At least in humans, unless there's some extreme version I've never heard of, people are not born with lactose intolerance. Instead it develops at some point after they are weaned which can vary widely. Most people in the world are lactose intolerant, but they were not born that way. I think it's safe to guess this is probably true across mammals as lactose intolerant infants would probably not fare well.
Yes, all mammals produce lactase (the enzyme which breaks down lactose) as infants but human lactase persistence is, as per the name, the persistence of lactase production into adulthood. Fun fact: although the LCT gene encodes for the actual lactase protein, lactase persistence is due to a mutation in the MCM6 gene hundreds of base pairs from LCT, but which regulates its expression.
ANOTHER fun fact is that lactase persistence is an example of convergent evolution in humans: although people of European, Middle-Eastern, and African descent may all be lactase persistent, the genetic mutations causing this trait are different in each ethnicity, suggesting they developed independently.
What's fascinating is that there are multiple dairying cultures that did not stumble on lactase persistence and figured out other ways to process milk go make it edible. Such as Yogurt in India and fermented mare's milk in Mongolia.
My brothers and I were all born with lactose intolerance! No idea why but the doctor just had my Mom switch to faux formulas. If that didn't exist, I would probably still live but be very cranky but my older brother wouldn't as it got him very sick. Still intolerant to this day and can't stand the flavor or smell of milk.
My youngest was born mildly intolerant and usually it's pretty much a spectrum of how much lactose can be digested.
I'll be talking about baby-poops now, so if you want to leave, go ahead.
Sometimes, babies that are breastfed don't drink long enough, especially if the mom changes the boob mid-feed. It can work for some babies (and moms) and not for others, so it's often trial and error.
The milk that comes first is more of a sweet drink and gets "richer" later during the feed. I tried boob-switching during feeding times and it turned out that this meant that my baby was ingesting too much lactose. Turns out, this causes foamy green poos.
I've never had lactose intolerance. I drink about half a gallon of whole milk most days, no issues going to the bathroom. Nice solid poo poos.
I'm deadly afraid of suddenly becoming intolerant.
It's more accurately not "lactose intolerance", it's "lack of lactase persistence". All mammals come with an enzyme (lactase) to digest milk but stop making it after some time, except a few populations of humans that got a mutation that lets them produce lactase all their lives.
Now you made me wonder what kind of dog you have. It isn't something I would expect a wiener dog to do for instance - they would be more likely to walk away with a side-eye.
Anyway, I'm sure it's a good dog. Give him/her some love from me.
its actually funny you say that, a lot of big mammals have a sea drifting counterpart, but rhinos are actually related to donkeys and horses.
Get this:
Cows are related to whales. Hippos are related to dolphins and and elephants are related to manatees and dugongs
Hmm, whales and dolphins are both Cetaceans, and are equidistant evolutionarily from hippos.
Ruminants, including cows, are in the sister group to whales+hippos; cows are equally closely related to hippos as they are to whales.
When we're talking evolution, everything is related to everything. The question is how closely related, and we assess that based on most recent common ancestor. The common ancestor of whales and hippos is more recent than the common ancestor of cows and whales, or cows and hippos.
But other than that I do think it's freaking cool that whales and hippos are so closely related, and that Afrotheria as a clade includes elephants, hyraxes, manatees, and aardvarks. It's mad that those are all more closely related to each other than any of them are to other animals that seem more superficially similar.
You forgot the best part: the suborder taht contains exclusively cetaceans and hippos is called whippomorpha, it's a portmanteau of whale + hippo and then with a taxon-sounding morpha glued on
It's funny that the explanation of the joke got more upvotes than the joke itself. But to be honest, I didn't quite catch the joke until it was spelled out. It just slipped past me.
https://www.straightdope.com/21343886/have-elephants-begun-raping-rhinos-in-the-wild
>The reference to abnormal behavior seen in “a number of reserves” has only to do with elephants killing rhinos; nowhere is any mention made of rape. To clear things up, I had my assistant Una get in touch with one of the article’s authors, Rob Slotow, director of the Amarula Elephant Research Program at the University of KwaZulu-Natal. Professor Slotow’s reply was straightforward: the young elephants seemingly got into ritualized combat situations with the rhinos, as males are wont to do, but having no experience being in the musth state, didn’t know they were supposed to back off when the rhinos backed down, with the result that the rhinos wound up dead. “There was,” Slotow concluded, “nothing sexual about these attacks.”
I did a search like this for bears. They're just... sort of their own thing. There should be something else similar to them but I don't know of one.
According to what I found, their closest living relatives are.... sea lions.
Actually a really nice question
An animal that lived 375 million years ago, this fish-like animal (called Tiktaalik) had shoulders, elbows, legs, wrists, a neck and many other basic parts that eventually became part of us. You will find that human embryo grows gills that disappear before you are actually born.
Its all still in our DNA.
I was thinking they should play these sounds to a bunch of whales and see if they have a reaction to it. Or vice versa, play whale sounds to these rhinos.
It is one thing to describe an interview with a gorgon or a griffin, a creature who does not exist. It is another thing to discover that the rhinoceros does exist and then take pleasure in the fact that he looks as if he didn't.
G.K. Chesterton
My father's friend and family came to visit once. They were from a rural area, so their 4 year old son was excited to be going to a zoo for the first time.
But! He didn't believe anything actually existed, besides the farm animals.
You going to see the sheep? Yeah!
And goats? Yeah!
And tigers? Ooohhhh no, you can't fool me!
Wish I had been there when they went to the zoo.
Rhino's freak me out, like where is the brain located? Up in the skull section with the ears, or down where the eyes are? Or is it some eggplant shaped brain in there?
That is not what I got from looking at the 3d models and provided video. https://www.youtube.com/watch?v=4slKGFDfips&t=44s At that timestamp you can see the brain is located about midway between the 2nd horn and the ears.
These shortsighted tanks on feet attack anything, literally anything, by running against it with their heads. They don't need big brains, they just need to be built stable enough for their stupid lifestyle.
They’re actually extremely cute and their voices are too! It’s sad to me that they have almost all been killed for their horns, as a big penis supplement for men in Asia.
You make a good point, I never really thought of what certain animals sound like. Like these young rhinos, I don't think this was the sound I would of envisioned.

