Carl Sagan - Cosmos - Artificial Selection

[baillou2]

Crab people, crab people. Taste like crab. Talk like people!

[anitkithra]

@baillou2 I just laughed so loud



[notfree25]

That is one creepy child king...

Looks like a wood dummy

[SuperGreenperson]

Those silly umans and their crabs...

[Apeshavenotails2]

What are Yoomans? And no I'm not a crab.

[TheLOCATION100]

Do Umans eat Erbs?

[Everfrost1000]

Umans seem like interesting creatures, I'd like to meet one.

[robertosixninesix]

he reminds me a lot of richard dawkins

[alexsolosm]

Agree with the comment below. But still, you can still watch this video for its concept despite its inappropriate example.

[Longover1986]

This story or "proof" was already proven to be false in 1993...

(Google "Samurai Crab" to do your own research)

So although it was heart-warming, it is not true and shouldn't be propped up by you die hard sheeple *cough*. Come on people, do your own research and stop treating science like it is a religion that cannot be questioned.

[MillyVanillification]

@Longover1986 The fact that someone claims that this story isn't true doesn't make it not feasible. However, domestic cows, pigs, chickens, dogs, cats, goats, sheep etc. do exist and the selection process still goes on (of course not for people in cities who dont know shit about farming and breeding in the first place). And it works in the same way as described in the story. Let the ones with the properties you like replicate, and eat/kill all the others. Simple as that.

[parusatereatsnuts]

@Longover1986 It's not 'false', just wrong. At the time of filming this was accepted. Science is self correcting, hence why we now know it's not true. You don't have to be condescending when correcting with more up to date data, it's very unscientific, more emotive and, dare I say, egotistical.

[xentius1]

@Longover1986 The story wasn't true, but I don't see what that has to do with the educational benefit in using it as an example of Artificial Selection. Greek Mythological figures didn't exist, but are used to explain things to laymen often, and that is precisely the purpose Sagan had for Cosmos. Teaching the masses in such a way as to make the content easier to understand.

[Bhikshu2]

Well no WONDER the Heiki lost the battle. Most of their warriors appear to have spent the battle attacking bamboo chutes.

[grimtendo]

@Bhikshu2 They also left a 7 year old boy in charge of their entire army!

[TheMrDressup]

Umans

[mefruh]

Deus comunga a matéria na essência mística da própria Criação, com este pacto, assegura a inviolabilidade sobre mesma. As Profecias e os Profetas existem para que Deus faça a comunicação entre o plano cósmico e o terrestre, a 28 de Setembro de 1978 ao Vaticano o Papa João Paulo I morreu inexplicavelmente para ser criado em novo PROFETA, A INTER-COMUNICAÇÃO ENTRE CREADOR E CRIAÇÃO. A 31 anos tenho buscado compreender Deus. Mais é por minha literatura que o intercâmbio é estabelecido.

[zanderthaw]

When Carl Sagan died I wonder where he went...

[derekxnl]

I've noticed that so far this video has zero dislikes. This makes me very happy :)

[BJ219]

@derekxnl noooooo you've jinxed it!

[VexT916]

Ken Watanabe a fisherman! 5:08 WTF?!

Am I still residing in Inception?! haha

[WOWJBEOWULF]

There is no artificial selection outside of DNA manipulation, even humans are living creatures, and the environment influences us as much as we influence our environment: Even being food is a species survival trait as chickens produce an egg each day--DNA survival trait. I have seen this effect Carl Sagan discussed, some Hippos in Africa produce the image of naked bathing women when in the water by their skin coloration--shadows like truckers do with the silver woman.

[machinaeftw]

Fine and logical explanation, but this does however raise the question; why do ordinary crabs not have face-like shells? Granted, that would make it useless, because if they all had faces on their back we'd still eat them.... but still :p

[truthiness2010]

@machinaeftw It raises no such questions. If a crab elsewhere grows a carapace slightly like a face it is of no advantage, wouldn't be noticed, and the trait is bred out. Why are wolves not born that look like bulldogs?

[mccarthy155]

amazing

[xp0nd3r]

not sure why you people cant comprehend what he is saying....

[Nascentthinker]

It might be that they are more into pseudoscience than science... Oh, that Carl Sagan would be distraught.

[Camil2221]

i think this guy is on crack. im like 100% sure this is natural selection. ok yes the humans are the ones in charge of selection but there goal wasnt to produce a hybrid specie or a complete species of crabs with that face. if you take for example the pepored moth, the dark ones who lived in a forest of white trees where eaten by birds, but the white ones had an adaptation and could hide so they werent eaten. thats natural selection. so why isnt it the same with this? the adaptation is the face

[standdownman]

He's not on crack. He just smokezweederrday.

[DeadCellsPhantom]

AS is a form of NS, however AS can be defined as any time humans get involved in the selection process, as opposed to just leaving species to adapt to their environment(NS). Breeding(intentional) is not the only kind of AS. Unintentional, as we see with these crabs, selection is still being made by humans, and thus AS.

And he's not on "crack"; he simply had a better grasp of the subject than you obviously do.

[Vennificus]

@DeadCellsPhantom actually he smoked weed

[DeadCellsPhantom]

@Vennificus Crack. Crack. Crack. Weed.

Weed?

[Vennificus]

@Camil2221 the peppered moth was an accident, this was more, on purpose. The more you looked like a human, the less likely they are to eat you, not because they think you are human, but out of abstract tradition

[Camil2221]

i did my research on artificial selection and yes i was wrong. i am 100% right in my resoning. the only difference between artificial selection and natural selection is that the human came into play during the selection, thus it is the humans who is involved during the natural selection.

and i dont get why you say that the peppered moth was an accident? how can it be an accident? i dont understand.

[Vennificus]

@Camil2221 Because we didn't choose it. The factory causing the tree bark to darken was not our intent, nor did we pay much attention to moths. The crab here was picked up and selected by hand, the peppered moth a biproduct of our passing

[Camil2221]

ok ok i understand wat you mean now. i didnt know you were talking about the factory here, wat i was trying to say wasnt with the factory, i wasnt implying that it was because of humans that came into play of their natural selection.

[TheLamelyNamed]

"other favors to the fisherman"

HAHAHAHAHAH, OMG, LMAO.

I think we all know what that means. Carl Sagan you playboy scientist you.

[ZplitSilver]

lol

[TheLamelyNamed]

HAHAHAH, omg, this is so painful to watch.

Painful as in odd and stupid.

Carl Sagan should've used a better example and better actors.

[acerb45666555]

2- watch>>>>"Kwaidan". for battle scene.

[acerb45666555]

the Heike Clan! they fought to the bitter end! not backing down one bit! theres a good scene of the battle in Hoichi The Earless.

[8DannyBoy]

it seems the same as natural selection to me. they have a specific trait that allows them to survive, even though its a little more complex than superior ability

[pooperuber]

humans are a a part of nature there for this is natural selection

[camino15]

its is like natural selection, hte difference is we are making the selections instead of nature.

[Crims0nBehelit]

Sounds so obvious, yet so many still don't get it. Saddening really.

[emoturbin]

Ya i understand too. They got rid of the yummy ones and kept the ones that they wanted alive.

[DrinkSkateSleep]

@Crims0nBehelit Saddening? It's gotten to the point where it's pathetic..
