Carl Sagan's Cosmos Episode 2 part6

[CheffBryan]

Those are some SERIOUS chops!

[gbuffon01]

Organic molecules. Life's raw material.

[immortal4942]

ok i'm confused what did he create in that experiment? molecules?

[vlakieste]

One person can't comprehend biology, even after it's explained to them.

[adicakes]

Carl Sagan sounds like Agent Smith. 'Mmmisssster Aaanderserrrrrrrrrrrrrnnnnnnn.­..'

[ThatGuyWithHippyHair]

@EdJ343

Sagan already answered your question sufficiently. Much evidence from the DNA of organisms living today suggests that all of these organisms are related. We share an ancestor with trees, but it is very, VERY distant. As Sagan's simple explanation of the evolution of life on Earth showed, plants branched off from the organisms that would become humans fairly early in the tree of life.

[alejita1679]

The notes of the music of life sound like Mahler's Second Symphony "Resurrection"... very appropriate!!!

[aeropostalbaby1]

it's sad that retards like bieber and lady gaga get viewed millions of times by young people, but these amazing informative videos only get thousands. we need to get our priorities straight and put some sense in the ignorant heads of the youth

[EdJ343]

Why, uh, are we yuman beings, uh, cousins to the trees?

[meshuggahismylife]

Nice bong. Nah, just kidding.. but could you imagine?

[vmelkon]

pool of mercury!

[TheZAMBONILADY]

I WISH CARL SAGAN COULD HAVE STUCK AROUND A FEW MORE MONTHS TO SEE THE MARS ROVER CRUISING AROUND ON MARS. HE WOULD HAVE LOVED THAT. I CAN SEE HIM GRINNING AND JUMPING UP AND DOWN--LIKE I DID.



[SirNewt]

@TheZAMBONILADY Far to the left and halfway up your keyboard exists a key marked Caps Lock. If you could give that guy a single tap it'd be greatly appreciated.

[PsycCentauri]

@SirNewt - I think you are overreacting

[SirNewt]

@PsycCentauri Hold on while I regain control of my faculties.

[FFFurken]

@TheZAMBONILADY WHAT?

[SaySumtin90]

In this vessel are the notes of the music of life, although not yet the music itself.. Loved this expression

[pixeluded]

@Hullucinate1 great series! i also recommend it to sagan fans

[Shavarnarak]

Not true. Natural selection would, on an Earth-like planet, adapt lifeforms to suit their earth-like environment. And thus alien Earths would probably have something we'd call a fish and that looks reasonably like a fish for example. It's possible an alien Earth has a fish that swims like a whale. But it wouldn't have a fish that swims like a brick. Those wouldn't survive to reproduce well.

Alien life will be different, but recognizable I think.

[Shavarnarak]

@Shavarnarak

On Earth, creatures tend to be shaped the way they are for a reason after all. So on another Earth some of those shapes, or other effective shapes along the same lines will arise through natural selection. It's only logical.

Now if life arises on a NON-Earth like world it might be another story... If such a thing is possible of course. It may not be.

[2CSST2]

@Shavarnarak I agree with you, but they could still be very different in form. Think of the disappearence of dinosaurs, if it wasn't for that meteor (probably), earth-like crearures today would probably look more "lizardly" and very different. I think there are also lots of different ways life can survive. Think also of a planet with different attributes, for example a different gravity force, that could lead to things we have never seen here, similar, but certainly different in many ways

[DanteWhite]

this is so awesome i wish there was a tv channel only of this kind of stuff i love science  and im only 18 years old :)

[iraul20]

@DanteWhite I too am 18 years old and Carl Sagan is my hero. it is a shame that most kids our age don't think they can be smart or are too lazy

[GiLligEN]

@iraul20 It's not cool to be smart, sad but true

[kaballmo]

@GiLligEN It's not even about being smart, not everyone can be smart. I can honestly admit I don't have a massive intellect; I struggle to grasp the theory of relativity and I find that quantum mechanics is beyond my comprehension for the most part. I do however have a burning curiosity and a mind capable of skeptical inquiry. That's all one needs to begin to appreciate the true beauty of the universe.

[andywagoner]

very interesting. sagan's voice is nice to listen to.

[plato386]

Thank you Carl Sagan, long live the pursuit of the beauty of the cosmos.

I will always remember you.

[alexander224]

I'm a theoretical astrophysicist.

[nvidea8400gs]

"Carl Sagan's my homeboy" (He is the reason why i'm am now a theoretical astrophysicist)

[pkscolax]

Right on mate! I sure hope that's your day job and not just a hobby ;)

[TheVisceral89]

@nvidea8400gs

U go boi!

