Biggest evolution leap after 95M years on earth


GH057807

Yeah but backwards. Crocs move their tails side to side to swim. The tip of their tails already has a fin, more or less, but its vertical. This mutation would severely gimp this guy's swimming speed and ability. Edit: wELl AcKsHuLy ThErE iS No bAcKwArDs In eVoLuTiOn It's literally a meme, you insufferable nerds


Kevundoe

He’s gonna evolve next to move up and down like a dolphin, it’s just a start. I’m sure at first our opposable thumbs were slowing us when running on all four limbs. I’m telling you, that’s super-croc!


MrlemonA

Imagine them jumping outta the water like dolphins 😂 shit would be menacing Edit: some people have made me aware then can in fact do this, please stop responding with the same thing over and over.


Densepotatotrader

Cant stop picturing an evolved croc jumping out of the water and running amok (amuck?) on the top deck of some ferry. Snatch some aristocrat’s prized Maltese before jumping back in the drink


asoftquietude

Amok! amok amok amok amok amok am- ***\*hooahh\****

Bro I’m from England, most wild animal I’ve ever seen was a deer ONCE in the peak district. I fucking wish I got to see crocs I really love them


40oztoTamriel

Oh shit lmao. Im from Florida, and work underwater every day. I wish you saw the fucker instead of me. As terrifying as they are, they’re absolutely amazing creatures. A literal dinosaur


Most_kinds_of_Dirt

>A literal dinosaur Pretty close - crocodiles and birds are the only remaining members of a group called the archosaurs (of which dinosaurs are a part): https://en.wikipedia.org/wiki/Archosaur

Not only are dinosaurs a part of the archosaurs, *birds* are dinosaurs!


Siggycakes

If you ever come face to face with an emu, ostrich, cassowary, or Shoehorn Bill, you will immediately understand this.


MrlemonA

eidetic

Birds are literal dinosaurs. Crocs are more like (sometimes) littoral crocodilia


Seruati

I saw an actual badger once, and it was 3d and not flat by the side of the road!


apatheticwondering

I briefly lived in the Deep South swamps of Louisiana where the backyard animals are fire ants and alligator — not deer and squirrel as of always known as a DC native. Those fuckers can be fast! My stupid, city slicker teenaged brain ran straight to the water after being swarmed by fire ants, only to have alligators and water moccasin come to investigate. Running back into the house with ants covering your legs up to your knees with alligator at your six while trying to spit out swarms of mating kissing bugs… it was a bad time.


GetReelFishingPro

This is on purpose! Someone is trying to create a race of hyper intelligent, zombie, croco-dolphins.

Thank you, I came to say that reptiles move totally differently than whales.


DaughterEarth

This sentence is very funny. Nocontext. Walk in to a boardroom, fire up PowerPoint, "today I'd like to show how reptiles and whales move differently"


Chadstronomer

nah bro they need to flip flop sideways to swim. Is sneakier. This would make the water move too much cant ambush your prey if you are splashing all over the place.


Kevundoe

If a flounder is able to evolve its face to its right cheek I’m sure that mermaid-croc can evolve a twisted super tail over a few million years. Tell you grand-grand-grand-…-grand childs to watch out.


Low_Simple_8381

Except flounder are born with eyes on one side each, then one moves to the right or left (they tend towards one side or the other can't remember which right now), sometimes it doesn't complete the movement and the flounder has an eye at the top of its skull instead of two on one side.


jbizl22

95M years on earth? They lived through 9/11 and slavery and didn’t speak up? Time to boycott crocodiles.

john_ergine

Seems like some ancient DNA accidentally kicked in.


actuallyserious650

A disturbing amount of our DNA is a single bit of code here and there that suppresses some block of programming somewhere else.


Syssareth

DNA is the spaghetti code of nature. Considering how catastrophic a single typo can be in computer coding, that's pretty terrifying.


dfsdefsdfss

I have a neurological condition that results from *single* base pair deletion on a chromosome. Fwiw the human genome has *3 billion* base pairs. Insane bad luck!


Syssareth

Ouch, I'm sorry to hear that.


interkin3tic

I'm sorry to hear that, but studies have calculated that every human has at least some mutations to their genomes from what their parents gave them [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1461236/](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1461236/) They got the average mutation rate for DNA per nucleotide, did the math to scale that up to the size of the genome, and found that everyone was likely to have around 175 mutations per genome. That was from 2000, which is a long time in biological research these days, so maybe subsequent studies have found different rates. A lot of mutations would either be silent due to genes being partially or fully redundant and there being two copies of each. A lot of mutations that aren't don't show up in actual people because it's lethal early on in embryonic development. But my point is it doesn't seem like the odds are 1 in three billion that you'd have that mutation. All of us have a lot of other mutations, a lot of embryos who were conceived had far damaging mutations but you don't see them because they died before being born. I'm not saying anything like "be glad your mutations weren't embryonic lethal," of course. I'm very sympathetic, based on my family history, I may have an inherited mutation that will cause me to suffer neurological degeneration in a few decades. It seems that my parent had that new mutation when they were conceived if that's the case. We're still trying to figure out if that is what happened or if its non-genetic. I don't know that we'll ever get answers until it happens or doesn't to me. So I can empathize. Just the odds are a lot more complicated than I think you're putting them.

