***** What do you mean Atheists? Tonnes of religious folk (myself included) believe in macro evolution. You do realise that the literalist interpretation of christianity is not the only one followed throughout the world and that believers of other faiths also believe in macro evolution. You can obviously speak for yourself but don't go speaking for other people. That's just rude.

Greg. Sym. Okay, we are getting off topic. The point has been made that Cody Cotten isn't self-identifying as an atheist, so let's get back to the interesting stuff. Creationist scientists think that organisms can change but cannot change species. Each species has a certain # of chromosomes, I think humans have 46. An organism in the dog species can "evolve" into 4,567 types of dogs, but never into another species.
@Moman893
@Moman893 9 лет назад
ObieMe1 this is where evolution gets interesting. Scientists ran into a big issue with the number of chromosomes humans and apes have. Apes, the cloest living organisms to homo sapiens, have 48 pairs of chromosomes, the ONLY way apes and humans could share such a close ancestor is if there was some possible way a chromosome disappeared (not possible as far as I know), so they predicted they'd find a fusion between two chromosomes in humans, and it was discovered. HUGE evidence for common ancestry.

That's not surprising at all. You type with emphasis, as though that's something special or interesting. However, many fundamentalist Christians and southern Conservatives in the US become Biology teachers or get Biology degrees so that they can create that same effect. Some a fundamentalists also become Astrophysicists so that they can claim an Astrophysicist doesn't believe in the Big Bang. Your teacher's situation isn't special or unique. They do that on purpose. It's part of their mission, and they view it as missionary work for their god. There are also some racists who become biologists by getting Zoology degrees, so that they get credit for being a Biologist who believes one race is superior to another. Your teacher isn't actually trying to understand Biology in it's fullest, your Biology teacher is just trying to use their status to convince people. Many of the religious Conservative schools realize they need to fill positions to be accredited, and Biology is one area they need to fill. Some don't hire liberals or people interested in education, and quietly hire only religious people. Some schools that aren't aware of what fundamentalists do will hire people no matter what, for the sake of filling spots to educate kids, and they don't realize that missionaries are infiltrating their schools. Could you imagine someone teaching Physics, without believing in the Scientific Theory of Relativity? It doesn't make sense, right? But ANDREW SCHLAFLY, son of Conservative loon, Phyllis Schlafly (who fought against the Equal Rights Amendment for women), Andrew author of Conservapedia, Andrew fighter of ObamaCare and health care for all, Andrew believer of Noah's Flood even though the pyramids have no water damage, Andrew who was in the same college class as Obama and has a degree... Andrew Schlafly home schools students and assists them in their science classes, but he believes Einstein's Scientific Theory of Relativity is a "liberal hoax". ..... (The reason he believes this is because it's the only way to solve the fact that light has been travelling from some galaxies for longer than 6,000 years to reach Earth, and the Bible requires him to believe that the Earth is 6,000 years old. Since he believes the Bible is true, then he believes that proven-true science is wrong. Instead, he should accept that Einstein's theory has already been proven, and that the Bible is wrong. He can't accept that.) So there's nothing special about your Biology teacher denying the fact that Evolution is true. Just like Andrew Schlafly, your teacher is in denial.

@seveNbrhIck
@seveNbrhIck 8 лет назад
Mrinalini Person Well, I considered that you might not live in the US (which is why I was specific about that, since you never know who you're talking to on the internet). I typed that from my phone, so I didn't check your profile to see where you were from. But, I'm at a computer now. So Mumbai, huh? Is your teacher a follower of a specific ancient Indian scholar? (I know that foreign people often combine them together and just call it "Hinduism", but that people follow different scholars, like religious divisions.) It's interesting that this same argument is apparently going on in India. It shouldn't even be an argument. In several Conservative Muslim countries, they're also fighting against any teaching of evolution. Richard Dawkins did an interview with some Muslim students in a classroom (in an Islamic country, but I forgot where). The students said they don't believe it, and they started using old bad arguments that American Christians used to use (but stopped using, because they were bad arguments). I think one of the arguments was "If humans came from monkeys, then why are there still monkeys?" ... Uh, we didn't come from monkeys, we came from Homo Erectus, which is extinct now. But even if they hadn't gone extinct, it would be because they don't just all agree to change together. Some change, others don't. So obviously you realize that evolution happened (and continues to happen). I assume that your Biology teacher is still teaching it, even though they don't believe it? If you want to study it a little further, check out the website "Khan Academy" (they've got lots of free online classes, not just Biology). Khan Academy is a great resource. "Coursera", too.

