gold fish can actually grow to significant sizes, most of them just have stunted growth due to aquarium conditions- it's why you can see them get bigger in ponds, or better quality setups
Got a house with a pool I asked how do I retrofit the system for fish. 2k later rainbow trout goldfish bigger the 2 feet and carp. Hold up a 2 foot gold fish yes. In a great lake they invaded there up to 3 feet and up to 40 pounds.
We had a largish pond in our backyard one time, and my dad decided to release some goldfish in it. Just standard little cheap goldfish. They vanished almost immediately, and we assumed that they had been eaten by something, but a couple of years later all of a sudden there were several dozen goldfish showing up, but they weren’t just plain gold, there were black and red and calico and pinto - pretty much any color you might see on a carp. Then a kingfisher discovered them (exquisite little bird!) and within a few days the only ones left were those who were black or had black backs. Natural selection in action.
Yep! It’s also why most sources actually recommend housing them in tanks that are a minimum of 29 gallons or larger, and more if you have more than one. Those little goldfish bowls most pet stores sell are actually terrible for them.
It's interesting that humans have had the same ideas a few times. Like dogs were domesticated a couple times and cows as well. Like someone in one area is like "yeah im gonna be friends with this animal/use it for a purpose" and then someone on the other sode of the world thought the same thing eventually and did it again
How many kids have fed squirrels? Most. Trying to build connections to animals in our surroundings, no matter the type, is part of our instincts apparently. And some animals are just more useful and/or easier to interact with in some way, resulting in large scale keeping of such animals. By people unrelated to each other, at that.
This is one of the subjects that fasinates me. I've read cats return to a feral state after five generations of being in the wild. You might want to have a video on the silver fox project and reptiles being domesticated,mainly leopard geckos,ball pythons,house snakes,corn snakes,bearded dragons,crested geckos and gargoyle geckos.
Cats are about roughly 20% domesticated. If they aren't handled as kittens, they can become pretty feral, and it is hard to make them housepets after 8 weeks old. They are pretty unique as far as domesticated animals go, but we all know that already. This is despite the fact that they have been tamed longer than people think. In 2021, the burial of a tamed cat was found on Cyprus. So, we have been evolving with our fuzzy friends since at least 7,500 years ago. There have been some biological changes, but not much compared to fully domesticated animals. You should read up on that archeology paper, it is interesting.
How is this channel just funded by youtube? Serious question. Ive watched a dozen videos now and i dont think ive seen one ad. Or patreon. Or join. Or thanks button. Youre the man, wanted to thank you ❤️
Oh, and hornless cows are often that way because their horn buds where removed when they were little not because we have managed to breed out horns... same for goats actually
I think that's what he meant to say; poaching caused an extreme evolutionary pressure against large tusks. Since the terrestrial superpredator isn't as interested in specimens with small or no tusks they are more likely to survive and reproduce.
Highlands Cows are great pets. They are sweet and cute and their fur is soft and fluffy. Meat is a waste of ressources, you can live perfectly healthy on a plant based diet. Millions of people have been eaten plant based their whole life and are in average wayyyyy healthier than Omnies
@@CordeliaWagner1999meat is the reason humanity got to where it is. All meat eating animals are significantly more intelligent. But go ahead, stunt growth because you can't accept the cruelty of nature
@@CordeliaWagner1999 Meat can actually be a more efficient utilization of resources. Highland Cattle for example are able to traverse mountainous terrain unfit for farming and eat all sorts of vegetation that humans are incapable of digesting. They regenerate soil systems and keep plants from overgrowing and convert that energy into highly nutrient dense protein that we can then consume. Bison were a very important part in both the environment and diet of some native cultures.
The elephants tusk correlates with the survivors because those with little to no tusks were left alone and the ones were killed by poachers meant that all of those who survived and mated gives birth to elephants with little to no tusks
Hmm. Interesting question. Looking at history, artificial selection has been attempted quite a few times, and continues to this day. Today's distributions of various types of humans with relatively small differences are witness to that.
@@shizlittlebam Then stop eating salmons in general (both farm and wild), and other farmed animals or plants or fishes or shrimps or fruits, not just farmed salmons. Stop eating in general is the best for environment. About health, I am not sure the air is clean enough to inhale.
@@4rg3s The difference in agricultural farming and salmon farming is that harmful effects to the environment can be mitigated or eliminated with agriculture while many cannot with salmon due to the nature of farming fish.
