#not sure how to feel about this thing i sometimes do. where im talking to ppl and im there in the moment but im also standing in a future #where they are gone. dead or otherwise absent from my life. speaking to corpses not yet dead. and part of that is probably that my mom had #cancer for 10 years and at the end you could see she was dying but i live far away so in the time between my last seeing her and her dying #it was all anticipation of death. part of it is that i listen to so many stories about dead people and have lived enough life to kno u can #go unceremoniously at any moment and there is no good way to go. and part of it is that i am afflicted by visions of myself and others dying #awful deaths. but i dont kno what to feel abt it. i don't think it changes how i behave. outside of not wanting pets bc all i can think abt #is dealing with a dead animal. it just gives me a sense of disconnection i guess. but then ive always felt not quite in sync. maybe i just #feel it more now while im home bc childhood associates see a past version of me and dont see interested in investigating thr person i #currently am. but then y should they when I'll just be gone again. maybe its also that im at a time in my life where ill prob move at least #2 more times and i dont kno where ill end up. and i haven't historically brought friendships along in the moves. so theres a constant sense #of moving toward and end point. and i suppose thats life. and i dont resent that this is how life is but im not sure how to feel aboutalways #standing at the edge of the universe. i tend to hold tight to painful things until they stop hurting but then the feeling drain away until #everythings boring again. probably ive just dulled myself to something that used to frighten me but the idea still occupies a space in my #head. i dunno. sometimes it happens in reverse too. someone says something to me and im there but standing in a future where im the one whos #dead. and im apologetic for existing as a void. but so it goes. standing living and dead. already gone #unrelated

:-P

Bruh. My dad is learning to vlog.

#he watchs a lot of bike packing videos on YouTube and wants to give it a try #he has like zero computer skills tho #bc hes old and my mom was a tech person so she would get annoyed and just do all the computer stuff #i wonder if i kno more computer stuff than her now. probably not. she could code in some old language no one uses anymore.#i just do bioinformatics stuff. but i kno enough to figure things out #anyway. i guess i forget that basic computer skills are actually a skill. i mean. the basic computer things undergrads refuse to figure out #boggles the mind #unrelated

#i fucked the colors up on the dragon one 🥲 this is the problem when u dont have a color plan #i saved it a lil but its still fucked and im not redrawing it #tw blood #dragon #bbc merlin #merlin emrys #arthur pendragon

I've seen at least 3 ppl in various places get angry about astrophage dividing by mitosis and insisting it would divide by binary fission. But, given the mitochondria, astrophage is a eukaryote and it is possible for single cell eukaryotes to divide via mitosis...

#maybe im missing something idk. but my guess is that most ppl on this site have a high school or undergrad understanding of biology.#and things are often more complex than what u learn in a classroom setting #but whatever. im being an intollerable kno it all 🥲#unless im just blatantly missing something. i read the book very fast. some would say too fast #and that's bc i hated it... but i do love biology a lot. and thinking hard abt things that dont matter lol #phm

I am once again asking for art requests 🙏

#can be anything. any show. movie. landscape #location. vibe. idk whatever #do i still have the line arts uncolored from last time i did this? yes. but im gonna work on today. so they will be posted eventually #im just in an art slump :-( probably bc im not super obsessed with any one thing rn 😔#unrelated

:-P

#i think this is the most i fucked up the lines and refused to redraw. i think i fixed it ok #i made his eyes way too close together and messed up the nose and mouth #i probably couldnt fix it if he wasnt albino. thank u white gelly pens #srry i dont post much lately. ive been busy and didnt want to color 😭#naruto #dragon #senju tobirama #ugh. i should get a actually scanner. i nver try to find good lighting so everything looks terrible

Why astrophage having a mitochondria is so silly.

Andy Weir asserts that astrophage has a mitochondria (not something mitochondria like, a streight up mitochondria), which is 98% similar to those on Earth. To which mitochondria on Earth? Unspecified. But you can find like 70% mitochondria similarity within a single class of organisms (diatoms). So it's EXTREMELY similar to something.

Before we do this you should know that Earth is something like 4.5 billion years old. Life may have existed on earth as long as 4 billion years ago. And you can split life into two categories: bacteria and archaea.