@@user-JJJJJJJJJ Mutations occur individually. Natural selection guides the mutations in a population of these individuals. So, a lizard won't give birth to a non-lizard but a population of lizards may change as in the likes of a ring species. As for an analogy, think of the way languages evolve (taken you don't think it came from the tower of babel); populations diverge and small words change in the language which adds up over time, and the isolated groups have different languages that come from the same ancestor language (like Spanish and French both came from Latin), but you do not get a Spanish speaking mother giving birth to an English speaking kid...as for as forming the languages. Hope I helped!

@@darklogic6998 thats funny i too thought about this more using language as an analogy. i gather the part that still eludes me is just like you said about how a lizard won't give birth to a non lizard so then at what point and how is it possible that we have all the different species or families we have today? did each like "genre" (apologies for my ignorance on the correct terminology) of creature get a start of their own thus lizards always making more lizards meanwhile canines having their own separate start always making more canines? or does every kind of creature we have today have a single common ancestor? and if they do how did that ancestor (for lack of better example and for sake of simplicity) birth a non lizard (or ya know birth a non whatever that common ancestor was). or did all creatures starting from that common ancestor just slowly go off and do their own things so one group became lizards and this other group became whales and then this other group become plants? am i making sense cuz i feel like i lost myself haha
@darklogic6998
@darklogic6998 4 года назад
@@user-JJJJJJJJJ Yes, all animals shared a single common ancestor. I see where you may be mistaken now sorry. As for my language analogy, Spanish "evolved" from Latin just like French. So one population of Latin speakers slowly had words changed to form a population of Spanish speakers ditto with the French-speaking population. A population of hominins slowly had genes changed (in the individuals of the populations) to form modern humans. So, no lizard gives birth to a non-lizard but slowly gradual change in a population of lizards may produce a similar-looking species to lizards that are not quite lizards. This change may continue to the point where they look almost nothing like their ancestor of lizards.

@Josh Noss DEBUNKED... Conclusion The Burdick track contains severe anatomic errors as well as abruptly truncated subsurface algal structures, indicating that it is a carving. The carver probably took a piece of limestone from a local outcrop, turned it upside down, and carved into the "bottom" of the rock. The knowledge that similar tracks were carved in Glen Rose, and lack of in situ documentation for the track, further undermine claims that the track is genuine. Creationists would do well to abandon the Burdick track. NEXT...

Josh Noss It can’t be true because evolution is a presupposition... all evidence that doesn’t match must be rejected... like when an evolutionist found soft tissue in a fossil that was supposedly millions of years old & they were attacked as either being sloppy and contaminating the fossil or straight up lying. They said there was no way soft tissue could still remain after millions of years. Then when others found similar results and the evidence became overwhelming, they were like “golly, well I guess soft tissue can last millions of years!” 🤦‍♂️

Hey Hank and the SciShow Crew, I'm an Accelerated Biology teacher at an upper middle class public high school in the Chicago suburbs. Last week was unreal. I had assigned this video for my classes to watch as a preview to our discussion of this topic. I received a complaint about the content and was asked by a parent if her son could complete alternate assignments to represent his own "worldview" of alternate "scientific theories" about the origin of life. Lest a parent complain to our Superintendent, my Department Chair and I offered apologies for this inappropriate material (specifically the first two minutes, where you justify science as a thing). Thankfully, we live in a state that has adopted NGSS standards and were unable to offer alternate assignments. Just WOW!

