## Summary

This video provides a comprehensive tour of the canine family, from extinct ancestors like the dire wolf to modern domestic breeds. It covers the evolutionary relationships, unique adaptations, and diversity of wild and domesticated dogs.

### Key Points

- **Introduction to Dog Diversity** [00:03] — Domestic dogs descended from wild ancestors that cozied up to humans 15,000-30,000 years ago. Today, an estimated 1 billion dogs live worldwide.
- **Extinct Canines** [00:45] — Epicion was the largest dog ever, size of a grizzly bear. Dire wolves were apex predators in ancient America. Leptoion, the 'dog father,' gave rise to all modern canines.
- **Foxes: The Least Related** [01:27] — Gray foxes split off earliest; island foxes evolved dwarfism due to limited food. Red foxes are widespread; a Soviet experiment tamed silver foxes. Arctic foxes change coat color; fennec foxes have large ears for heat dissipation.
- **South American Canines** [03:28] — Crab-eating foxes, bush dogs (pack hunters), maned wolves (long legs for grasslands), and short-eared dogs (secrete anal gland scent) are unique to South America.
- **Jackals, Painted Dogs, and Coyotes** [04:23] — Black-backed jackals have broad diets; African painted dogs endangered; dholes exhibit reticulate evolution; coyotes expanded range due to adaptability.
- **Grey Wolves and Domestication** [05:06] — Grey wolves are pack hunters; domestication led to modern dogs. The Bon-Oberkassel dog (14,000 years ago) was likely a pet. Dingoes arrived in Australia via boat.
- **Notable Dog Breeds** [05:52] — Basenjis yodel, Xolos (Mexican hairless) guided souls, Mastiffs weigh over 100kg, Huskies run ultramarathons, Poodles were circus performers, Labs are popular pets, Golden Retrievers from Scotland, German Shepherds are police dogs, Belgian Malinois athletic, Whippets fast, Dachshunds hunted badgers, Greyhounds fast, Chihuahuas small, French Bulldogs popular, Akitas loyal (Hachiko), Great Danes tall, St. Bernards rescue dogs.
- **Mixed Breeds and Muts** [08:40] — Labradoodles are hybrids for allergies; pitbulls often in shelters; muts like Laika the space dog are famous.

