TIMESTAMPS FOR SPIDERS/ARACHNIDS 1:39 -> 1:46 Several, animated (intro) 2:54 -> 3:01 Several, illustrated (excerpt of old species descriptions) 9:47 -> 10:08 Several, animated (dancing paradise spiders) 10:22 -> 10:23 Several, animated (male paradise spiders with big bushy eyebrows) As a spider scientist (and the science consultant for CCZoo), I love these wonderful animals, but I realize that being startled by a spider can be scary (even if you like them!). An important part of overcoming arachnophobia is building positive interactions with arachnids on /your/ terms, so hopefully this helps some of y'all do so and enjoy the videos.
As someone who is both fascinated with and knowledge about biology as well as an avid Pokémon fan, the Thought Bubble section was filled with much-appreciated Easter eggs. (Honestly, I've been trying to figure out what egg groups mean for realistic Pokémon biology for years now!)
In pokémon biology, the evolution family more accurately classifies the species (while individual "species" are more akin to the life stages) rather than the egg group. If you really stretch it out, egg groups are somewhat like phyla (if a species could belong into two phyla, which is impossible IRL)
One of my favorite things about grad school was learning that so many other scientists (esp those that study arthropods) are huge Pokemon nerds! While far from a perfect analogy for real biology, the idea of traveling the world and discovering new fascinating animals is what inspires many taxonomosts! (Also, yeah I've thought about that egg group question too. The best hypothesis I've had is that most of the genetic info (basically everything that makes a Pokemon the species that it is) is passed down maternally, through the DNA in the female gamete, and does not combine with paternal genetic info from the male gamete. But since males can contribute some traits to offspring, there must be a way for their genetic info to be passed down. I'd guess that things like IVs and egg moves are carried on a separate system of genetic info (like how bacteria have their main chromosome(s) and a separate plasmid) that *does* combine with that of the mom's. Finally, it seems that females are unable to induce reproduction without mating, but don't actually require genetic material from another individual to create the embryo (as seen via Ditto) which is similar to how some amphibian females still mate with males, but don't actually incorporate DNA from the males sperm into the embryo (en.m.wikipedia.org/wiki/Gynogenesis))
I'm impressed. Thought Cafe did their Pokemon homework. Stufful can learn Baby-Doll Eyes and Flail, and can breed with Ponyta ("horses"), Wailmer ("whales"), and Mareep ("sheep").
It's very cool to see how the question of "what is a species?" so closely maps onto "what is a language?". It feels like all the main elements are there. Common ancestry, gradual changes over a geographic area, mixing of traits, and so on. The biggest difference i guess, is that languages can "interbreed" even if they're very distantly or not at all related.
Love the pokemon reference. So many children became zoologists or biologist due to pokemon. Me included. And now, many children will become zoologist because Rae and CC Zoology. Thank you. Love you guys.
It was like the sweetest mother gently and patiently explaining a very complex topic to her kids. Love it! I must learn how to teach like that. Thanks for sharing
Sad there's only one more episode, such an interesting series. They should have her do more series or voice overs. Rae has such a great voice - I'd listen to her read a User Agreement.
I was so convinced in the first definition, the one about making non sterile offspring. Now all I knew about the subject turned out to be a lie. Good to know. PS: That thing is clearly related to a red panda.
The genetic species concept is still a useful definition most of the time! The part of what you may have learned that is a "lie" is that this is THE one and only "correct" definition of species.
And sometimes, totally unrelated species look very similar due to mimicry or convergent evolution. For example, a whale looks more like a fish than an elephant, and stick insects are not even closely related to woody plants.
Species make my brain hurt. The fact that there is no real line and that they are essentially undefined and only exist in order to simplify the world is so frustrating to me, but it’s also really fascinating as well.
Nature has no borders, only the human mind creates borders, in nature everything is interconnected, which is why it is as difficult to separate animals into "boxes", as the idea of species. Despite this, the human mind needs the "boxes" to understand the world, so the way is to do the best possible.
There's such a thing as realists about the Species Category. See Richard Boyd (1991, 1999) introduced the Homeostatic Property Cluster (HPC) theory as an alternative view that can accommodate the idea that species are natural kinds
I've always found it strange that dog breeds can be so physically different but are still the same species, when horses and donkeys for example aren't. Or sauropods that seem the same but slightly different sizes!
When I was in high school, the "viable offspring" 'definition' was the one that was used - with no acknowledgement of any nuance or shortcomings. Some of that's on how things are taught (overly, even inaccurately, simplified until you need to relearn it with more specifics to move forward), some of that is time. I was in high school in the 90's. Domains weren't a thing being taught and used yet. When I went back to school as an undergrad in 2008, there was a new top of the tree as well as more - and more open - discussion of the nuance and limitations. I hope that's moving downward into secondary and primary schools, too.
This is literally my dream, especially if I discover something as cute as an Ursus stuffulus...even if that ultimately proves to be physically impossible. I'm so excited; I need a way I can help from home!
Someone has to have already done this, in the event they haven't: 🎶I want to be the very best like no one ever was, to catch them is my real test to train them is my cause. I will travel across the land searching far and wide each pokemon to understand the power that's inside....🎶
I usually do something similar! I try to find a real life animal that the Pokemon is based on/looks like, and I use the scientific name of that animal as the nickname for the Pokemon. It's a lot of fun!
If pokemon were real, trying to figure out how they work would be a nightmare. I would love to explain how a slime monster can interbreed with a humanoid in a dress. At least you would never be bored in biology again.
Uhmmmm guys at @Crash Course are you tackling at Zoology THE FOSSILS 'cause i want to ready for my next grade..... ? Cause this is all about animals, right? 🤔🤔🤔🤔🤔🤔
So penguins emus eagles and ducks are the same species. We need to find the missing link for every thing on earth. This is what passes for science. And it can't be proved
Can you call it a definition if it doesn't accurately give the correct meaning? We aren't discussing a homophone, this is supposed to be a scientific word. So, just be truthful and say that species doesn't have a clear definition. The many definitions referred to are just, whatever that scientific group found convenient.