Leslie, isn't there something to be said in distinguishing facts from the interpretation of facts? We all can see that evolution is a very real and very amazing reality in the world we live. And Hank here did make a distinction between micro and macroevolution. We all see that there are SOOO many examples of microevolution. Yet the degree of the assumptions we are willing to accept in interpreting these examples of microevolution are much more nuanced based upon our entire worldview. For me it is very hard to simply believe that 7 billion people all evolved from one prokaryote. This is surely a Kierkegaard-like "leap of faith" compared to the epigenetics of lizards, thee strengthening of beaks or the breading of dogs.

I had a 95 in her class and she told me that she would drop me to a B if I said any more "ridiculous statements" like that. So I left the class, and got stopped by my principal in the halls who asked me why I didn't a hall pass. I told him how I disagreed with my teacher on evolution and how she threatened to lower my grade. My principal told me that he beloved in micro evolution and was sad "macrevolution" (which is a fairy take for grow ups) had to be taught in schools. Well the he advised me to make my own decision ad not be afraid of learning every atheist argument I could.

It's the people who take the middle ground, having their own view but also being open to other ideas, that are not the problems. And there ARE a lot of people like that.

Don't be hard on those religious people who find it hard to grasp Evolution as a concept. I have a Christian friend who is extremely open minded, but she is young and new to these ideas. When you have spent your entire life in churches and around other Christians who are endlessly backing up your beliefs, it's hard to even find the opportunity to find out any other information. After talking to her about Evolution she asks all the right questions and accepts fact as fact, but I can see on her face that it is conflicting with her own beliefs so it's hard to process this. If I were to yell angrily at her and call her stupid for not understanding, I would just be encouraging this processing of beliefs to cease - forcing her to return to her religious beliefs. Real discussion can lead more people to understanding this idea. Arguing and bickering will just make the divide wider. So if you really care about spreading knowledge then please consider your approach to the matter. There may be some religious people out there who are UNWILLING to accept the idea, but so are there many non-religious people who are stubborn and unwilling for change in their life, so we can't really blame them.

@brod2man
@brod2man 9 лет назад
TheAlphaShadows Well it's not a choice when you are involved in a religion. A person doesn't choose to become Christian over becoming Muslim. They start as an 'atheist' but then are taught or led to believe that a particular religion is RIGHT and the others are WRONG. Then they follow the word of the book that the religion belongs to. That's when interpretations of the book comes into it. This explains the different denominations of Christianity. But no Christian can ever choose to believe that Jesus didn't rise from the dead, or that he wasn't the Son of God. You have to believe these things or else you aren't a Christian. The whole religion is based on that. Possibly I interpreted your misunderstanding incorrectly.

+Martin Kunev Evolution is a flawed "Theory" Even Darwin admitted it had problems. If you look closely at biological systems a lot of them can not function if you take away a single component. Take for instance an eye ball, If you take away 1 single ingredient of all that it takes to make an eye ball function it will not work at all...so how did an eye ball evolve from a single cell creature if it can not work unless all parts are there. The probability of a single protein required in the building blocks of life life being created from random chance is like 1 to the 167th power (I am not sure of the exact number) for 1 single part. So the explanation for 100's of billions of years for evolution to take place in reality it would take 100's of times longer to have made 1 single protein to even start the process of life. Also of you look at just the biological systems of the human body it would seem each system is very complex and for all the complex systems to work together (skeletal, muscular, cardio vascular, nervous and so on) to make us work seems to me to have a specific purpose which suggest a design for then all to work together. If you have a design then you have to have a designer. This planet is also in the perfect location in the universe for all this to support life. Even with the astronomical probabilities of random chance you still have to have the environment to support such a possibility which in it self is an astronomical possibility.
@martinkunev9911
@martinkunev9911 8 лет назад
+No Name For some reason my response is missing, so I'll try to re-write it. When Darwin proposed the theory, a lot of questions were yet unanswered. Now we understand genetics and we've made lots of discoveries in peleontology, geology, biology, embryology, etc. With computers we can model evolution very successfully. "ingredients" don't just appear to form an eye, they evolve gradually. It's not true that an eye cannot work unless all parts are there (you can google aphakia). Here are some videos explaining eye evolution: watch?v=h5M8fXCyQ94 watch?v=fzERmg4PU3c Your concern about probability is addressed by the anthropic principle. All of the numbers you cite are totally made up and don't make any sense so there's nothing to be said about them. "seems to me" is not an argument. To some people it seems that women should be punished for being raped by stoning to death. The complexity of life is explained by genetic variation and natural selection. The imperfections of organisms refute any concept of purpose.

