Introduction to Biology: Crash Course Biology #1

[@vlogbrothers]

Very grateful to Dr. Sammy for keeping the Aristotle jokes alive. So excited for this series!!!! -John

[@johnchessant3012]

hi John

[@Teo117]

😁😁😁

[@jakefrechette3224]

Y'all have found some amazing hosts over the years and Dr. Sammy is absolutely no exception! I am really looking forward to the rest of Crash Course Biology 2.0 with them!

[@Joe-nh8eq]

I'll admit I was slight disappointed when Hank didn't appear, but damn Dr.Sammy absolutely crushed it. Fun, oozing with passion... Good stuff. Look forward to reviewing the wonderful world of biology with you.

[@elstankydank3815]

I Iiterally just finished Hank's edition of Biology crash course and now I hear there is another 50 episodes?!! I am here for it❤🤓

[@Snailgodonion]

Finally a remake of the classical series. I’m really looking forward to all future episodes! Almost got my bachelor’s in biology, so this series will surely come in handy if they go deep enough into detail. Hopes are up! I’m cheering you on Dr. Sammy!

[@drawyourownlife]

Used the old Crash Course at the time it came out and was a biology student myself. This new version is refreshing, yet I feel it's more oriented to highschoolers. (which is fine, I will this when teaching) Maybe it's because I'm older, or because this first ep is just introducing biology, I'm curious how it will grow further. So thanks for making a wider oriented version of Crash Course!

[@WCOBDisorder]

I did too when I was in High School, and next year I will be teaching AP Biology. So many great resources for the next generation of science students!

[@starch7993]

Dr. Sammy is SUCH a favourite science communicator of mine and as much as Hank will be missed, Sammy introduces such a new and engaging style of teaching and I'm SO insanely excited. Got me coming back to crash course for the first time since high school!

[@RogueWolfArtist]

Bright & Cheery narration style is a hard thing to nail without it being grating and no one did it like Levar Burton, and you have channeled him to near perfection. Great work, man. Never change.

[@secondstar101]

This!

[@OlTrev]

Yes I said the same thing!

[@strange_thing-arra-3692]

YES im so happy that the newer crash course biology is here! Although i do miss hank, this guy teaches really nicely

[@G-Tarun]

I first saw Dr. Sammy on Khan Academy's new Biology course, and now on CC Bio 2.0! This intro is so masterfully crafted and delivered - I can see how you learnt from the best of Crash Course innovations across subjects, and combined it with Dr. Sammy's gift for teaching all things life in his inimitable, engaging style! This structure of listing out the characteristics of life without sounding like a monotonous textbook - it makes me think a similar format could be followed for a Crash Course Consciousness/Cognitive Science, if you do eventually make it! I do suggest a 50-episode Consciousness over a shorter CogSci series, since it's important to understand it from as many perspectives as possible - global philosophy, neuroscience, psychology, evolution, linguistics, comparative behavioural biology, etc. Also maybe a super-applied Behavioral Science course too, focusing on how psychology-meets-economics-meets-ethics helps us build a better world.

[@unknownscryptid]

crash course biology helped me out so much in high school. I'm a biology major in college now doing undergrad research this summer and was just joking yesterday about how I may need crash course biology. impeccable timing

[@niecchan]

I studied biology in university and I am so loving this video! Thank you Crash Course. May you always be successful!

[@shrimpytcoon]

What is life? life is pain

[@Jaaxfo]

Baby don't hurt me, don't hurt me No more

[@hansolowe19]

Painnnnnnn 🤌😠

[@ashog1426]

Baby don't hurt me don't hurt me no more...

[@emilytopham5069]

Anyone who tells you any different is selling something --The Princesss Bride

[@AmyraCull]

Can confirm

[@DavidTullyPhD]

Dr. Sammy is going to be a standout host. Excited for this series, despite (especially because?) the time between now and my last bio quiz can be measured in decades.

[@davidsubotic9239]

Thanks!