this. And all of these good boys and girls are too. Wild canines are wildly continent. And ever since the wild ancestors of dogs first cozied up to the fires of ancient hunter gatherers somewhere between 15 and 30,000 years
ago, domestic dogs have reaped the benefits of one of the most successful history of the planet. An estimated 1 billion modern dogs live all over the world, including several who live with the people that made this video. Hi, I'm
David. This is Kubu. And this is Minute Earth. And in this video, I'm going to take you on a tour of the dogormous diversity of the K9 family. Oh yeah, wall. You can order it from our merch shop on dftba.com. I'll talk more about
let's start with a few extinct canines first. This is Epicion, the largest dog that ever existed. It was roughly the size of a grizzly bear. And this is the dire wolf, one of the apex predators of the ancient American West. If you go to
the labrea tarpits in California, you'll see hundreds of direwolf skulls that seems these puffers just couldn't resist going after giant mammals that had And then the dire wolves got stuck, too. And the last extinct canine we'll
discuss is Leptoion, the literal dog father. This little omnivore burst onto the scene more than 30 million years ago in North America. and eventually gave rise to every canine alive today. Now, we're going to pivot to those canines
the ones that are least closely related to domestic dogs and get closer and love as we go. This means the first modern group of canines will be touring is the foxes. As scientists have learned more about how canines are related,
that we call foxes aren't actually that closely related to one another. For example, there are two foxes that are relatively separate from all the other pups in the canine family. The ancestors of gray foxes split off from the rest of
ancient canines before any other species did. Modern gray foxes have long claws allowing them to escape from the coyotes and wolves that live nearby. The island fox is very closely related to the gray fox. A few thousand years ago, a few
islands off of the coast of California. Over the ensuing millennia, their descendants shrank about 25% due to the limited food on the islands and became a new species, the island fox. A prime example of the phenomenon of island
dwarfism. Okay, let's get into the rest of the fox group. The red fox is perhaps the most widely distributed canine in the world. It scampers around a huge range that includes North America, Europe, Asia, Northern Africa, and the
range, their coats appear black or silver. Beginning in 1952, a Soviet some of those silver red foxes to see if he could eventually produce tame how humans had first domesticated wolves. It took a while, but more than
40 generations later, his team has created a small population of tame silver foxes with floppy ears and curly tails who love to snuggle with humans. As winter fades in the far north, the Arctic fox sheds the fluffy white coat
and grows in a thinner coat packed with more melanin, which it then uses to blend in with the summer landscape. The fenic fox is a desert dweller, and pretty much every part of its tiny body is optimized for life there. Of course,
which dissipate heat and help it listen for prey hiding under the North African sand. It's also got shovel-shaped front feet to help it dig quickly to get into though it looks like a Pokemonified version of, well, a raccoon, is probably
pretty closely related to those foxes. It's also the only canine that that's that group. Now, let's head over to another branch of the canine family might be a little less familiar with. Let's start with the crab eatating fox,
which again is not really in the fox group. Crab eating foxes stalk mud named after to wander out into the open. Next, let's meet the bush dog, a squat in the marshes of the Amazon rainforest. Bush dogs can actually take down big
prey like capibaras by hunting in packs and nipping their quarry's heels until there's the maed wolf, which looks like a red fox with cartoonishly long legs. what's going on in the South American grasslands. Finally, there's the
short-eared dog. These elusive South American natives are one of the few from their anal glands. They often live in the abandoned burrows of giant armadillos. Okay, let's turn to the group of canines that are more closely
related to modern dogs. The blackbacked jackal is famous for its broad diet. It will eat pretty much everything from grasshoppers to seals to impalas to the hard melons of the nar tree. The African wild dog uh I mean the painted dog has
conservation groups attempt to prevent its impending extinction by making it sound well less wild. The endangered doss of southern Asia might be the most famous example of a phenomenon called reticulate evolution. That is they might
hybridization between wolves and painted dogs. And here's the infamous coyote. across North America has been bad for most species, it's been a boon for coyotes whose flexible diet, willingness to live near humans, and ability to
allowed them to tremendously expand their range and numbers. And of course, there's the grey wolf. Grey wolves are the ultimate pack hunters. Their what led them to the huts of ancient humans, which eventually led to their
domestication as the canines we love today, modern dogs. One of the first dogs we know was the Bon Obercastle dog from about 14,000 years ago. She survived a terrible disease as a puppy and likely wasn't any use as a hunting
just kept her as a pet for snuggles. those earliest domesticated dogs. It seems as though a group of them traveled by boat from Asia to Australia several thousand years ago. Once they got down
literally, and have since become the apex predator of the outback. Since humans have been selectively breeding dogs for all sorts of traits, resulting can't cover them all here, but let's talk about some that really stand out.
Benis are short-haired African hunting dogs that are famous for the fact that vocalizations sometimes sound like yodals. Zolos are sometimes called Mexican hairless dogs thanks to their origin and appearance. There's evidence
their owners since they were thought to be reliable guides to the underworld. Mastiffs often weigh more than 100 kg and have been used as guard dogs, hunting dogs, and even military dogs. Nowadays, they're more known for their
drool than their ferociousness. Huskys and malamutes are often used as sled they are able to use their energy reserves, they can run ultramarathons for days at a time, making them the best endurance athletes on the planet.
distinctive curly coats, were often used as performers in old tiny circuses. black, or chocolate colored, were originally bred in Canada to be game their friendly temperament and smarts, labs are now super popular pets. And
labs and were bred to do many of the same jobs, they first came from Scotland. Perhaps the most famous golden retriever is Buddy, the star of the Airbud cinematic universe. The German Shepherd is super popular and learns
their work as police dogs and search and rescue dogs. Belgian shepherds, as the Malininoa, are extremely athletic and trainable. Whippbits were the known for their speed and nervous energy. Occasionally, a genetic mutation
that only occurs in this breed, creates super muscular dogs known as bully whippbits. Dachshunds, also known as wiener dogs, were bred to be able to fit into burrows and flush out badgers. In fact, the German word for badger is
docks. Nowadays, though, dachshunds are mostly just cute, long pets. A greyhound can hit speeds of more than 75 km/h. They have the highest percentage of fast switch muscles of any breed. The smallest of all dog breeds, Chihuahua
where they originated. The smallest Chihuahua ever, Pearl, is only 5 in long and weighs just over a pound. To me, French bulldogs look kind of like They are now the most popular dog breed in America, having knocked Labs out of
the top spot in 2022. Akitas are known for their loyalty. Even after his owner died, Hachiko the Aikita waited at the train station every day for 9 years for him to return home from work. In the process, he became a national hero as
the ultimate symbol of faithfulness. Great Danes are the tallest dogs in the world. Standing on his hind legs, the Great Dane Zeus was taller than Shaq. He could drink directly from the kitchen sink. St. Bernards are famous mountain
rescue dogs. Barry the St. Bernard is credited with saving more than 40 people in his work for a Swiss monastery. He'd sniff out people trapped in avalanches, on them to warm them up. Of course,
that aren't considered purebred at all. Some are like labradoodles, hybrid lab as pets for folks with allergies to pet dander, but now are just the cute non-shedding pet of choice for all sorts of folks. And then there's the pitbull,
bunch of different short-haired muscly dog breeds with square heads. Because of fights and often unfair reputation as being aggressive, pitbulls are often in animal shelters in order to make them more adoptable. And finally, there are
muts, which are basically combos of all sorts of breeds, like Kate's dog, Watson. Perhaps the most famous MUT is Leica, who started life as a stray Soviet street dog before being selected by scientists to be part of the Sputnik
program. She was the first animal to orbit the Earth, though she died before she could get back home. That's a lot of dogs. Thanks for joining us on this tour of the incredible diversity of the K9 family. If you liked
