Brainy & Brainless Animals: Crash Course Zoology #5

[@traildoggy]

Humans: "We are the crown of creation." Octopus: "I can think with all 8 of my arms."

[@patricksarama4963]

“And I have 3 hearts”

[@Luziferrum]

Octopus: You think you're smart? Don't hold my beer, bc I have plenty arms to hold it myself :D

[@timmy2870]

I loved the way intelligence was explained. This is a really important point to consider: animals are intelligent beings in its own way.

[@bythebeardofmatt]

I sound like a broken record, but this video was wildly entertaining, excitedly informative and wonderfully presented in a way that is easy to understand. Great, great job!

[@WaltRBuck]

This woman's presenting personality is perfect. She is extremely enjoyable to learn from.

[@VashdaCrash]

I think it's the first time I heard that we don't actually know what a brain is. If more of what we don't know was mentioned at education we could have more motivated students, sometimes is like we know everything to be known, and that may be discouraging.

[@piedpiper1172]

Bruh, we deadass spent all this time evolving, building big brains to use on tools just so fools could STILL comment “first” 5 times on every new video on the internet.

[@alvarodifini5017]

First reply!

[@bananaforscale1283]

Seems like an activity that would serve to develop their reaction skills, and then there are some who will only constantly complain.

[@Kraflyn]

@@bananaforscale1283 :D

[@randompheidoleminor3011]

The last time I was this early the _sun was still a deadly lazer_

[@epauletshark3793]

Oh wait, now there's a blanket.

[@LucasBenderChannel]

Taste. The sUNNNnnn

[@tatianatub]

hexagons are the bestagons

[@johnny_boi5456]

Yes

[@epauletshark3793]

I wanna comment, but I have no idea what to say.

[@romal-7895]

Ok

[@juniormynos9457]

Asking which animal is smarter is like asking which animal can move better.

[@felixthehuman]

At first at 11:55 I was like "how is that related?" then I was like "Oh yeah, barnacles are animals."

[@SpiderdayNightLive]

If this series does nothing else but let people know about the stunning diversity of invertebrate animals, then I will have succeeded wildly.

[@petercarroll7956]

Popppppppp

[@Thumbnailsquid5767]

Ms. Wynn-Grant is such a good teacher with great inflection!!

[@camiloiribarren1450]

Definitely love this series. So good

[@mariocesarsousa]

Thanks Rae.

[@MemyBurosi]

Loved it!!!

[@CMZneu]

Very interesting that starfish and others are in fact bilaterians(or descended from) at least evolutionarily speaking.

[@Thumbnailsquid5767]

love these brand new series !!!

[@Lucy-mf5gk]

Enjoyed the vid. What I got from it is...we have no idea😆 Animals are cool anyway.

[@rasmusn.e.m1064]

Ok, this episode made me realise two things: 1. I gotta look into these ctenophore thingies 2. Starfish are what happens when you slice a sea cucumber sagittally in five 🤯 (for real, I did not know they were bilaterians)

[@SpiderdayNightLive]

Learning about sea cucumbers legit messed with my head when I was designing this course. They are so weird.

[@akhragee]

Re: echinoderms -- look closely at 6:04. They're actually among our closest relatives, outside the chordates! IIRC from biology class, we share the developmental trait that when the zygote dimples to becomes cup-shaped, and then opens a hole to become ring-shaped, that second opening becomes the mouth (not the anus).

[@mtvtutoring]

Sea stars tried it out then realized brains just weren’t for them lol.

[@randompheidoleminor3011]

9:26 I think that the fact that bees need to be fundamentally light to be flightworthy also creates an unwanted bias. This might give the assumption that animals capable of flight are very smart when in reality us earthbound critters just have heavy bones lol

[@talideon]

Light *enough* for their method of flight.

[@charlieskerry-wallace9514]

Im starting to think that the animated man in these videos is supposed to be Frank Green.

[@josefernandopadillagarzon9543]

Grat information

[@j3ckl3r]

Earlier man had a larger brain than us , but that's because our brain became more efficient, so the brain got smaller. If 2 people had the same size brain, but one was smooth, and the other had many folds in it, it would make sense that the brain with more folds would be better, because it would have a greater surface area. So size isn't everything.

[@dailydoseofmedicinee]

The human brain contains approximately one hundred billion neurons.👍

[@jasepoag8930]

Why waste energy on big brain when small brain do trick?

[@Heregoesnuttin]

Insert some random world history reference to the Mongols joke here.

[@apurvanagoree768]

Quite interesting perspectives

[@bigt7706]

I've held a lot of honey bees that need assistance (hence my pfp), and they feel intelligent. Bees never sting me even though I handle them because it's almost as if they know that I don't pose a threat.

[@gibranhenriquedesouza2843]

The cow has its horns twisted.

[@1.4142]

Wonder if we can make animals smarter using artificial selection

[@stax6092]

"I have a Neural Net Processor, A learning Computer" .

[@srikanta13]

Octopus is the most intelligent nonchordate 😃

[@EyesOfByes]

This is kind how one could explain the difference between Apple's ARM based chip, and Intel's x86

[@talideon]

Having dealt with both kinds of processors since the ARM2 and '486 era... you've lost me. Modern amd64 processors have what are essentially RISC cores with a bunch of microcode layered on top, providing x86 compatibility and an on-chip VM to implement instructions that are harder/costly to implement with physical transistors. ARM processors have a much thinner layer, with a translation layer for things like THUMB instructions. However, neither architecture is "smarter". And if you bring up speed with ARMs being slower, that's only because the architecture's power characteristics lead to a situation where they ended up in a low-power niche that was optimised for. However, everything up to the ARM 700 was basically best of class speedwise, even discounting power consumption. The M1 is fast because it just went down the same optimisation route as the earlier StrongARM processors from before ARM processors became popular.

Tree's can live for hundred of years.

[@mmcharchuta]

Beeeez buuzzzzzzz

[@pookalobster3]

Intelligence is very biased and it was explained perfectly!!!

[@Erenyeager45478]

Rae Wynn-Grant is a nice name

[@averyford4432]

woah im early

[@roecocoa]

Would you rather play chess against a cat-sized dolphin or a dolphin-sized cat?

[@Thumbnailsquid5767]

it’s sight - we’re gonna talk about sight

[@Helpme-wp2tg]

I lost you at ganglia.

[@kus88]

zo - ology.... i've always said zoo-ology....i'm so dumb.

[@srijalsrivastava5164]

I 🤔 bee

[@ontario996]

First!

[@oxygenwarlord9277]

HEHEHEHEH 5TH TO COMMENT WOOP WOOP WOOP WOOP WOOP WOOP WOOP 😝😝😝😝😝😝😝

[@anttibjorklund1869]

No.

[@chazz30000]

We do have very good and accurate theories as on how memories are formed and retrieved. Your beginning statements are reductive and are full of ignorance written in just to make a "oh woe us humble humans we know nothing of this world" bullshIt

[@thedolphinqueen6474]

First!

[@romal-7895]

Ok