[@doomedmessenger]

He's a really good pick for this Biology-redux. Think he's one of the most Hank-like presenters so far, which is a compliment to him. ^^ Love his energy. I'll be keeping an eye on this Crash Course session.

[@EyeLean5280]

The Hank Green CC Biology series is a tough act to follow - but they clearly picked the right person to do so! Great episode, and I'm so looking forward to the rest of the series!

[@ernestopreciado4895]

I very much like the definition of life that Hank onces gave in Dear Hank & John, "something is alive when it needs something, and then does something to get it"

[@tammyt3434]

"Are you breathing right now?" Me, chugging caffeinated tea for dear life; "Thankfully, no." And that, too, is biology.

[@alexreid1173]

It’s so nice to see an updated series! I watched these when I was taking biology in high school. I’ve taken a lot of college biology and ecology classes now, so it’s cool to watch these from a new perspective. (PS: updated, full length ecology series? would love that)

[@ShakalDraconis]

I personally prefer one of the newer approaches to the whole "are viruses alive" question, viewing the infected cell as the actual organism, and the viral load as the means of reproduction. In this way the virus is more akin to a mote of pollen. Now PRIONS, THOSE are the TRUE edge case!

[@gee8419]

Personally my college virology teacher told us to save the question of if viruses are alive for our philosophy classes 😂 Virologists routinely refer to a virus as alive if it is capable of replicating.

[@ClementinesmWTF]

Prions and self-replicating RNA/DNA are definitely the edge cases. Viruses I think should be redefined at least as a part of life, if not organisms in their own rights. The definitions of “life” are much like definitions of “species”: sure, they may seem obvious on the surface, and many definitions do align, but there are so many differences and edge cases for each that it may just be better to be as inclusive as possible while noting the intricacies rather than excluding and making half-excuses for why the definition includes this but excludes others.

[@venkatchait007]

you can also just think of host cells as the viruses environment, as a chemical system the viruses reliance on the existence of host cells is really no different from our reliance on the existence of an atmosphere or plants reliance on sunlight.

[@Human-san]

They're also really scary...

[@ananya.a04]

I love CrashCourse. It’s a lifesaver for me when I want to revise important concepts quickly. Even though I miss Hank’s narration, the new style is really charming too with the smart puns! Thank you to the entire team for bringing us such high quality content for free! Keep up the good work guys! 😊✨

[@clairematheson7153]

So excited for this series! I got my bachelors in lit but have been wanting to find free (and intro-level) resources to learn more about science. This is perfect!!!

[@ChimeraZone]

Hank is a legend, but Sammy is perfect for hosting this topic. Also bless you, Hank.

[@biointeractive]

So excited for this series! 💚

[@hc6628]

Thank you for remaking this series! I'm about to apply for teacher training specialising in Biology, even though my degree is in Psychology - so it's a perfect refresher that'll get me to where I want to be even faster! Keep up the amazing work, Dr Sammy! :))

[@KillerTacos54]

Dr Sammy did an incredible job in this video. This made me very excited for the rest of the series

[@JHaven-lg7lj]

I’m so looking forward to this whole series, it’s my first Crash Course!

[@clcsqueejy04]

I watched Dr. Sammy on his Wired interview and thought "man, this makes me want to learn so much more about biology." So I searched for a biology crash course, and here he is! I'm so excited to learn more about this subject from someone so good at explaining this subject.

[@seancreighton9154]

This is going to be one of the best Crash Course series yet! Cheers to science!👨‍🔬

[@luisvasquez9604]

I love the addition of Dr. Sammy, can’t wait to see more episodes!

[@amandanorton6508]

The new Botany series and now this! I love the new stuff they are putting out and I'm looking forward to episode 2

[@mitchilaine]

I am soo thrilled with this first episode! I think they're following a textbook (from openstax?) or just maybe the very beginning of biology. At school, we jump straight to cells and so on, so this was such a nice kickstart. I may not be taking biology(future pharmacy student here), but i sure am gonna love this series and love the subject even more.

