How We Domesticated Cats (Twice)

How We Domesticated Cats (Twice)

When a group of French archaeologists landed
on the island of Cyprus in 2001, they quickly found that they were … outnumbered. Despite having a population of about 1.2 million
people, Cyprus turned out to have an even bigger population of cats. By some estimates, as many as 1.5 million
felines, including both pets and feral cats, roam the country. You can find them practically everywhere! But Cyprus is an island in the Mediterranean,
and, if you’ve ever tried to give a cat a bath, you know most of them aren’t big
fans of water. The closest mainland is Turkey, about 70 kilometers
away! So how did all of those cats get there? Well, those French archaeologists might have
found the answer. While excavating the site of an ancient settlement,
they discovered something quite surprising. It was the grave of a man who was buried alongside
offerings of flint tools, seashells and … an 8 month old cat. Dating to around 9,500 years ago, this burial
represented some of the oldest known evidence of human/cat companionships anywhere in the
world – predating the more well-known love of cats in ancient Egypt by 4,000 years! But when did this close relationship between
humans and cats start? Who were the ancestors of domesticated cats? And how did humans help cats take over Cyprus…and
eventually the world? For that, we can thank the complex process
known as domestication. And yes — even though we let them poop in
our houses and knock stuff off our counters and sometimes pee in the laundry basket for
some reason — we did domesticate them, even though it might not always feel like it. Today’s domesticated cat is its own species,
known as Felis catus. And we can trace its origins to a species
of wild cats called Felis silvestris, which is made up of five different subspecies. Based on studies of the genomes of modern
house cats, one subspecies, called Felis silvestris lybica, is the direct ancestor of all domesticated
cats today. And those wild cats — often referred to as
African wildcats — can still be found across North Africa and Southwest Asia. And as you can tell, these ancestral cats
don’t look very different from their domesticated descendants. They’re slightly larger, and they don’t
have the color variations in their coats that we see in house cats. Instead, they mostly have what are called
mackerel-tabby patterns, with stripes that run perpendicular to their spines. You can even find this same pattern in the
cats depicted in ancient Egyptian artwork. Now, these wild kitties are solitary creatures
that don’t have the same social structure that other animals, like wolves,
do. So scientists think that the domestication
of cats was probably a different process from the domestication of other animals. But unfortunately, the fossil record of African
wildcats isn’t great. Most haven’t been preserved well enough
to be used in genetic analysis, which is partly why it’s been so hard to figure out how
cat domestication actually worked. Some of the oldest known fossils include specimens
from Cyprus that are about 11,000 years old, and others in Turkey from around 10,000 years
ago. So, how did we get from Felis silvestris lybica
to Felis catus? Well, you know how hard it is to get cats
to do stuff. It took a lot of time! And we still don’t know the full picture,
but the first step is understanding the different ways in which animals can be domesticated. A species is considered to be “domesticated”
when it becomes genetically and permanently modified through human-influenced breeding. And it has to be reliant on humans on some
level, like for food and shelter. Or to clean out the litter box. And American archaeologist Dr. Melinda Zeder
has proposed that there are three pathways to domestication: the prey pathway, the directed
pathway, and the commensal pathway. In the prey pathway, wild animals are first
hunted by people. Then, in order to better control the hunts,
people begin to manage herds of the animals, like goats and cattle. This leads to captive breeding and eventually
domestication of the species. With the directed pathway, people use lessons
they learned from previous attempts at domestication, often through the prey pathway. Horses and beasts of burden, like donkeys
and camels, were most likely domesticated this way. We fast-tracked their domestication in order
to harness their abilities to walk long distances and carry heavy loads. And finally, in the commensal pathway, wild
animals are attracted to human settlements by food. They go where the people go, feeding off of
their scraps, or on prey that may have also been drawn to the humans, like mice or rats. And this eventually leads to domestication. This is probably how cats were domesticated. For thousands of years, they stayed close
to human dwellings for food, but weren’t necessarily close to the people themselves. But eventually, people noticed that cats were