@@soulfourger Human farming activities of any kinds have been bad for the natural environment since the pre-history, well since our kind learned to farm. Cutting/Burning down forests for fertile land. Altering river deltas for human habitation. Domesticating wild animals. So on and on. Pick your poison. Starvation, animal extinction or farming.
Fish grow to the limits of their environment. If you keep them I an aquarium, they won't get very big. You take those same fish out to a pond, they'll grow larger.
Didnt arochs exist during ancient egyptians era, egyptians did drew enough arochs. But still i think arochs and cows now have common ancestors not aroch being cows ancestors
Do people realizse the exact same thing hapened to humans in general you al know the ancient humans were so strong and performant now we strugle to walk
Quite the opposite: it absolutely confirms evolution. It's exactly this ability to for a specie's gene pool to adapt and change (or be changed and adapted by selective breeding) that drives evolution.
For evolution to be true, then the water and oxygen cycles would have to have evolved to support humans. Evolution is a 19th century scientism religion.
The big cow on that thumbnail, I've seen a couple of that breed, and they are genuinely gargantuan compared to other cows. Taller than me at the shoulder, and while I'm not especially tall, most cows still don't tower over me. But that breed does. I can't even guess how much they must weigh.
~~Forgot what some might consider a major aspect between Farmed Salmon&Wild? Initially prepared, Farmed goes through one last process altogether Wild don't before finally being available to the public. Those who don't know likely figure what it is after this? Their diets, of course, being vastly different&having various effects as it does. The entire segment visually showing the differences still intact never showed/saw it w/the filets once? And you won't either. Even someone whose never eaten salmon could picture it in their mind what it looks like? Reddish pink meat. Farmed filleted 5min after being pulled from the lake resembles a hardening pile mud or shit still little wet&partial grain pressed into it.
Yeah goldfish grow to the environment that they are living in I've seen some huge goldfish bigger than koi fish my neighbor had a huge koi fish pond and he put baby goldfish in there and they became way bigger than the koi 😅 ive seen some goldfish in a small man-made pond that get enormous
Normal, comet, shubunkin and other non-fancy goldfish should be kept in either a large tank or a pond, latter is likely when they’re older tbh. They get BIG. Also don’t buy celestial eye or bubble eye goldfish, if you couldn’t tell from looking at them, it’s cruel asf to breed those poor things. Some other breeds are also questionable but they’re the worst.
I think it's more of the fact that the elephants with the long tusk gene were kill off , because he said 90% was targeted for their tusks. So that would leave only or mostly the ones with literally Little to No tusks as the one now breeding. So the long tusks gene is or was basically killed off .
The bulls and boars are really interesting bc we have accounts of when the animals were first being domesticated and when even the wild ones hadn’t grown small. Take the Greeks for example; we have many myths and historical accounts of hunts where massive wild boars were killed. Most notably the Caledonian boar. This myth didn’t come out of nowhere after all. Anyways domestication is always an interesting topic and even if unintentionally humans have effected the evolution of animals so greatly that even wild animals have been affected by people
Tusks are a hereditary trait. So it goes like this: elephants with big tusks were killed, leaving elephants with small or no tusks to be the only ones left to reproduce with each other. Then elephants with tusks at all were killed, leaving only elephants with no tusks to reproduce.
Only the fancy ones. The common ones are basically just orange carp. They still need several orders of magnitude more space than most people think, though.
I really appreciate these videos but asking for a thumbs up at the beginning of a video before watching the content it's just 10,000% annoying. Why would I like a video before watching it?
Damn... I know the pufferfish is gonna get eaten but do they have to use wire cutters to cut their beak (teeth) off while the fish are still alive? Cant yall wait until yall are gonna cook em? I mean since they don't have to catch their food on the bottom and like crush up shells and s*** i suppose they wouldnt need the beak. And it's possible that they attack each other and thats why they need to be removed but damn wonder how they would feel if somebody just came and cut/pulled their teeth out with pliers.
Ain no one gonna talk about that cow on 4:16 that cow got muscles on his muscles what the hell they been feeding that white cow making his ass so muscular I swear like you can see muscles on that muscle that cow look like he can beat my ass and your ass that's no cow that's a thug
An interesting subject and well scripted, but this fellow's voice is very grating - to the point of irritation - so much so that it discourages me from watching any others he may narrate.
I like videos at the end because you have to make a good video for me to like reminding me ok but stop at the beginning of the video just a waste of time