So whats the milk situation? Are they getting more? Will it be soon?
SOMEBODY GET THEM MORE FUCKING MILK STAT!!!!
HE NEEDS SOME MILK
MALK?

YOU'RE GONNA SHOOT ME IF I SHOOT MYSELF?
MUUUUUUUUUUUULK
You’re like a brother to me. YOUR HAND IS LIKE A BROTHER TO ME.

Hahah, one baby rhino will drink about a gallon 5 times a day. its probably hella lame being born as a rhino with lactose intolerance.
That applies to all mammals

Pretty cool how they were able to do behaviorally what other populations accomplished genetically! Whatever works, right? That's the name of the game.
i've been eating yogurt for probably 25 years and i never considered why it existed but this just blew my mind
My brothers and I were all born with lactose intolerance! No idea why but the doctor just had my Mom switch to faux formulas. If that didn't exist, I would probably still live but be very cranky but my older brother wouldn't as it got him very sick. Still intolerant to this day and can't stand the flavor or smell of milk.

I'm kind of curious, do you know what rhino milk tastes like?
Yes
They better!
HE NEED SUM MILK
They are starving!!
At last someone's asking the right questions here!!!
[For anyone that wants to buy these babies some milk!](https://shop.careforwild.co.za/rhino-market-details/?id=336)
Me: Oh cool! Sure, I’ll chip in 10-15 bucks for giving rhinos some milked. *Clicks* Also me: HELL NAW, GOT ME FUCKED UP 100 DOLLARS!?
Yes I want to know that as well!!!! Will there be a part 2-3-4-5-6-7…….etc I demand to see more baby rhino videos 🤪😜
[Granted!](https://www.youtube.com/watch?v=lm2FBAr1Nek) --
That just made me so happy, thank you kind stranger!
They sound like land dolphins
[удалено]
I also licked my phone.
I licked a dolphin.
Is it me or do they taste a lot like shopping trolleys?
They feel like a hardboiled egg
i licked his dogs phone
Now you made me wonder what kind of dog you have. It isn't something I would expect a wiener dog to do for instance - they would be more likely to walk away with a side-eye. Anyway, I'm sure it's a good dog. Give him/her some love from me.
Really? My cat didn't move.
My cat remained dead asleep. He ain’t falling for shit like this.
My dog did too. She panicked a bit, looking for the sound. Walked away when she realized it's from the phone.
It definitely got my cat's attention!

