"Also the DNA system has a spell check mechanism, which corrects errors thus hindering evolution."

This is a fault of perspective. The DNA checking mechanism is a result of evolution because it better allows for successful reproduction. It is not flawless, and mutations still occur.

Flies demonstrate how simple it can be to make radical physiological changes with genetics. Scientists these days can easily change a couple genes around and a fly's leg will grow out of it's eye socket (and more)

[DomakChard]

Dating of a meteor believed to have formed about the same time as the Earth has put Earth's age at 4.5 billion years.

@RespectMyHate

Your jab at scientists frequently claiming to know the Earth's age is incorrect. There were uninformed estimations in the past, but no one claimed them to be definite. We now KNOW that radiometric dating works, because it has been crossed checked countless times a proven to be consistent by various other dating techniques.

[DomakChard]

@alarikmarcus

One small fault in what you're saying. Radiocarbon dating is not how the Earth's age is known. Carbon dating can only be used back about 50,000 years. The Earth's age is estimated by uranium. Scientist's don't claim to know exactly when the Earth was formed (it was a long slow process of aggregating hunks of rock afterall), but we have reasonable guesses. The oldest known rock on Earth has been dated to 4.2 billion years.

[alarikmarcus]

In actuality, it's not like Einstein even completely revolutionized science. Sure, his notion of physics expanded and improved Newtonian physics, but it's not like they completely turned science on its head or shooed it out the door. It's the same science, just clarified. It's more like a person with bad eyesight updating his/her prescription for glasses than anything else, probably. Science works by approximations and improvements, not by wildassed guesses.

[alarikmarcus]

So sure, I'd be perfectly willing to accept the notion that we could be off by millions or even a billion (or more?) years, but I think you fail to understand how radiocarbon dating works (any idea what a half-life is?). More importantly (and readdressing the neutrinos), I don't think you realize how "revolutionary" (e.g., faster-than-light particles mean Einstein was wrong) means something different to a scientist than a layperson.

[DomakChard]

Also, I don't understand how a biologist that doesn't believe in evolution is allowed to have a teaching job... He could easily cripple his students with his warped view of life. Evolution is essential in really comprehending the fundamentals of why any biological process happens and in predicting what it will lead to.

[DomakChard]

@RespectMyHate

Biology classes show that evolution is possible and prove it on a micro-scale (the scale at which it actually occurs within time spans observable by humans). Tons of biological theory that has been proven correct is also based on evolution, but biology doesn't prove that evolution from one species to another does in fact occur.

Geology is the science that definitively proves that evolution from one species to another occurred. It's written quite clearly in the rocks.

[jetetete31]

I want to know the name of the piece of music with the violins....

[RespectMyHate]

I don't know how anybody can believe in evolution.

[Sparclen]

@RespectMyHate

I don't know how anybody could not understand that life can get more complex with the years, to end up at a great design.

[RespectMyHate]

@Sparclen OOOOOOOOOOK.

[supertrinko]

@RespectMyHate Learning about it could help you with that.

[RespectMyHate]

@supertrinko Yes I have taken just about every type of biology class got an A and I still don't believe in evolution. Its an insane theory, I even make my teachers look foolish when I question them about evolution.

[supertrinko]

@RespectMyHate I sincerely doubt that, especially considering the date listed on your account.

[supertrinko]

@supertrinko date of birth, that is.

[sacr3]

@RespectMyHate Evolution is happening today, if you actually did "take just about every type of biology class" they would show you examples of evolution in action to this very day. How the very first cell came to be so complex, had to say, but how multicellular organisms got to what they are today is basically fact.

[RespectMyHate]

@sacr3 I did take biology and I'm currently taking microbiology, and it's funny because my microboiology teacher doesnt even believe in the theory of evolution, everytime we come to a slide that discusses evolution, he skips it. And he has probably been teaching evolution longer than you have been alive, certainly been teaching long than I have.

[alarikmarcus]

@RespectMyHate What kind of sad strange little school do you attend? Or is that a state school problem now?

[RespectMyHate]

@alarikmarcus These systems didn't evolve.

[alarikmarcus]

@RespectMyHate So you are instead proposing a solid state/ created system, then? How old do you propose this system is?

[RespectMyHate]

@alarikmarcus I believe God created everything the way it is. But because there is sin in this would all life forms degrade and die. I believe God created a lot of things, But I don't know the exact ages of them. One thing I do believe is that the earth is in the 6000's of years old. All of this is just my opinion. But really I don't see how any biological system could have evolved. Also the DNA system has a spell check mechanism, which corrects errors thus hindering evolution.

[alarikmarcus]

@RespectMyHate How does "spellcheck" (preventing completely nonfunctional miscoding, such as deletions) prevent traits from being passed on in recombination? The difference between a natural banana (with large pits/seeds in it, and not particularly tasty) and an artificially selected one (the ones you eat) is only one NATURAL mutation and a bit of differential reproductive success away from being barely recognizable.

