@Erech01

In the process of criticizing another person for being wrong, you yourself were erroneous, fucking dip shit!! It's the contraction "you're" that you were searching for in your primitive mind but could not find.

Stop arguing with creationists, it will get you no where. Your sentence structure and grammar are hideous, you MUST stay in school if you ever want to become more than a waste of space!!! Haha

[Erech01]

@jumb0mumb0 I though we we're debating that facts, not my grammar. I'm a science student, not an English one. It's amusing that instead of trying to debate the facts (which you clearly can't do) you critisice my grammar. I only tend to worry about my grammar and spelling when i'm writing up lab reports, not on youtube....

[Erech01]

@Erech01 P.S. i haven't been at school for over 5 years, im currently at university.

[backroadjunkie]

Satan made the humming birds...all hail the almighty.

[zaxineohp]

I want to know how evolution really works. This video is just a repeat of the random variation and natural selection theme that is only an outline of what evolution must accomplish.

1. Where and when in the reproductive cycle does the random variation occur?

2. How is the body plan modified and where does it reside?

2a. Proteins have to be organinzed into tissues.

2b. Tissues have to be organized into organs.

2c. Organs have to be organized into body plans.

[giorgiv18]

i just looked here to see the comments. and i wasn't wrong: the video is mostly commented by complete idiots, who are trying to convince each other that their point of view is the right one. new scientific discoveries are constantly made, the truth changes over time, so why should we let it influence our lives? seriously people, don't you have anything better to do than discuss evolution on youtube of all places? now I'll navigate to another video discussing evolution and see if it's the same

[NIKOWRITER]

Would I be able to get a high resolution version of this video??

[Siteswap33]

So... how does one species become another?

[Drfarahmo]

Many think the holy Qur’an is a book with no real connection with credible science. This is not the case. The holy Qur’an described facts 14 centuries ago proved to be correct in this eBook that describes the origin of life. This is the first exhibit in history utilizing core and advanced biology about HOW human creation happened from clay. See the credibility of the holy Qur’an. Search for: decoding human creation

[gorilla199uncensored]

@Drfarahmo

"Qur’an"

LOL yes tells us salt water doenst mix with fresh water! LOL

It also missed evolution, etc etc etc

[xbroadcaster1991]

@gorilla199uncensored Hi, the Koran said that salt water doesn't mix with fresh water because God has created that pool in such a way, Now of course there's scientific explanation for that. How is science contradicting with science? Just because the creator doesn't provide the evidence except guidance through prophets doesn't mean the creator doesn't exist.

[gorilla199uncensored]

@xbroadcaster1991

"because God has created that pool in such a way"

Good to see you make excuses to pretend the koran is correct, unliek the ol;d days when the muslims knew the salt and fresh water where kept sepearte because their primative story book claims so.

[xbroadcaster1991]

@gorilla199uncensored lol many Muslim scientists researched on it to find scientific explanation since 9th century. Of course they didn't have the equipment and instruments to test that pool. You won't find any Muslim who claims that everyone in Koran has no scientific explanation. Koran says that earth has 7 layers does it mean science can't discover it? Guess what science did and they are 7. Koran says that the womb of the women has 3 layers and guess what! Science proved it right!

[gorilla199uncensored]

@xbroadcaster1991

"Guess what science did and they are 7"

Provide reference and name the 7 layers

"womb of the women has 3"

Wrong

Science still hasnt proven the world is egg shaped has it? LOL

[xbroadcaster1991]

@gorilla199uncensored Egg of an ostrich btw.

The outer core

The lower mantle

The upper mantle

The D" layer

Transition region

Continental crust

Oceanic crust

[gorilla199uncensored]

@xbroadcaster1991

" Egg of an ostrich btw."

Yes which is not anything like a sphere.

Whats the koran reference? As asked!

7 If we count one sub section and the atmosphere! LOL

[xbroadcaster1991]

@gorilla199uncensored Koran is not a science book. It's a book of signs and guidance. You have the freewill to accept it or not.

[gorilla199uncensored]

@xbroadcaster1991

"You have the freewill to accept it or not."

I dont believe such crap and nbeither would you if you where not brain washed into it as child, would you?

[xbroadcaster1991]

@gorilla199uncensored No one is born with a rejection of God

[gorilla199uncensored]

@xbroadcaster1991

"Koran is not a science book. "

Now you admit its wrong, when I point out thats its wrong, before you claiming its right and only g od could have done that! LOL

"No one is born with a rejection of God"

What are you on about?

[xbroadcaster1991]

@gorilla199uncensored when atheists say that every child is born atheist they're wrong.

[topbluffa1]

creation and desturctions are both myths.

try to create somthing from NOTHING.

and try to turn somthing into NOTHING.

you cant do it.

you cant even destroy 0.1 gram of somthing no matter how much you smash it up burn it etc.

it will be converted into smoke ash etc the mass that is lost is converted into energy.