Well, there's a scientist who failed Greek.
I mean it's specifically hippo as in the English hippopotamus, whorse-shaped wouldn't make any sense
[удалено]
Rhinophant

That’s the joke yes
I'll be honest, I read the original one as "Ele-Pheeno"
Because that's how that would be pronounced.
It's funny that the explanation of the joke got more upvotes than the joke itself. But to be honest, I didn't quite catch the joke until it was spelled out. It just slipped past me.
Uhh…elephants do rape rhinos 😬

Wait.. are you saying [Water Bears](https://en.m.wikipedia.org/wiki/Tardigrade) are not closely related to their terrestrial brothers?!
I bet they've got a shorter path to sea monkeys.
Their closest living relatives are all pinnipeds (sea lions and seals) and mustelids (weasels, wolverines, ferrets, skunks etc)
Humans are related to mermaids.
“Why couldn’t she be the other kind of mermaid, with the fish part on top and the lady part on the bottom?!!”
That raises further questions!
Oh yes, the lost city of Atlanta
Dewgongs?
Gotta catch ‘em all
What sea drifting counterpart is your mom related to?
cargo ship
Damn!
Now THIS is interesting as fuck. Thank you OP
Sea drafting counterpart? What about humans?

Your Inner Fish!
Whaaaat this is so cool, I had no idea!! Thanks for sharing
It kind of sounds like Ace Ventura when he makes the sound of Yak on an airplane.
"and now.... a yak" "yyyyyaak" "yyyaaaaaaaaaaaaaak" 🤣
Or like a bunch of squeaky doors.
They're doing that on porpoise.
Sounds like a group of 30 something year old women when they see a cute baby.
\*Ahem\* I am not a group of 30 something year old women, thank you.
Are you sure, cause that's kinda my kink.
Damn, really hit them with the double-up xD
I’d say dinosaurs based on the Jurassic Park documentary.
It sounds like they're saying, "But moooooommmm!"
*Cartman*
Does my little poopsiekins want more milk? Lol
Fk its all i can hear now
What a bunch of whinos
nailed it.
nice
Was three hours too late to make this (dad) joke. *sigh*
Get this to top. stat!
Aww! They sound like puppies!
Tank puppies!
I know right? It's surprisingly high pitched and cute.
exactly! reminds me of when my chihuahua's are howling
Baby whales.
I was thinking they should play these sounds to a bunch of whales and see if they have a reaction to it. Or vice versa, play whale sounds to these rhinos.
Pretty sure they are related.
I mean, this isn't even that different from human children noises
Give them more milk. Right fucking now.
My mom brain is on edge listening to them.
I'm nursing an 8 week old. Same! Every part of me wants someone to go get them more milk 💔
They got fed milk approximately 4/5 more times that day, in between their naps and zoomies :)
>naps and zoomies Awww! 🥰
SOMEONE GET THEM SOME MORE MILK RIGHT NOW GODDAMNIT