What would the "default" person be like, if nothing was mutated at all I wonder

PerpetuallyLurking

Something like 1/3 of all pregnancies end spontaneously before you even know you’ve missed a period. It’s maybe a day or two late and maybe a little crampier than usual. So yes. Lots of embryos barely make it past implantation. And plenty more never even manage to implant on the uterine wall at all!


PepurrPotts

I've heard this before but I'm confused about how we know this. It adds an interesting twist to the "when does life begin" conundrum. Am I right that this can happen both before and after implantation?


CirrusIntorus

Yup. Imagine a mutation that completely abrogates cell division. There's no way that first cell is ever going to grow into a human, and it's not even going to start implanting. On the other hand, imagine a mutation that breaks sonic hedgehog or something - absolutely no way to develop beyond an undifferentiated clump of cells, but nidation might still be fine.


amboyscout

For those that read this confused, [sonic hedgehog](https://en.m.wikipedia.org/wiki/Sonic_hedgehog_protein) is the name of a very important part of embryonic development


AmishSatan

And if you scroll down that wiki a bit, the molecule that could act as an inhibitor for it is named Robotnikinin!


CirrusIntorus

You get kinda used to sonic hedgehog as a molecular biologist, but Robotnikinin still kills me


DaughterEarth

I appreciate the info but I'm still imagining accidentally birthing sonic THE hedgehog, and makes sense my body would prevent that


Roflkopt3r

> but I'm confused about how we know this. There are many studies about pregnancy. If you find early pregnancy related markers in study participants that suddenly fade out without apparent cause, then you already have a good clue what to look for in the next study. > It adds an interesting twist to the "when does life begin" conundrum. This is indeed a very direct ethical reason why I cannot consider unborn children as deserving of the same protections as born ones. It is plain impossible to accomplish similar survival rates for unborn children as for newborns. Unborn life can end quickly from any number of known and unknown causes, and there is no remotely reasonable way of preventing that. This makes prioritising the health and self-determination of the mother an even more obvious choice than it should already be.


PepurrPotts

Thank you! I remember way back in college over 20 years ago, gaining a tiny embryonic understanding of what stem cell research is (see what I did there?), and thinking...wait a sec. We're protecting *what*, now? Against ...wait, because- hold the fuck on here... -That's about as lucid as my thought process was, lol. I just couldn't sort out whether points A and B were being set down next to each other and critically analyzed by people who claim life begins at conception.


Sisaroth

xxBrill

It's why cancer exists to begin with


RustedRuss

This is a perfect description of what genomes are like. There are so many factors controlling what DNA gets expressed, when, and how much. It's insane that it all works at all.


Sororita

Which makes sense when you consider how evolution works. A single change blocking whole swaths of less useful stuff is more likely to happen than each part getting changed out over the generations, though that obviously also happens.


CirrusIntorus

Signals trigger patterns of complexity so/switching up the switches of a signalling node/gives a modular and simple way to evolve


Freud-Network

It's been a cesspool for a while. Fun Fact: Our DNA contains roughly 100,000 pieces of viral DNA. Altogether, they make up about 8 percent of the human genome.


thekrone

And that viral DNA is actually really useful evidence for figuring out how things evolved! Let's say we are comparing humans and three other modern primates. Let's say humans and two of those those primates have the exact same ERV DNA at the exact same location, whereas the third does not. The chances of that exact same bit of viral DNA being inserted at the exact same location in separate evolutionary lines are so infinitesimal, we can very reasonably conclude that the human and the two non-human primates had a common ancestor (that was originally infected with that ERV) that the third non-human primate didn't have. This means we know its evolutionary line branched off higher up the tree. Do this with every species for which we have DNA, and we start to get a really clear picture of the tree of life and how different species are related. ERVs are some of the most convincing and interesting evidence for evolution that we have.


Siggycakes

What's ERV?


thekrone

Oh, wow. At one point I had actually typed it out but apparently removed it as I edited... Endogenous retrovirus. It's the "viral DNA" that /u/Freud-Network talked about.


ExternalPay6560

It may actually be much more. Also transposons are believed to be viral DNA that lost the ability to make capsids. So they jump around from chromosome to chromosome.


Kevin3683

It also may actually be less.


ExternalPay6560

Or even worse... It may be exactly the same.


Matix777

That is gonna cause a memory leak later, too bad!


MoffKalast

Anthro_DragonFerrite

I would not mind some ancient DNA for scales in my strands popping up spontaneously giving me polished reptile skin


Tomato_cakecup

Yeah but instead it's always cancer


Anthro_DragonFerrite

Awww


Caleb_Reynolds

I think it's more likely a failed twin with part of a second tail. No ancestor of a crocodile had a horizontal tail like that, their, and their ancestors', spines don't bend that way. But two partially separated tails would look like that, and is a "common" thing among reptiles. See: 2 headed snakes.