[topbluffa1]

the first sell of matter came from a conversion of Energy into matter.

E=Mc2.

and the energy came from matter and its a cycle.

time is not constant so saying "but what happened before that" is not relevant.

just like the sun converts matter into energy to create light.

energy converted itself into matter.

because energy and matter cannot be destroyed only converted.

[Jcm9991]

But surely for each beneficial genetic mutation there is going to be several harmful mutations that will seriously screw up the organisms genome and will basically make the beneficial one useless.

[alfuentesev]

@Jcm9991 Many mutations are neutral and irrelevant at the time that they occur - they can "lurk" for generations, masked by other dominant genes until some point at which they are expressed and produce an effect, for example, against a new virus that kills off members of a species that lack that one particular mutation. Just one example, but the selection of genetic variations needn't happen at the very moment when they are introduced in the genome.

[L337EE]

Why hasn't scientists test a family of generation that has been vegans. See studies on how they change over the years. I'd like to see something studied and how it will change human behavior, strenght, growth or braincells. INTERESTING ANYONE?

[Chilango808]

I live in Hawaii and it's really hot as hell here... Does that mean that I will inherit magma? or do I live the way i live right now? Now which one sounds serious?!?

[alfuentesev]

@Chilango808 It would help if you suggested a situation that could perhaps occur in nature, and which evolutionary theory might predict. As for human evolution, the effects of culture and technology have made us a special case in nature - we don't need to wait millions of years and tens of thousands of generations to evolve a special resistence to heat in Hawaii...we just turn on the air-con. Mind you, with global warming, humans might need to do some evolving after all...and fast.

[ShKitSo]

can someone explain how dinosaurs evolved into birds? how can a reptiles eventualy grow feathers due to struggle? :S and it cant be offspring because a reptile and fuckin bird cant fuck

[Bardlettt]

@ShKitSo Some dinosaurs already had feathers before they could be classified as birds. A feather is a modified version of a reptilian scale, and many birds today still have scales: just look at the leg of a chicken. Feathers may have begun as a display for mating. A reptile and a bird can't fuck because today's birds split of from reptilia a long time ago. Same reason you can't fuck a cow...well, I suppose you COULD, but I doubt the cow would appreciate it.

[MichaelMason9]

what about if an environment was to change quickly like we went into an ice age would the species around now evolve quicker or is evolution always at the same speed

[ErichoTTA]

My favorite in the series.

[abyssquick]

"fittest" for their environment.

the flowers are also replicating too. a shorter flower will allow better pollinization by a shorter beak. so everything is connected you see.

[anayama]

one way for single cell organisms to "become" multicellular (on a species level) is mutation. same for any crazy adaptation you might see. for example, the Delta 32 mutation. "evolution" doesn't necessarily mean "making it better." some species evolve themselves right out of existence. or into another.

[hiisyourdaughterhome]

one problem: having your bill grow over generetaions by an inch is one thing, but how do you explain dramatic transformations? a simple eye does not get little better over years to eventually become an advanced eye because the advanced eye functions on a different principle and involvs new sets of organs. it's like expecting a wagon pulled by horses to turn into a ferrari if you just keep improving the parts it's mado of.

[325982668]

and if you take 259 million years only replacing wagon parts with slightly less wagon-like parts and force wagons to mutate and pass on the mutations and the couple the mutations with a competition for survival, and ferrari is a successful result of these mutations and the right mutation happen that it resembles a ferrari,, then that is what you will get. remember, not all cars are ferraris and yet they can all accomplish the same thing. they're all more successful than wagons.

[nezahualcoyotl85]

there are no new parts just parts sightly diffrent or the loss of old parts. when the primitive eye looses something and changes anuther you get a new eye and when the creature mates with anuther creature with a slightly diffrent eye you get something more diffrent over time.

also the horse is seprate from the wagon wich is not alive and dosent change do to mutation. your logic is bogus to begin with its like comparing rocket ships to bannanas!

[PPartisan]

There was a simulation experiment on the evolution of the eye which showed how a complete fish eye could develop in a few hundred-thousand generations from only a patch of light sensitive cells using conservative estimates of mutation and selection. I can't remember the citation but it's definitely out there.

[mrpocock]

1. The first single cellular organism probably evolved from a simpler organism that wasn't cellular

2. We can see multi-celled organisms evolve in the lab. The standard models for this are green algae called Volovox. The standard selection pressure is grazing by predatory organisms.

[srkniss]

Answer this, why cant scientists bring fourth life fron non-living matter? Every living organism has DNA which is INFORMATION on the makeup of the organism. Who gave the INFORMATION to the organism? Amino acids do not form chains, they only break apart. If you study this with an open mind, not bias to either creation or evolution, you will easily figure out how impossible it is for life to come about by chance.

[Timely]

Read quantum mechanics. The theory of improbability.

That itself proves that "anything is possible", just not probable.

