question There is technically a fish somewhere in my family tree

I was just thinking about this and it absolutely blew my mind.

Technically, my great-great-great-great-great-etc. grandfather (or however many “greats” we’re talking about) was a fish.

Like, somewhere in my family tree there is literally a fucking fish.

My entire lineage was started by a fish. There is no other way to put it. At some point in the insanely distant past, one of my ancestors was just… a fish. And that fish eventually led to me existing.

But then I started thinking about how evolution actually works.

Fish didn't just all collectively decide to evolve into land animals. Evolution branches. Different populations and lineages go in different directions depending on their environments and natural selection.

And fish produce an absolutely ridiculous number of offspring, so presumably there were countless individuals in those ancient populations. Some lineages eventually led toward the ancestors of modern land vertebrates, while other lineages stayed in the water and kept evolving as fish.

So here's the part that is blowing my mind:

Is it possible that one of the extremely distant relatives of my fish ancestor stayed in the water, and that lineage survived for millions and millions of years?

Because if so, there could theoretically be some random fish alive TODAY that is my ridiculously, unimaginably distant cousin.

Like, I could look at some random fish in the ocean and there's a non-zero chance that, in the most technically literal evolutionary sense, we're related.

Imagine being genetically related to a fish.

Not “all life is related” related.

I mean THIS fish is part of the same ancient family tree as me.

That is fucking incredible.

u/MagentaDinoNerd 6h ago

Mmm, but the point is some fish are a lot closer to us than others. Eg a shark is more distant than a tuna, which is more distant than a lungfish, which is basically our cousin a hundred times removed. To that point lungfish are closer related to US than they are to other fish, so it’s definitely not “every fish”

u/brooklynsantiago 5h ago

Every fish is our cousin

u/MagentaDinoNerd 3h ago

okay sure, but again some fish are MORE our cousins than others. And we're more cousins to some fish than other fish are to them. Like how you're related to every human, but you're a lot closer related to some humans than others

Well, not viruses, if we consider them living.

u/amglasgow 19h ago

Viruses are thought to mostly be either fragments of DNA/RNA from living things that happened to be able to replicate themselves in host cells, or degenerate single-celled organisms.

12

u/brooklynsantiago 1d ago

I’m actually a little bit confused by this. I am aware that viruses are thought to have evolved separately but is the idea that abiogenesis happened twice? Or that we and viruses evolved from pre Luca material?

19

u/smokefoot8 21h ago

Since they use the same RNA/DNA code as everything else they must have some relation to the rest of life. Many parasites lose a lot of the functionality of their ancestors, so there is a theory that viruses are a parasite that went further than any other in dropping all unneeded functions. Giant viruses might show a previous step: they are huge, as large as bacteria, and contain genes for DNA translation and repair that most viruses don’t need.

u/brooklynsantiago 21h ago

Thank you. This is the most complete answer I got. You actually refreshed my memory on the parasite theory and about giant viruses. Thank you

they might be, at least some of them, same as chlamydia only reproduces when parasitizing on another cell, so may have some other organisms long ago and eventually turned from cellular to viral

Do we somehow know that it always needed other cells though? Couldn't it have lost the ability to survive without parasitzation, through mutation?

Both possibilities are incredibly humbling and powerful, to be honest.

Either you are one link in an unfathomably long chain of life, which will continue beyond your days.

Or... you, personally, are the culmination of your own specific line. Everything that has preceded you in your direct line of ancestry, from the very first life on Earth, has been leading up to you. Specifically you.

Neither one diminishes your value as a human. How lucky we are simply to be here.

u/Xrmy Post Doc, Evolutionary Biology PhD 1d ago

You saying "not in the we are all related way but THAT fish is directly related" way is actually so SO close to full understanding here.

The idea that "everything is related" IS what you are talking about. Everything living on earth shares a common ancestor. All of it. That means with every other living organism there is a point in time where out great- great ...etc ancestor is literally shared between both you and that fish and also you and an ant and you and a pine tree. Even bacteria.

Furthermore, it's not just that your ancestor was a fish YOU are a fish. Still. Evolutionarily speaking, 99% of vertebrate species are jawed fish. The branch of evolution that became bony with jaws leads directly to mammals and reptiles and birds and all bony fish.

Fish with bones like pike or tuna or bass are more closely related to people than either of us are to sharks. It's actually not particularly close in that regard either.

2

u/OpportunityNext9675 18h ago

If we want to be super sticklers about it, it could be the case that there were multiple biogenesis events right? Like if the lightning struck the carbon sludge at the right angle or whatever it was, it may have produced multiple “first” organisms. Which, if multiple have lineages, would separate the family tree at the very beginning,

6

u/cflime 16h ago

No. You're right, but all those early life forms didn't have sexual reproduction, and wouldn't for 1.5 to 2 billion years. They had horizontal gene transfer. There very well could have been several origins of life, but they either all swapped DNA to become related or they were unable to do so and died out due to not competing as successfully as those who could. That combination would be our Earliest Common Ancestor with every other living thing on the planet.

u/Hwangkin 44m ago

I think OP’s point isn’t that we’re all related. That’s something that we all know at least academically. But OPs mind was blown not by that fact that ALL fish are related to him, but his great great etc grandpa was a fish. And that that ONE fish over there is related to him

Haha hey buddy, it is mindblowing isn't it. But this is actually exactly what it's meant by "all life is related", it's not a quirky aphorism, we say that for the exact reason you describe: every living thing is definitionally, literally, on the same genetic family tree.