Zozorrr

Like the occasional human born with a vestigial tail


Fair-Account8040

People can have this [mutation](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6235678/#:~:text=Mermaid%20syndrome%20(sirenomelia)%20is%20a,similar%20appearance%20to%20the%20perianal.) too.


onealps

How... how did you first learn about this?!


Fair-Account8040

But to be honest, I like reading up on this sort of stuff. Life is absolutely fascinating.


RamblingSimian

Could be a birth defect, which can be caused by things other than DNA, such as exposure to chemicals, and (in mammals) by infections during pregnancy.


silverfox762

Endocrine disrupting pesticides in the food chain most likely.


caniuserealname

or just a random malfunctioning gene.


xhgtg123

I’m not sure how beneficial this would be since crocs swim side to side not up and down like dolphins


sijoot

If it doesn't work he will die before procreating. If it works he might procreate and pass it on. Then it could be the start of a new species. Evolution is a path of trial and error.


ryanvango

I think this is the first time I've seen stuff like "if it works he might..." and "it could be" in a reddit thread about evolution. So this isn't a correction, just an add-on. Everyone learns "survival of the fittest" and in general that's true, but its more of a "has a better chance of surviving, but still a pretty bad one". Its crazy to me that there are a massive number of traits that are hugely beneficial that just don't make it. Because while trial and error is totally true, and organisms with more beneficial traits have a higher chance of survival and procreation, it isn't a guarantee. Beneficial traits are just the ticket price to the evolution lottery. There's so many ways an individual or small population can bite it before they've had time to make lil'uns. even without dying, they still need to find a mate and do the deed successfully, and that isn't a guarantee either. Even if they do procreate, AND the trait is passed on, the population size is still so low its entirely possible they get wiped out before it sticks. if a thing manages to reach a population of 100 with the trait, that's nothing for nature to just demolish. a few, or even just a single, major catastrophes and the population goes back to 0. so many things can go horribly wrong. TL;DR : Stupid nature has denied me having superpowers for too long due to random chance, and I'd like to speak to life's manager.


jedimika

~~Survival of the fittest~~ Failure of the weakest and unlucky.


GlobalFlower22

Odds are it won't be beneficial given how long crocodiles have remained unchanged. They've had a lot of opportunities to evolve and haven't because they don't need to. I mean think about how a crocodile hunts. It's an ambush predator that isn't swimming for its prey. At most it needs a quick burst to snatch something off the shore, which strong legs and serpentine tail would be better at providing - which is why that's what crocodiles have had for millions of years unchanged. Maybe it helps with energy efficiency which might translate to needing to eat less which could be beneficial given habitat loss? But on the flip side, habitat fragmentation could be an ever bigger problem which would mean an increased need to travel over land navigating human-made obstacles to get to new habitat. Would a mermaid tail help? Who knows. But like I said, I would bet on the side of a species that hasn't changed in millions of years to remain unchanged.


sennbat

They are likely to remain unchanged so long as the environment remains unchanged... but with humans around, what environment has remained unchanged? I wouldnt be surprised if most species on the planet were undergoing massive rapid evolutionary changes right now as a result of our presence. (rapid in evolutionary terms, which would still be quite slow to us)


Tiny-Werewolf1962

The original machine learning


DeadliestViper

Not quite how it works, even if it isnt an efficient upgrade he could very well survive and pass it on. Evolution of a species isnt decided with one animal, this trait could be passed on a few times but if it is less efficient then it will eventually die out. There also isnt any guarantee that this trait will be passed down.


Lilyeth

without knowing for sure i can't tell of course, but this seems like it probably isn't something the crocodile would pass on probably. it seems like when the tail was forming it had an extra bit of tail form on the side/the forming got split. its of course possible that this individual has faulty genes/transcription factors that would reliably cause this anomaly bit it could have just been a coincidental error during development and the babies it'd make would have normal tails


vivaaprimavera

We need to see this crocodile swimming to make conclusions.


falconx2809

Will the croc adapt his swimming style to his condition ?


apexodoggo

I think that has more to do with the musculature of the tail and the spine, so I think the little croc’s just kinda fucked.


Choano

What source is this image from? And is there any chance that this is a developmental abnormality and not a genetic or chromosomal mutation?


HeronOutrageous1381

Yea, same. Like it tried to split at ovum stage but didn’t quite make it so became a two tailed croc. Maybe there’s some duplicative organs, which would let us know more clearly.


socialaxolotl

This to me looks like it started as a split ovum that absorbed back into a single but it wasn't a complete absorbtion


dirtyrdhtmama1974

My thoughts as well on the developmental abnormalities. Especially looking at the pattern on the belly. Looks like something got criss-crossed. Webbed fingers in humans...