"Realistic Pokemon biology" is almost always a contradiction in terms.

Got a glimpse of a pokemon and I just slid in
Only reason I showed up
No pokemon theme song? This isn't instagram you can't slide into anything.
I'm impressed. Thought Cafe did their Pokemon homework. Stufful can learn Baby-Doll Eyes and Flail, and can breed with Ponyta ("horses"), Wailmer ("whales"), and Mareep ("sheep").
Ngl pokemon make a great allegory for biology and taxonomy
Yep! I think it's part of why so many zoologists in my generation are big Pokemon nerds
It's very cool to see how the question of "what is a species?" so closely maps onto "what is a language?". It feels like all the main elements are there. Common ancestry, gradual changes over a geographic area, mixing of traits, and so on.

She's amazing! Best most comprehensive explanatory presentation I've seen!
What when your Ursus Stuffulus turns into Ursus Bewearus? 😬
I am loving this series, the host is just lovely and the content super interesting.
Next and final episode...??? Say it ain't so... i love this series! 😭
Love the pokemon reference. So many children became zoologists or biologist due to pokemon. Me included. And now, many children will become zoologist because Rae and CC Zoology. Thank you. Love you guys.
Ay, that’s Stufful from Pokémon! :D
Next and final episode? Already? I'll miss you.😞
It was like the sweetest mother gently and patiently explaining a very complex topic to her kids.
Love it! I must learn how to teach like that.
Thanks for sharing

TH-cam! why did it take 13 episodes for you to notify me this crash course existed?
well at least I get to binge it now...
I took this course from the start. This already gave me a lot of understanding about zoology
Discovering a new species had been a goal of mine since childhood.
I am a very young American generation Z baby and when I saw the Pokémon visuals, I viewed this educational video immediately. ♥️
I'm not ready for the last episode noooo ;w;
Best thought bubble ever in a Crash Course video!
I was so convinced in the first definition, the one about making non sterile offspring.
Now all I knew about the subject turned out to be a lie.
Good to know.