actually pretty good at catching the pests that plagued their food stores, and began
to actively entice them to live in their settlements. And we can get glimpses into this process
by studying the remains of ancient kitties. For example, isotopic analysis of cat remains
from 5,600 years ago in northwestern China has revealed trace amounts of millet, a staple
grain in the diet of the human villagers there. This suggests that cats were eating the mice
that were feeding on stored millet, no doubt a useful service for the villagers! And the isotopic data from one cat revealed
a diet that had less meat and more millet than expected, suggesting that it either scavenged
from, or was fed by, the villagers…. Aww! So what did domestication, as a process, do
to change wild cats into house cats? Well, physically, domestication has made house
cats smaller than their ancestors, and resulted in new varieties in coat color and patterning. These included new variations of the tabby
coat, and the introduction of black, orange, and white colors. Most of these coat changes are fairly recent,
and came about as recessive genes in wildcats became more prominent. Then by the 19th century, scientists believe,
people started to selectively breed for more variation in markings and colors. But beyond size and color, domestication really
didn’t change the morphology of cats that much compared to, say, dogs, which have seen
major changes to their whole bodies. This is mostly because of differences in breeding
practices, as different dog breeds were bred for specific purposes. Modern cats also maintain more genetic and
behavioral similarities with their wild ancestors than most other domesticated animals do, including
behaviors related to eating and breeding. This is probably because of interbreeding
between domesticated cats and surrounding wildcat populations. But the thing is, wildcats are actually thought
to have been domesticated twice – once in southwest Asia about 10,000 years ago, and
again in Egypt, about 3,500 years ago! This is based on an analysis of the genome
of modern cats, which suggests that two different source populations contributed to the current
gene pool at two different times. And we’ve also found archaeological evidence
that supports multiple points of domestication. For example, in Egypt, six burials have been
uncovered at the site of Hierakonpolis containing two adult cats and four kittens. And they date to between 3,600 and 3,800 years
ago. Their smaller bones closely match the size
of those in domesticated cats, and one cat’s skeleton even showed healed fractures, suggesting
that it was cared for by its human companions. After about 3,000 years ago in Egypt, we can
see these relationships becoming closer, through art and iconography that show cats alongside
people. And from there, it looks like cats were brought
to Rome by early Greek settlers, as well as through interactions between Rome and Egypt. As civilizations begin to expand around 2,000
years ago, especially within the Roman Empire, cats followed as well. We know ancient Romans kept felines as pets,
based on various artworks,like mosaics, that show cats in more domestic settings, often
hunting prey. Roman cats were most likely adopted into households
to catch rodents and other pests – much like they did in the early stages of domestication. But none of this actually tells us where the
story of cat domestication started: after all If the oldest evidence of domestic cats is on the
island of Cyprus, then who brought cats to Cyprus in the first place? Well, all we know is that, at some point during
the Early Holocene Epoch, possibly 11,000 years ago, people from southwest Asia began
to migrate to Europe — including Cyprus. And they brought with them that subspecies
of cat that was the ancestor of our domesticated cats. And, cats being cats, we ended up with millions
of the little guys In modern day Cyprus, the cat population has
boomed to the point of being considered an infestation. Cats are often seen as vermin, and there have
been many attempts to get a handle on their growing population. Luckily for the feral cats, though, there
are many sanctuaries run by volunteers who try to care for every stray. But it’s not just on this island where cats
have commanded such a presence. Our relationship has been mutually beneficial
enough that domestic cats have truly taken over the world. Today their estimated overall
population of 600 million. Cats have achieved world domination, but if
it wasn’t for us, they might’ve never have left Africa and Asia. We carried them to places they otherwise might
never have seen. So maybe our pet cats should treat us with
a little more respect. Mine could’ve started by not peeing on my
laundry. But I loved him anyway. Big thanks and kitty snuggles to this month’s