And to answer that, whether your an evolutionist or creationist, it is easy to figure out that neither has one base which they can branch off. Evolutionist is the beginning square from which they branch of, and creationist for the sheer inconsistent evidence they bring to the table.

[smaakjeks]

"Answer this, why cant scientists bring fourth life fron non-living matter?"

Because their laboratory is not the entire earth, and they don't have a billion and a half years to get results.

"Every living organism has DNA which is INFORMATION on the makeup of the organism."

Bzzzzz! Wrong.

"Who gave the INFORMATION to the organism?"

Begging the question.

[smaakjeks]

"Amino acids do not form chains, they only break apart."

Bzzzz! Wrong.

"If you study this with an open mind, not bias to either creation or evolution, you will easily figure out how impossible it is for life to come about by chance."

No scientist will tell you that life came about by chance. It is not what abiogenesis predicts.

[TheGreaterSatan]

"why cant scientists bring fourth life fron non-living matter?"

What does this have to do with evolution?

[lostn65]

Why can't God make more women from men's ribs, and men from dust?

[snylekkie]

taxes man, they're killing him.

[npaujbais]

Hahah!! :D Good comment.

[Aerosteon]

Scientists understand how the sun works, where it is, and what it does. Would you require scientists to somehow build themselves a sun before you accepted their research? Reproducing something is much more diffuclt than understanding it, and you can understand something without being able to reproduce it.

[tpritchard7]

for fucks sake, how can people still not get evolution!? these kind of videos make it so simple to understand and you still get retards wafflin on about "macro-evolution". put down your bibles and pick up a proper book for a change

[KT45]

When people think of evolution they think of something coming from another animal (a monkey birthing a human) or turning into another animal (kinda like evolution in pokemon). Of course these are gross misconceptions that are false. The only solution is to point out this misconception immediately. Guess we gotta make it even simpler.....

[tranhn]

This video doesn't show hummingbirds turning into another species of bird or reptile. It shows manifestation of variation and adaptation. To extrapolate that into macro evolution is insane.  It's nice to be paid to work in nature though.

[EziekielNightwind]

You can't walk a mile without taking a step.

There is no such thing as Macro and Micro evolution, there is just evolution.

As the video stated, small changes, over the course of millions of years, result in major changes.

[Timely]

Well that's not neccessarily true.

Macro Evolution exists only if the species is indanger and is in need of change. That causes pressure of adaptation which often leads to the extiction or progression of a type of species.

Micro Evolution is eventual evolution, which the species is slowly being pressure in accordance to climate or region.

[smaakjeks]

"Macro Evolution exists only if the species is indanger and is in need of change."

No, I'm afraid you're incorrect. Macro evolution is simply a term used at above species level. When a population speciates, this is called macro evolution, however there is no difference in mechanisms or principles. It's simply a term used for practical applications within science.

"Micro Evolution is eventual evolution"

Micro evolution is simply sub-species level evolution. It is evolution in a short time span.

[Timely]

Ah I see, well thanks for correcting me

[smaakjeks]

Spoken like a gentleman.

[Timely]

Likewise

[purpleletters]

Why would a bird turn into a reptile?

Evolution IS a manifestation of variation and adaptation, that's what natural selection is, didn't you see the beginning of the video?

[comodocomodos]

Even if there were evidence for God, Malaria is a product of evolution. Is that God perfecting his creation?

[aarongabriel2]

Gino I'm glad you accept evolution but come on wheres the scientific proof for god?

[cryptographix]

Thanks for the upload.

[Gino777]

evolution is just God perfecting his creations.

[kurtilein3]

prove that anything we see in nature was created by good. give evidence.

at the moment we already have lots of POSITIVE EVCIDENCE for the theory of evolution, so no form of life was created by god.

even if you prove gods existence (and you failed to do so) evolution is so strong that it still proves that god had nothing to do with creation. compete with that, monkey ^^

[Timely]

So your accepting the fact that evolution exists? Nice.

Simply by saying evolution is just God perfecting his creation, you mean, "Evolution exists, but it was God's work"

[raquelxoxo]

evolution is basically adapting to one's habitat through the generations.. what does god have to do with anything? i mean you can believe in god and evolution..i do at least. but i think they're two different things.

[homeborn]

Evolution does not require belief

[prospect25]

it doesn't but i believe in it. some people don't. it doesn't need believe, yes, but some people just don't believe in it. lol

[Erech01]

i think what he ment is it isnt a beleif system

[lostn65]

Evolution explains life sufficiently without the need for a divine entity. Occam's razor shaves off unnecessary entities introduced, in this case God. To assume his part is unnecessary and makes the theory less parsimonious.

[raquelxoxo]

i'm not disagreeing with you. it's just that i believe in it, whether it requires belief or not. am i worshiping it? no. do i worship god? no. And please, your surplus of vocabulary does not impress me.

[lostn65]

Fair enough. No one can stop you from believing what you want. My words were not intended to impress you, I was just stating things matter-of-factly.