[@johndoe-qo8cy]

What is life? Baby don't hurt me, don't hurt me

[@Yazan_Majdalawi]

He did not answer. Really.

[@ZosoLU]

, no more.

[@hand.2]

in my 2nd year of biology at university, this'll be a fun way to refresh my mind on the basics :)

[@nateweinand4209]

This is going to be a great series! Dr. Sammy is a great host!

[@funkykong9001]

I wish there was a way to get notifications just for specific CrashCourse courses like this one

[@AriaHarmony]

I love that you mentioned the connection to the reset of the universe! I like to think that everything is the hydrogen atoms from the beginning of the universe, fusing into heavier elements, and temporarily wearing different forms as time goes by.

[@MrARock001]

One of the most convincing arguments to me for viruses being "alive" is considering the virus particle itself as being only one phase of the organism's life-cycle. Like, the virus particle is effectively a spore from a fungus which can't do anything on its own, but needs to land in a suitable environment (like a living cell) in order to grow to maturity. The implication of that is that the true "adult" form of a virus is just an infected host cell, which has almost no other function than to reproduce.

[@feitocomfruta]

Not gonna lie, I thought they already did a biology course. But I’m looking forward to this one!

[@mbuhtz]

They did. This is a remake because Bio was one of the very first courses they did so long ago

[@JodyBrownIV]

they did

[@stuck_around]

waiting 12 years for this

[@strange_thing-arra-3692]

agreed lol

[@scottlott3794]

This guy sounds like LeVar Burton when he did Reading Rainbow back in the day. Gives me goose bumps!

[@johnchessant3012]

Finally! Now all that's missing is Crash Course Math. I guess math isn't really suited to this format, but I'd love a series on the history of math.

[@kebapgaming]

They could do a crash course calculus/trigonometry

[@AyoMakan2607]

Life is about surviving..surviving is either beautiful or painfull❤

[@Retronize84]

I recently got interested in fungi and thought it would be cool to see some other Biology videos. I remembered I used to watch CrashCourse ages ago and thought there must be a CrashCourse on Biology too so I looked it up and saw this was uploaded 1 day ago!!!!? What a crazy coincidence. The only downer is that I can't binge watch it because the next episodes aren't out yet >.< Really looking forward to this series!

[@summer37x]

Love biology, love your voice. I'm so excited for this series.

[@MarcoNicolasBongiovanni]

I already want the next episode lol, this introduction got me excited, biology is not my field of study, but I still love to learn about it nonetheless, also, I kinda miss Hank, but this host is awesome and really chill, I'm really excited for this new course!

[@kmcsciguy]

Very excited for the Biology series update!

[@amandanorton6508]

I'm obsessed with this

[@ensemblelearner]

NEW CRASH COURSE? LETS GO!

[@storm1968eu]

my favourite subject in middle school waaaaay back when ... 🌱

[@nathanespinosa3463]

Right when i finish my AP Biology class too

[@nawyaana1983]

this is my first time listening to dr.sammy and i think this course was very useful to support my educstion

[@Leotique]

Here for the new generation of Crash Course Biology

[@DracarmenWinterspring]

1:17 - I was expecting a note on how ants are obviously alive even though the vast majority of individual ants can't reproduce

[@ClementinesmWTF]

I’m very glad this video spent so long on the conversation of viruses as an edge case of life and why that is not entirely the case. There is much debate, and I think a lot of biologists are really just stuck to the traditional definitions of “life” when excluding viruses without having a further thought on it. Sure, they are very different from bacteria and other life, but there is no objective reason why we should exclude them when they are so much more like life than they are like a mote of dust. I hope to see that further explored (as well as self-replicating molecules like prions, RNA, and DNA) in the future of the field rather than just coming up with more and more intricate excuses on why we should continue excluding them from the definition of life.

[@ragnkja]

Could you please provide closed captioning for this course? It would help a lot of people, especially when captioning allows people to watch the videos at a lower volume.