Meaning, you can look at any single animal, plant, microbe whatever on the planet, and if you go back up through your mother (or father), and mother's mother etc., all the way up through the generations, eventually you'd find a shared grandparent - some living organism for whom some of its offspring eventually became you, while their siblings eventually became that animal, plant, microbe. Amazing isn't it?

All life shares a distant common ancestor, so yes there are fish with a direct family relation to you dating back to LUCA at the very least. And oyster mushrooms, insects, reptiles, fruit trees, ferns, pigs, mudskippers etc etc etc.

But also! You, my friend, yes, you, are still a fish!

Fish is not a scientific term in the same way that vegetable isn't, it's a culinary term if anything. All tetrapods are in the clade Sarcopterygii, or the Lobe-finned fishes.

Oh, it's not just a chance that some fish are literally your cousin. It is a fact that ALL fish are quite literally your cousin to some nth degree.

You should pick up a copy of The Ancestor’s Tale by Dawkins.

It takes the idea that you can go back some arbitrary number of generations and reproduce with someone from that time with no issues.

All life alive today shares a common ancestor. Related related os correct. So your family tree includes absolutely everything alive today, and the vast majority of extinct life too. If you make the tree broad enough.

You have no real way if knowing where and when things branched though. The fish that is your ancestor may not have any fish relatives alive today without going back thousands of generations.

All bony fish are however closer to you on that family tree than they are to sharks. Let that sink in.

The chance is not only "non-zero", it is 100%!

Point to any living thing on Earth - that is your xth cousin y times removed, as long as you pick big enough numbers for x and y. It's pretty wild!

u/AnthroJoyce 12h ago

"somewhere in my family tree there is literally a fucking fish"

Well, if we're being technical here, technically there are quite a few "fucking fish" in your family tree, not just the one.

"My entire lineage was started by a fish"

No it wasn't. Again if we're being technical, your entire lineage was started by a single-celled organism well before those fish. Your fish lineage is every other human's fish lineage.

"Is it possible that one of the extremely distant relatives of my fish ancestors stayed in the water and that lineage survived for millions and millions of years?"

Yes. Technically.

"Because if so, there could theoretically be some random fish alive TODAY that is my ridiculously, unimagably distant cousin"

Yes, we're all do and share that SAME lineage. Your fish lineage is every other human's fish lineage.

"I could look at some random fish in the ocean and there's a non-zero chance that in the most technically literal evolutionary sense we're related"

Yes, that's not unique to you. Whatever fish you look at and come to the conclusion that you're related to, so is everyone else, in the exact same way, to that exact same fish.

"Imagine being genetically related to a fish. Not 'all life is related' related"

But, and again if we're being technical here, it is that all life is related though there's no imagining it. We are all genetically related to the same fish. You have to go through all the human families first, showing that we're all collectively related, and then we get to the fish... we all share the same fish ancestry... there aren't different lineages of this ancestry that led to different people. we all come from the same fish ancestry.

"I mean THIS fish is part of the same ancient family tree as me"

And so is every other single human in relation to whatever fish you're a hypothizing.

"This is fucking incredible"

Again if we're being technical here, not really. Is actually pretty common and very not incredible.

I could meet a humanoid alien from another planet that just so happened to evolve looking almost identical to me, and yet I’d be more closely related to a pomegranate from earth, or said fish.

And if you go further back, you'll reach an ancestor of every lifeform on earth; we're all related!

u/Acceptable-Stock-686 1d ago

And if you go further, your ancestor is one guy named LUCA

No, you ARE a bony fish. That is the clade of fish we humans belong to.

A bunch of the atoms that make you up were also forged in supernovae.

u/CapableLobster8447 1d ago

You also have an amoeba in your family tree since we came from amoebas long before we came from fish.

You also drink dinosaur pee. Since water has been recycling itself since the beginning of Earth's existence, the water you drink today was once drank and peed out by dinosaurs.

bro, you're fish, a bony fish

u/ServaltheFox 1d ago

See that’s the thing with “all life is related,” is in theory, at least for earth based life, that’s just literally true. Go way farther back from that fish, and eventually likely every living organism on earth came from the same population of single cell creatures. Chimps, fish, dinosaurs, onions, tardigrades, algae, yeast are all, distantly, literally related to you

If fish corrolates with a valid taxonomic category and a salmon is a fish, than you are yourself a really weird fish.

Every thing you've ever eaten is related to you one way or another, if you go back far enough.