Widely accepted history of the mitochondria: The mitochondria is an example of endosymbiosis. Maybe 1.5-2 billion years ago, an archaea consumed an alphaproteobacteria and did not destroy it. These captive alphaproteobacteria were passed along from mother to daughter cell. Over time that alphaproteobacteria started being used by the archea for energy production and it's genome degraded enough that it could be classified as an organelle which we call the mitochondria. Probably in part due to the function of this mitochondria we get the rise of complex multicelluarity in eukaryotes.

So if we assume astrophage came from earth: The first cells escaped earth's atmosphere less than 2 billion years ago (wtf they were doing on earth that allowed them to thrive in the vacuumed of space who tf knows bc apparently there's nothing remotly like a metabolic precursor on phm's earth), developed space travel capablity and completely deserted their system of origin (given we apparently have no non-star consuming astrophage in our solar system), started eating suns, and returned to the Sol system to cause problems. Evolution doesn't happen in a vacuum, the fact we seem to have no context for astrophage to have arisin in is very weird and doesn't really make sense but makes more sense to me than the alternative...

Which is, panspermia which Andy Weir seems to want us to believe. But then we have to accept that the early 2 billion years worth of bacterial and archeal life all traveled through space to get to earth. That's a lot of nonspace fairing microbial biomass. It doesn't make sense. Unless earth was intentionally seeded ~2 billion years ago, which is not what anybody in the book seems to be implying.

Then there's the whole astrophage produces too much energy for ATP to hold so why does it even need a mitochondria? And the fact it has a mitochondria implies it's using aerobic respiration out there in the vacuum of space given that single celled eukaryotes living in low oxygen or anoxic conditions tend to have reduced mitochondria or lose it completely. And I would say that maybe the astrophage mitochondria is most similar to these anarobe mitochondria but that would probably significantly shorten the timeline for when they left Earth and the implication in the book is clearly that they are your standard, functional mitochondria.

All that to say, when I read that astrophage had a mitochondria is was like: What the fuck do you mean it has a mitochondria?

The mitochondria can be an astrophage’s vestigal organ(elle). It’s not uncommon for organisms to retain organs despite evolving past the need for it (see: appendix [mostly], coccyx, wisdom teeth, etc.)

Also, Weir can also be arguing for convergent evolution. Who’s to say the bacterial precursor to mitochondria couldn’t arise independently across various species? And that last 2% difference in mitochondrial structure may play a bigger impact on the overall function of it inside the Astrophage. Even one difference in the structure could potentially create radical difference in function. Just like how two sets of DNA may be incredibly similar, but the difference in what constitutes the coding/non-coding regions due to slightly different mutations may lead to a significantly altered protein product when transcribed.

(One last thing regarding the tags on OP’s post: mitochondria are relatively recent things but so are astrophages. It’s not really explained afaik how the astrophages have come into existence, so you could speculate that there could perhaps be a common ancestor.)

TL;DR - it’s sci-fi lol

Retaining an organelle in a single cell organism is a bit more tricky than retaining an organ in a multicelluar organism bc I /think/ single cell eukaryotes have a stronger deletion bias than multicelluar eukaryotes. So it tends to be "use it or lose it". As I said, in single cell eukaryotes not using their mitochondria tend to lose it or it's functionality is degraded. And if you want to be generous, you could read that as what he meant but its certainly not what he implied

As for convergent evolution, this the evolution of similar physical traits in distantly related organisms as a product to occupying the same niche. The strategies to produce these physical traits are very very different at the sequence level. Though, I'm sure there are some where they do an identical deletion or something to produce the effect but i imagine those situations are in the minority if we are talking distant relation. Even in a single genus, if I look at two strains of bacteria that have a couple million years separating their split, if they have the exact same sequence in a fairly large gene but the strains between them dont, the assumption will not be that they converged on the same sequence, it is that horizontal transfer happened. That the sequence in one came directly from the other. If alphaproteobacteria evolved twice to have a nearly identical genome sequence to that on earth, was consumed in the same way as on earth, degraded as an organelle to be 98% similar to earth mitochondria. It would be so unlikely, I would be forced to consider devine intervention

#but youre right. i could do the work for andy weir and make his lack of knowledge make sense but unfortunately im thr type of loser who #like to take thinks literally where i so choose and to poke holes in things. thats how i have fun #im not even saying the mitochondria thing was a bad choice. i mean it is if you want credibility as a hard scifi writer but its like the #only thing i liked abt the book. its so silly it delighted me #reblog #phm #project hail mary