[nvidea8400gs]

I lie, i'm a four year student of mathematics/astrophysics, but hopefully I'll end up being an research astrophysicist!

The beauty about astronomy is that you don't have to be a scholar to awe and fixate on the immense beauty, the unsurpassed elegance; and innately humbling power of the heavens!

[PharaohsBrew]

i have a man crush on carl sagan

[gskaloyan]

If it's okay for Spoony to have a man crush on Kevin Sorbo it's okay for you to have a man crush on Carl Sagan.

[MrGHAMBA]

ben sucks darwin hairy monkey balls :p

[MrGHAMBA]

your point being ben is the biggest idiot of all the bible clan

[AboutHreinzi]

dint ben steins movie witch is pro creationism say that you could not create life like that

[itsjustadamnedname]

Carl Sagan died of pneumonia technically... but I don't know if it would have killed him if he hadnt battled for a good length with myelodysplasia... he had 3 bone marrow transplants.

Mayo clinic "..in the various myelodysplastic syndromes, the orderly and controlled production of cells fails at the most fundamental level — that of the stem cells. The immature cells are often defective, and instead of developing normally, they die in the bone marrow or just after entering your bloodstream..."

[nystagmus]

usually in those type of diseases, leukemia and even myelodysplasia (some hematologist oncologist regard it as a leukemia) you either die from bleeding or infection. it seems like you know what you are talking about, im just saying this to act smart.

anyway, its terrible because this man is just the realest. if i had a chance to meet him , i would not say i word, i would just listen.

[legoflamb]

"Assemble themselves" obviously there is an error in the words he used and is not implying that point. However, what randomness cause the organic material to combine to form life?

[arthenor007]

Carl Sagan did not die from cancer.

[crectenw]

Well, yeah you're right; technically he died from pneumonia which killed him due to immune system weakness from myelodysplasia, a rare form of bone cancer. His rare form of bone cancer was said to have been possibly caused by numerous trials of the experiment demonstrated in this video.

[awefaislfdas]

That is absolutely 100% false. Fuck you crectenw for saying that. Die.

[TransitionalHuman]

I'm not sure why nucleic acid could be a carcinogen. And carcinogen only cause cancer if your exposed to them for a length of time. Just one exposure isn't enough.

[shogun2508]

I wish there was an updated version of this show on TV right now, it be nice to see all the updated theories and progress made since the 80's. Instead we get shitty reality tv shows.

[festusthefiend]

You are so right.

Thats the reason why I havent watched and TV for the last 2 years or so..

[eightyocho]

You should check out Brian Greene's "The Elegant Universe." Not the same thing, but very interesting.

[FreemanFighter94]

@shogun2508 I don't think it could be as amazing without Sagan.

[iraul20]

@shogun2508 Next on 90210 Dillon's dick is one inch

[aswatful]

@shogun2508 brian cox comes near...

[JohnnyZenith]

AMAZING !!!!!

[fortress7373]

2:00 It's ALIIIIIVE!! No, wait it's just organic matter... Igor, tell your ancestors to watch for elementary living cells.

[Hereticbooks]

R.I.P. Carl Sagan. One of the best teachers we've ever had...

[feifeishuangyu]

wonderful

[happyface3457]

i like watchin videos like this. carl sagan rocks. ty for posting

[dragg17]

tell me why this kind of stuff doesn't have millions of viewers? Doesn't even break 10000 views. goes to show you where humans stand towards knowledge. So sad. truly sad:(

Carl rocks. i could trip out on anything and get blown away by this stuff. hahahahahaha.

hmmmm.....

[VelikiBedak]

See the number of views on sexual related clips. That is our primary biological role by the way, maybe that is the answer why only small percent of people are interested in scientific clips.

[dragg17]

Its nice to know that some of us can help it.

[darkedge21]

this is amazing

[terrasidius]

Carl Sagan is RULE! XD awesome man.

[YOURGOD78]

Carl Sagan is hero!

[SirNewt]

Lack of grammar hurts head!

[YOURGOD78]

Ouch! Yeah 'a'. I guess I need to start paying more attention.

[kwolf002]

Articles are overrated...

[projectbrumaire]

@SirNewt How arrogant.

[projectbrumaire]

@SirNewt How arrogant.

[lukeism2]

@YOURGOD78 HULK SMASH!

[JRod8885]

@YOURGOD78 YOU'RE WINNER
