fly strains have diffrent resistances to ether.
I found this out after first handling the yeast crawls (apterous mutation) who are very receptive to ether. You just put them in a lil container with ether for about a minute and the fall asleep, and they will stay asleep for a solid 15 minutes. so I was expecting the flies of my other mutation (bar eyes) to also be easy to knock out.
I was wrong.
Turns out bar eye fruit flies have stupidly high resistance to ether. As in "put them in the etherlizer for 10+ minutes for them to finaly go down, take them out to put them under a microscope, they're already getting up and trying to fly away in 30 seconds" resistant to ether.
So yeah these lil flies with smaller, misshapened eyes are an absolute pain in my butt. JUST GO TO SLEEP ALREADY YOU NEAR SIGHTED NATTS.
The longer I live on this earth and the longer I spend in my genetics class, the more I think bug scientists are honestly right. These lil guys are so stupid and I love them so much.
Look at these little guys.
They're so small. They have such big, dumb, inocent eyes. They don't know that there's thousands of beings so much larger than they could ever comprehend who all think these lil flies are fantastic. They don't even know.
.... wait I was trying to write a post about cool things I've learned about these guys uuuHH-
Im sory but it only just slammed into me like a semi truck what combo you had @wirmageddon
Sepia and apterous. Wingless and black eyes.
For those of you not in the know, there are two things you look for when checking your asleep flies to see if they're just asleep or actually dead: you check if their wings are held close to their body or if they're pointed out and away, and you check their eyes because when they've been dead for a while their eyes turn black.
You had the nightmare combo of never knowing if your etherlized flies are alive or dead.

hello yes plz keep us updated on the yeast crawls
Yall I have some FANTASTIC news: today I saw the first little F2 generation* larvae. It was so honking tiny. I could barely see the lil guy.
*F2 generation means the second generation after your original parents, so basically the grandkids of your first organisms you had bred. F2 generations also tend to be very.... sweet home Alabama, shall we say, which is done to get the resessive traits to get expressed in their ofspring that was expressed in the original parents.
Oh thats a HORRIFYING addition.
Can you imagine how much yeast a cat sized yeast crawl would consume??? There would be absolutely no way they wouldn't just flat out break out in their desire for yeast, and then they'd find the local brewery and eat all of their brewer's yeast, and I live in a small university/bar city so the local government would definitely come for my head for daring to harm the beer production.
They wouldn't care about the fact that scientific horrors had been unleashed on the public tho, they'd only care about the beer.

first. Good Bot.
Second! If you ever see/hear about something existing in a binary, it's simplified (usually for teaching or political reasons).
There is no such thing as a true binary, they can not exist. It's never "yes or no" there's ALWAYS a "maybe?"

Remember, while generally true, not always.
And even in my highschool bio class we learned that biological cis men that don't have an xy, and biological cis women who don't have xx. There can be variation within their genetics
Also, how do you know what chromosomes you have? Have you had them tested?
(correct me if I used any wrong terms)
Instead of saying sex isn't real, we really need to put emphasis not only on the spectrum of sex and gender, but on the following:
Human beings have been falsely classified as sexually dymorphic for ages
Approximately 4% of the population is documented intersex and that's just what we have measured. Many people are estimated to be undiagnosed and undetected intersex, because research is coming to find that determining intersexedness or sex morph in humans is far more complicated than looking at the outside and checking chromosomes.
Doctors in majority still actively avoid, omit, and coerce in relation to intersex variations. They also tend to manipulate data to minimize our proportional population size. They will often intentionally avoid, ignore, or deny a person who believes they may be intersex, dismissing it as "rare and detected at birth".
Intersex people are as common as if not more common than people with red hair and green eyes. That is only while acknowledging what is currently measured. Many people have lived entire lives and been found to be intersex posthumously, even when they never knew it in life.
Intersex people have always been here, worldwide cultures pre-Colonialism acknowledged this openly in a variety of ways. Colonial societies also still had intersex people and there is documentation of this fact in multiple convergent cases.
Intersex conditions are not inherently disabling, and even if they have disabling properties they are not "defects" but a variation of human experience.
Intersex people are the masters of our own autonomy and physiology. We make the decisions about whether we alter ourselves or not. Nobody else.
Intersex people are not tokens to further trans liberation, not without mutual aid and real solidarity. While bringing us up to prove that binary sex is a sham IS true, more people need to actually talk about our oppression instead of leaving it at "they exist".
More intersex people are fertile/virile and have children than you think. like. Way more.
You, yes YOU could potentially be intersex and never know it. It's up to you whether that seems likely and is worth pursuing the research and diagnostics needed to ascertain the truth. Intersexedness is not always visible or superficially detectable by the viewer of an individual. Not all intersex people look androgynous or have clearly ambiguous genitalia.
A variation of genitals, gonads, hormones, chromosomes, and similar sex characteristic properties are not innate biological or physiological dysfunction. These represent variations on the scale of natural human sex variations.
There is no default binary of human morphism or sex anatomy.
Intersex people are whole at birth. We must not be altered until we are of age to give informed consent on matters of our autonomous pubarche.
Not all intersex people are detected in childhood.
There are countless ways to be intersex, and we are learning more about human sex variations every day.
The phrase "Disorder of sexual development/DSD" has served a purpose at times, but is largely used in medicalist views of intersex people. These facts coexist. This pathological view perpetuates the idea of these things being inherently defective, and is used by doctors in the pursuit of minimizing and erasing our existence. I would not fault an intersex person for calling their condition a DSD, but dyadics should be wary of how they use this phrasing, or avoid it entirely. Not all intersex people like to refer to their intersex condition as a disorder.
The claims that PCOS can't ever present as "really" intersex are largely claims that come from dyadic bias or medicalism, not from the intersex community. PCOS and NCAH (which is undeniably an intersex condition) are so similar that most late diagnosed NCAH intersex people like myself mistakenly believe or are told they have PCOS first. PCOS that presents with hyperandrogenism is intersex, if the individual wishes to seek such community.
Intersex people would net gain more from normalizing that there's more of us than we realize, and that we are whole as we are born, than we gain from the view of our existence as a pitiable and incomplete disorderly state.
Intersex people choose our own identity and gender, like anyone else.
Intersex people benefit from the normalization of varsexedness, which is why we must show solidarity with the trans community, and the trans community should show the same in return.
If you do not have reason to believe you are intersex but identify with the alignment of intersexedness, you may identify as varsex! Intersex conditions are congenital and one cannot "become intersex", whereas varsexedness is an umbrella that covers intersex people and trans people of various sexes together.
Humans are sexually omnimorphic. Say it with your chest and support intersex people. Happy pride month y'all.
💛💜💛