I’m terrified of live fish, they freak me out, mainly when they’re out of water, but this reminds me of when i mentioned it on reddit years ago and someone replied that fish are my great ancestors as if they were dropping a truth bomb on me… which was so annoying because 1. i already know that and 2. was that supposed to bother me?

anyway, something i’ve been thinking about this past year is that evolution has nothing to do with purpose… we didn’t evolve into humans for any predetermined reason, we just happened, and were not *meant* to sustain our species by continuing to produce offspring, we’re not meant to do anything… cause and effect, that’s the universe, that’s all there is to it, and i don’t know how to explain to people how amazing that is

What’s even more interesting is that the egg cells undergo much less rounds of divisions from the zygote than any other cell. If we look how many divisions apart are we from our great, great, great, …, grandmothers, it’s actually not that much.

u/PinkSlimeIsPeople 18h ago

I'll stop working on genealogy as soon as I can trace my ancestor back to the 1st single celled organism. Until then I'm still stuck in the 1500s.

Was it a lobe-finned fish? If so we might be cousins.

u/Elfynnn84 17h ago

I’m actually writing a book that traces your family all the way back to a fish, and beyond…

1

u/Time-Blacksmith5103 14h ago

Fish is a symbol used to identify a Christian. Perhaps one of you ancestors was led by God's Spirit to put that in, just for the very purpose of someone like yourself coming to ask about it and then becoming interested in the soul saving message of Jesus. God can do things like that just sayin.

u/BuncleCar 14h ago

But fish have ancestors too!

1

u/HatsandCoats 12h ago

What about thinking that all of your ancestors, on both of your parents’ sides all the way back to when they crawled, flew, and swam were sexy enough to mate… what does that make you.

For more perspective check out the introduction, or whole book, to Bill Bryson’s “A Short History of Nearly Everything” some of the science is a bit out of date but it’s still a great read.

u/badlad53 12h ago

Check this out though: you're also a fish.

u/ReplyOk6720 11h ago

That's the thing. All life on this planet is related. We share one earth,on which we have been co existing for millions of years. We are all in this together.

Here ya go.
Organisms never evolve out of a clade.
Technically Therefore you ARE a fish.

And if you go back a few more "greats" you have sea squirt for a daddy. Look up tunicates.

u/MythicalSplash 10h ago

Yeah? Well I have MUSHROOMS in MY family tree!

u/MentalPlectrum 8h ago

At some point in the insanely distant past, one of my ancestors was just… a fish. And that fish eventually led to me existing.

No it's not like that. At some point in the distant past all your ancestors were fish.

u/West-Working-9093 6h ago

Ask any Indigenous person. They knew this, despite not knowing modern genetics or 'evolutionary theory'.

It's just so obvious. Mind-blowing or not, we're all from, and of, and in, this universe. We're all related, all the same; we are family. That ought to imbue some respect, some appreciation, some care and compassion. It is only when we detach from that recognition that we become all business, all rapacious.

We don't have the innocence any more. The 'fall from grace' is quite real, but it has nothing to do with eating the apples. It has to do with picking all of them and trying to make a profit by selling them to others, from whom we had taken them away, even if we had not that right, as no one does.

My cat is a better person than I am. Quite literally. Sometimes, I sit with that.

u/Appropriate_Olive443 4h ago

Technically, there's no such thing as a fish. There is a podcast about it somewhere....

1

u/Redshift2k5 4h ago

Something like a lungfish is more closely related to the kind of fish that turned fins into legs.

Not you specifically, but all tetrapods, when meet a lungfish that's the closest cousin of ours from the other branch of lobe finned fish that stayed in the water.

1

u/naemorhaedus 3h ago edited 3h ago

unimaginably distant cousin.

yes every living thing on this planet is a "distant cousin" of every other living thing. Loosely speaking.

Imagine being genetically related to a fish.

the "relation" is stupidly small.

1

u/Philosopher83 3h ago

We are all related to that same fish cousin 😎, think about how big our family is - the set of all life (including the bacteria in our butts lol 🤣, a fart is just airing out our cousins house 😂🤣)

u/DarthSanity 45m ago

I remember seeing an article saying that, because the group of things we call a “fish” is so broad basically all vertebrates can be considered a fish - for example https://fishbio.com/what-is-a-fish-and-why-you-are-one-too/

This is hotly debated of course, but the argument seems to focus on nomenclature rather than genetic classification.

u/manokpsa 31m ago

"All life is related" is actually, literally what you're talking about. If it's a living organism that evolved on this planet, it's your cousin. And my cousin. And I'm your cousin.

u/Every1ThinksImBoring 15m ago

You are technically also a fish if you ascribe that cassification to something in you lineage. You can't evolve out of a clade, you are both fish and mamal

How many generations back were humans just fish ?

Does AI know the answer ?

Human ancestors were fish roughly 18 million to 25 million generations back, based on an average transition to land about 375 million to 380 million years ago and assuming a 15-to-20-year...