Im a simple man, i see pokemon reference, i like
And sometimes, totally unrelated species look very similar due to mimicry or convergent evolution. For example, a whale looks more like a fish than an elephant, and stick insects are not even closely related to woody plants.
I've been questioning the definition of species this past week and lucky enough, this video came up.
last episode??? ughh this is one of the best thing that ever happened to me

never been this early to crash a course
simply fantabulous
I've always found it strange that dog breeds can be so physically different but are still the same species, when horses and donkeys for example aren't. Or sauropods that seem the same but slightly different sizes!
i always wondered all the questions..this video answers too..too greatful to find this
sNUFFUL? u here? guys i'm telling you he was right here..here in my pokeball.wait...
Zorses and zonkeys exist. Im so happy.
thx for the information
I'm a simple human. I see Stufful, I click.
i'm a simple spider, I see 8 legs, I bang
The Ursus Stuffulus says "ursus stuffulus"
I really want a taxonomic sandwich with a 7 million years filling right now

Pleeeeeeeease let it last longer.... for several more episodes it's not enough.....😭😭😭😭😭😭
Big fan 💯🔥🔥
This is literally my dream, especially if I discover something as cute as an Ursus stuffulus...even if that ultimately proves to be physically impossible. I'm so excited; I need a way I can help from home!
Be sure to watch ep14 as we will be talking about ways you can get involved in Zoology!
More pokemon memes lets go
thanks.
Ligers are the coolest species. Bred for their abilities in magic.
I love this video so much
Amazing!!!
Pokemon crossbreeding efforts building veterinarians and animal lovers in all science feilds.
Bizarre beasts sent me :)
Never thought id see pokemon in a crash course episode but ill take it
I just clicked because of Stufful 😅
I’m a simple man. I see Stufful, I click.
Every spider species exist
Paradise spider: 😏
Do the ring species of the gulls described flow in reverse as well?
Edit: just realised I answered my own question.The process goes both ways.
6:40 I see what you did there...
Having learned from this video that female ligers are fertile, I did some research and found pictures of "liligers" and "tiligers." Wild.
Someone has to have already done this, in the event they haven't:
🎶I want to be the very best like no one ever was, to catch them is my real test to train them is my cause. I will travel across the land searching far and wide each pokemon to understand the power that's inside....🎶
[What's this...? Your Pokemon is evolving!]
Researcher trying to classify the species of Pokemon:
"FREAKING...ヽ(ﾟДﾟ)ノ ...WHAT NOW!?"
Lol I totally named my Pokemon scientific names.
Panpaloavis were two dilophidata of mine that I made up. Let's see if anyone can guess those Pokemon.
I usually do something similar! I try to find a real life animal that the Pokemon is based on/looks like, and I use the scientific name of that animal as the nickname for the Pokemon. It's a lot of fun!
*Average Joe:* Okay Science, what defines a species?
*Science:* Ehh... I'm working on it.
7th!
So a bee can mix with a buffalo mindblown
I thought the thumbnail was a reference about the breeding groups of Pokémon.
ITS A POKEMONNNNN
If pokemon were real, trying to figure out how they work would be a nightmare. I would love to explain how a slime monster can interbreed with a humanoid in a dress. At least you would never be bored in biology again.
Only here because of the Pokémon thumbnail.
Taxonomic sandwich sounds way better than taxodermic sandwich 😜
Oh noooooooo, I got clickbaited by Stufful...... and now I'm learning.... But WHERE'S MY BOIIII
Only 14 episodes? Bummer
Uhmmmm guys at @Crash Course are you tackling at Zoology THE FOSSILS 'cause i want to ready for my next grade..... ? Cause this is all about animals, right? 🤔🤔🤔🤔🤔🤔
Excuse me???? Final episode????? I feel like this series just started 😭😭😭😭
What's with this series and spiders?!
I am a simple person. I see Pokémon. I click.
NO I DONT WANT IT TO END
Pokémon
You used stufful for thumbnail. I would click
ayo
The thumbnail used pokemon again as a rfrence lol
i swear i clicked on this vid cause of pokemon easter egg :D
Should’ve used Bidoff as the thumbnail but oh well
So penguins emus eagles and ducks are the same species. We need to find the missing link for every thing on earth. This is what passes for science. And it can't be proved