[@Omni0404]

4:24 "Fourth!" Lol I love this guy

[@camiloiribarren1450]

I love this. This is what I got my BA in and love your lecture

[@christopher_graffam]

2:08 Bees don’t have livers. The Varroa destructor mites target the fat bodies of the honey bee. I’m kind of impressed that this wasn’t caught given that the host was on the team that discovered that this was happening.

[@Go4Noctis]

New crash course bio nice. Interested to see what we have to learn.

[@johnmcho]

I'm a big fan of host Dr Sammy!

[@RogueWolfArtist]

Been waiting my whole life for this.

[@Kiwironic]

Oh finally, I love this, no voice fry, but still fresh, cool and modern. Thank you

[@sarelvanwyk693]

Life is the most amazing thing that happened in the universe.

[@VinnieGer]

OH YEAH! LIFE BAY-BEE!!! PUMPED FOR MORE BIOLOGY

[@venkatchait007]

I like the NASA definition of life, keeping it simple is the way to go.

[@patrickmccartney2418]

It seems the question of “What is life?” is very similar to the question “What is free will?”

[@branhan215124]

Damn dude came out swinging- not since Phil Plait (imho) has their been a host on Crash Course who just oozed charisma from the word go, I am so psyched!

[@nietzschescodes]

Nice! A 2nd Crash Course Biology Series!! Great idea!!!

[@flamedragon07]

I am glad that he's rebooting biology.

[@nimbuscloud5175]

Genuinely thought/hoped this was voiced by Levar Burton at first, while not watching the video. Am disappointed it isn't, but Dr. Sammy does an excellent job and I love his energy!

[@IvartheScientist]

this was such a great intro video!

[@johnpepper-o7e]

This is a very informative video for educational purposes

[@redcaramel2222]

FINALLY!!!! Excited for this one. ☺

[@FrogOnALilyFrond]

Hehe this has me excited for learning and im not even in school 🎉

[@Mysterious-Night]

0:16 Nice June shirt you got there

[@Ella-gp5nx]

This is going to save so many people in AP Bio

[@floodedbrain9564]

it's here!! it's finally here

[@billyfox6368]

You're starting this days before my A-level biology exams. 😂😭

[@MakoWoman]

Brooo I’m so excited for this series!!!

[@Snaomib]

that’s insane i searched this and this video was JUST posted

[@The_Entity]

pmsl at the Barry White part. love how this is presented - really interesting. I'm starting a Biology degree at 35 y/o in sept and am trying to soak up all the possible information I can before then :)

[@June-ft1cb]

OMG Dr. Sammy is so awesme ❤

[@oopsy444]

i got so confused why theyre doing biology #1 when they already did until i realized im thinkning of pbs lol. funny how both decided to tackle biology almost at the same time. so glad they covered different stuff too

[@dragonetafireball]

Nice I was just looking for a basic biology refresher because I’m going into university for it so this is good timing

[@justjunkmale]

I've been trying to decide whether or not to go to college for a degree in biology and then this crash course starts. I might do it 🤔 the timing is wild.

[@5Seed]

I'm so pumped for this and botany. Loving getting back into crash course

[@dreadnought1109]

Guy gave me Levar Burton vibes. Excellent

[@kausikmr]

@CrashCourse I used to watch all you videos and I love it, CAN YOU PLS MAKE VIDEO ON NEUROMORPHIC COMPUTING.😃

[@hidingzeus4306]

This guy sounds so much like LeVar Burton, I honestly wondered for a minute. Awesome stuff.

[@windk2123]

i have learned a lot. thank you

[@shawnholbrook7278]

Hi Dr. Sammy! Welcome to Crash Course land!

[@ysdeepak90]

As soon as you can't explain, you prove your position. So called scientists & scholars are not yet clear on the defination of life!!!!! It is so amazing that we know so little about our own selves & yet we are so proud.

[@isacami25]

it was so interesting to see both this video and the one in spanish. I love that you're doing that, i can now show it to my nephews

[@elihinze3161]

This host is delightful!

[@james__anna_burns4885]

very excited for this series!