  1. By latching onto humans — cats have put themselves at the top of the food chain. They went from eating mice to cows.

  2. I always feel like all cats remember when we the Egyptians used to honor them as Gods… ….. ….. ..and they never let the rest of us forget.

  3. Wow. I didn't realize cat people were so clever and funny. These are some of the most intelligently amusing YouTube comments I've ever seen. And notice the spelling and grammar. It's almost all correct! That might be even more astonishing.
    (Oh, wait a minute. That's right. I'm watching "Eons," not Russian dash cam videos. That explains it.)

  4. "Cats were domesticated in multiple places at multiple times" so basically the whole world looked at these creatures and some point or another and said "cat good."

  5. 7:30 Clean their litter box more often, and get at least one more than you have right now (a plus one rule is standard. If you have one cat, get two boxes. Three cats, four boxes… and so on). Also try installing a few places up off the ground they can perch on in social area. If your cat is peeing on your laundry, there's a reason behind it. These are three most common reasons I find it happens.

    Also, if your cat is peeing in your clothing, that smell tends to stick. Add a generous amount of baking soda to the wash. You're welcome.

  6. See Scientifically proven that cats rule the world!!!!! and you thought cats vs dogs was just a movie stupid human HAHAHAHAHAHAHAHA

  7. African Wildcats have now been promoted to it's own species status- Felis Lybica. Eontologists should've picked that up considering it's a recent video.

  8. No no no no… here is my theory: maybe Cypriots were greedy for cats this is why there were so many on the island, and the cat buried with the guy served as food for the symbolic journey to paradise.

    I'm kidding of course, it's the opposite, Cypriot cats were greedy for humans, this is why there were so many humans on the island.

  9. Cats in a city need us. In the other hand, a cat in the suburbs or forest don't need us as they can hunt easily in a suburb than in a city.

  10. I had, u unwittiny, bought a house with a bit of a rodent problem. I was considering calling a pest control company. Within a few days, I began to notice mice in my basement that had been violently slaughtered. My 17 year old cat with no front claws had immediately gone to work eliminating them. She got all but one; that one I got with a trap. She got out one day and was hit by a car😩. She was a sweetie and I miss her.💔

  11. Cyprus and egypt are too close geographically to ignore the relation in the cultures between them and the people found on cyprus.

  12. You cease whatever you are doing, you come and bow before me, you dedicate your life to my service. You just stop and leave it all behind for me. The more that I embarrass myself in the mean time, the more you lose.

  13. The feeling of "cats domesticated humans" is why we probably love them so much. With dogs, we took to them (and look how grateful they are for it – this is why we love them). Whereas cats took to us, and we're grateful for it!

  14. Looking at my cat: "This man here says you should treat me with more respect considering what I and my ancestors have done for your world dominance!"
    My cat: "Bugger off, let me sleep and feed me."

  15. You now need to do the origins of dogs!!!! Please ! Is the current consensus that dogs are a sister taxa to the grey wolf??

  16. "so domestication of these cats would have been different than wolves…"

    Yeah? Did you find one unafraid cat of humans and you feed it until it starts hanging out with you and your other fellow humans yeah?

  17. Quick tip, if your cat pees on your laundry he/she prob doesnt like the litter you are using or the litterbox isnt cleaned out often enough 😉

  18. We need to start decorating dead otters and putting them in our graves. Once the radiation starts to subside in 4242 and the archaeologists return to these lands it'll really cook their noodle.

  19. 600 million doesn't seem like a lot; considering there are over 7 billion of us. I guess i have 31 peoples' worth of cats in my house. I can't tell them that, tho; as it would inflate their egos further.

  20. The title is incorrect. It's suppose to be how cat domesticated and made humans their slaves (except for some Asian countries)

  21. Really informative video. I'd still have to say that there is something about their behavior that would indicate they are simply tame and not fully domesticated. Or maybe some percentage of their gene pool leans towards being less domesticated.
    Either way; they're funny little independent house predators 🙂

  22. Canines actually have an attribute in their DNA that makes it more malleable.

    Cats don't have this and can't be easily bred into the weird freaks of nature dogs come in.

  23. I'm sorry cats aren't domesticated a cat will stay with you if it wants to if not it will simply leave and find a better human. We don't own cats, we love them and we feed them and pet them and clean up after them but a cat only stays with you if it wants to. Cats choose us not the other way around.