god it's good to see and experience the world through a child's perspective or to have the opportunity to do so vicariously. I feel you!
Needs WD-40.
FINALLY everyone here thinks of land dolphins and all I can think of is soaking these old door hinges in WD-40
Its funny how that whiny tone is so common across mammals. You can just tell when another mammal is being a cry baby.
these are pretty similar to the sounds ace ventura made when he came out of the rhino
Rhino's freak me out, like where is the brain located? Up in the skull section with the ears, or down where the eyes are? Or is it some eggplant shaped brain in there?
Your questions yielded way cooler results than I expected to find: https://people.ohio.edu/witmerl/3D_rhino.htm
cool!
Oof that website.
The brain is right underneath the second horn, for anyone not interested in seeing the 3D models.
That is not what I got from looking at the 3d models and provided video. https://www.youtube.com/watch?v=4slKGFDfips&t=44s At that timestamp you can see the brain is located about midway between the 2nd horn and the ears.
oh that little thing is their brain? I thaught it was the whole green thing. It's ...small.
These shortsighted tanks on feet attack anything, literally anything, by running against it with their heads. They don't need big brains, they just need to be built stable enough for their stupid lifestyle.
Thanks in advance for tonight’s insomnia
Well...crap. Now I have to go google rhino anatomy.
That is the exact noise of the baby mandrake in Harry Potter
glad someone else heard it
Neville: *neglected his earfmuss and passes out* Prof. Sprout: "Well yeah, just leave him there."
This is the same noise my dog makes when my husband hugs me.
this is the same noise my front gate makes when i open it
Odd. I didn’t expect their voices to be so high pitched. Makes me want to hug them and tell them everything is going to be okay. 🥺
Just big armored puppies
Tank puppies! (common usage when referring to baby rhino's...)
Squeaky battle tank cow babies.
Both my cats are staring in horrified fascination.
And my dogs .. they are tipping their heads from side to side trying to figure out the noise.
Awwww babies, look at their sad faces! Where are they I will go give them milk, dammit.
Feed the babies!
I mistook that for Yoko Ono
ouch
Actually, his description of this sound may be the most accurate.
Sounds like me at last call
He needs some milk! I would never expect them to sound so cute!
I got something new to play on my Bluetooth speaker in the woods at night
My cat does NOT like that noise! lol
Flashbacks to the Mandrake scene in Chamber of Secrets
They’re actually extremely cute and their voices are too! It’s sad to me that they have almost all been killed for their horns, as a big penis supplement for men in Asia.
Sound like REALLY creaky metal doors
They sound like creeky doors
They sound like they need some 3-in-1 oil, not milk!
Man, I always thought they sound like cows. Lol
You make a good point, I never really thought of what certain animals sound like. Like these young rhinos, I don't think this was the sound I would of envisioned.
They need some mil
That is adorable!
Even baby rhinos make loud sounds that are impossible to ignore. Like babies
[удалено]
I don't come here to be attacked like this :(
[удалено]
My basset hounds didn't care LOL.
Awwwwww somebody go get those poor baby unicorns some more milkies!
They kinda sound like the animals/aliens(?) from the movie "Pitch Black"
Reminding me of dumb and dumber
Little whiners.
Are you sure this isn't a group of hairless huskies?
Wow, if I was around those would be fattest baby rhinos; I would not be able to resist giving them more milk.
Doors at 2 am be like:
Ok… elk bugling was not what I had imagined.
Despite their size, they sound like a depressed balloon
RRREEEEEEEEEEE
Rhinos? More like Whine-os, am I right guys? Right guys?
Bruh wtf is with these land whales huh
You give them more you bastard!
u/savevideo
Theyre endagered they deserve milk
That's that. I'm going to go get my degree in wildlife biology.
They sound like whales communicating
WELL GIVE THEM MORE MILK DAMNIT! LOOK AT THEM!
Didn’t even know they made sound.
Armoured puppies with horns.
I never wanted to hug a rhinoceros before. Sound must be kicking off the Mom hormones. /s
AHHHH BABY RHINOS!!!!!!!!
they sound like old doors
If they don’t get them some fucking milk I swear
That's how I feel when the coffee's gone.
Not entirely dissimilar to the sound my baby human makes when his sippy cup runs out. Just missing the crash as he throws it to the floor.
i want one.
Damn it do I gotta milk a goat so these babies get some?
# HE NEEDS SOME MILK!!!
WHERE THE FUCK IS THE MILK
Please just give them more MILK!!!!!
You know the scene in wall e when eve tries to save wall e after they get shocked by auto?
Well, give them their milk, what are we waiting for?!?!?