[alarikmarcus]

@RespectMyHate But so you do believe that the world is only 6000 or so years old, not upwards of hundreds, millions, or even billions of years old? So you're suggesting that all modern radiocarbon dating experts (e.g., uranium-lead dating), many chemists, physicists, and biologists, all of paleontology and astronomy, geology, archaeology, and anthropology are all wrong, while one particular book written before men understood the earth revolved around the sun is right?

[alarikmarcus]

@RespectMyHate ... Let's not forget, as well, that Pope John Paul II said "Today, almost half a century after the publication of the encyclical, new knowledge has led to the recognition of the theory of evolution as more than a hypothesis." 15 years ago. More importantly, the same science that gives you modern medicine and technology (including electricity, your TV, radio, computer, and nuclear fission) is the same science that has concluded that the earth is old.

[RespectMyHate]

@alarikmarcus Science is right about some things are wrong about others. To say science is dead on about 100% of it's knowledge is absurd, I mean a few years ago it was thought that nothing come travel faster than the speed of light, now look. And as for the pope believe it or not but he is one for the most evil men on this planet. look into the history of that organization. I'll believe in God because this universe and things therein look designed by a mastermind.

[alarikmarcus]

@RespectMyHate I'm not saying I like the pope or Catholicism; I'm saying that even the pope concluded that there was a lot of (convincing) weight behind the theory of evolution. And of course it's not dead on about everything; it's only been around for a few hundred years, depending on exactly when you pinpoint the development of the scientific method. I don't find practical fault in the notion of a creator, just in the rejection of the obvious age of the universe and evolutionary processes.

[RespectMyHate]

@alarikmarcus Look I'm saying that science is wrong about that age of the earth based on their dating methods, a few Hundred years ago the earth was 10000 years old, then 100000 years old, then 1000000, years old then a few billion, what does this show? It shows that mans ability to date the earth is flawed. Whatever though, if you want to believe it go ahead, I'm sticking to my guns though.

[alarikmarcus]

@RespectMyHate In 1633 Galileo was ordered to stand trail for DARING to say that the earth was not the center of the universe. In 1862, William Thomson/Lord Kelvin calculated that the earth was 20 to 400 million years old, which biologists and geologists already thought was too SHORT. That's a huge difference in worldviews in less than two centuries.

[farayman3]

@RespectMyHate I'm sorry but something like evolution explains a lot more than creationism. That is just shifting the problem... It sound old but there always is the question, how did god come to exist. After all, religion was invented in the dark ages so that people could 'explain' thing that they didn't understand. (First form of since maybe...)

[RespectMyHate]

@farayman3 God always existed, He is eternal. Something always existed, so this ever existing something is God. (It's really not that hard to understand)

[farayman3]

@RespectMyHate Oke.

very cool vid but would be so much better if there was narration!

[guyonanisland]

tht was pointless

[19Tranc3r92]

@guyonanisland

What are you talking about? There's so much said in every frame.

[Scofield0085]

Thank you so much Drodybum! This is just amazing.

[Diego0402]

Nice video!!! now it's clear to me lol

[ChelCAC1488]

Watching this video makes reading the material afterward so boring in comparison... Great job.

[cutiephotographer]

Perfect! I envy the students who been taught with this kind of quality materials.

[Scofield0085]

wonderful.

[Sunshinespray]

wow that's wonderful: images, sounds, contents.. everything ! Thank you guys!

[Tricklabor]

The sound design from 1:05 to 1:40 is excellent.

[saylok2000]

how cool is that!!!

oooooooaaaah wh00t

[Scofield0085]

Motor proteins are badass.

[fbt2007]

Excellent!

[LandTeen]

wonderful achievement

[JXNashashibi]

those were probably kinesins or dyaneins, a motor proteins that walk on microtubles to transport vesicles throughout the cell.

[Cmann600]

What the heck were those things that looked like they were walking???

[HerbyTom]

my biology teacher said it was a theory that they moved in a walking motion? ye it does seem stupid

[cardiganclub]

look up what scientific theory means....

this is what actually happens. there have been experiments showing it.

[UneCecile]

Motor Proteins e.g. Kinesin and Dynein. They 'walk' across microtubules to 'travel' the cell.

[cardiganclub]

motor proteins

[jmm1233]

they are so cute

[asimplecapsule]

This is great. It's always really incredible to see analogs of macroscopic phenomena (walking) in molecular level structures (motor proteins). I don't know why. It just gets me going. ATP synthase is the same way.

[semiautosyclone]

ATP synthase is my favorite.

[piccololiang]

very very very good

[gaiamdp]

Daniel you are a genius, this is really fantastic!! Congratulations to you, to Thomas (great sound!!) and Toby also, a very good performance!

Perfect video to understanding the vesicle transport with the motor proteins (dynein-kinisin)

5/5

[Drodybum]

thanks, ...and myosin. In this video i show the movement of a vesicle along actin filaments driven by the motorprotein myosin.

[foresigns]

Absolutely excellent!

Great job!!!