Johnny--One can KNOW there is a creator. Belief not needed. Why do dogs breeds look so different? In the genetic code of dogs there is a great amount of variation placed in the code. Same with all life forms. Yet the life form remains the same--there can be variation TO A DEGREE in SIZE (Example--height), SHAPE (example--Noses), COLOR (example, skin, hair, eyes etc). With the idea the wolf is the foundation code of dogs, humans SELECTED the TRAITS they wanted (you can see the different SIZES, SHAPES, AND colors of dogs). These TRAITS can be naturally selected also. One thing we KNOW. Dogs are Dogs. What if you found a fossil of a BULLDOG, COLLIE, and a GREAT DANE? You would think that they were different animals--AND you would use it as PROOF FOR EVOLUTION. Of course you would be 100% WRONG.

Except it isn't accurate science at all. Real science REQUIRES both OBSERVATION and EXPERIMENTATION.

All life forms remain as they are. Fish stay fish. Cats stay cats. Monkeys stay monkeys. Humans stay humans. Quite simple really.

If your here to make debate for the hell of arguing, please just buzz off, but if your here to discuss the aspects of evolution in a educational way, please stay. Again, they don't make these videos to create debate with the religious community or the intelligent design community, we are discussing a phenomenon that has been proven many times with concrete evidence. So, those who are just trying to defend your own beliefs, stop it, for we are not condemning them so you have no reason to lash out. Also, there is belief and then there is fact: belief is a perception of the universe, and a fact is what is actually true and fact does not change with belief and it does not have any relation to belief, (I am not attacking any specific religion or science, I am saying that belief should not be a factor here, there is only truth and concrete facts which we try to uncover). So please, so that we may just keep the comment section clean of these debates, which are pointless and emotionally driven, stop and learn for goodness sake. P.S, I am not responding to any comments that are filled with animosity or over bearing emotion, for I refuse to waste time arguing with people that probably do not watch these videos for educational benefit.

The lung fish has air-breathing lungs and gills, and fins that can swim but also walk in the marshy areas of ponds. It can breath in both water and land. So you could say the lung fish is half fish and half tetra-pod. (I'm not arguing, I am just answering your question. I personally don't know the answer to why evolution in humans "stopped" but I think it could be because we reached our prime, or perfect, form in the habitats that we currently live in. However, I think that we are still changing whether it physical or psychological.)

It is an ongoing, continuous process that CANNOT stop, even if the changes are so small as to be unnoticeable on all but the largest time-scales.

Kate the Great ....I can't tell if you're trolling, or if you're seriously that dense. You can connect the dots, and deduce the answer to those questions that you've posed, with just a very minor understanding of evolution. You don't even have to google them. Procreation - Ability: I'm not even sure if this is a real question. There couldn't have been reproduction, without the ability to do so in the first place. Regardless of the sex drive of a species. Bones or Muscles? - Uneducated question. Since we ALL evolved from cells, which evolved into fish, which led to us - There are a million different branches in which we could have evolved, our strain just so happened to have both bones, and muscle, which would indicate that they evolved at the same time. Eyes would've come first - Their evolution would've continued to progress due to necessity. That's why deep sea fish, have eyes, but not the ability to see, while predatory birds HAVE to have incredible vision, thus they do. Stomach lining, Gastric Fluid - Same as bones and muscles, they're co-dependent on one another, ergo - they would've evolved at the same time. Male or female - literally the same as your procreation question, cant have one without the other. I think you should research a little more, before you try to defend your position with objections like those.

I just don't understand your reasoning, yes, evolution is driven on necessity. Which would allow certain features and systems to evolve one at a time.

As a Christian, I believe in Micro evolution. It's all around us, and it is proof of an intelligent creator. That's not the issue between Creationists and Atheists. The issue is Macro evolution. (Ex. alligator to bird)

you just don't see that the pyramids will become sand again at some point, which means that if you pick up a single grain of sand, you can realize that the pyramids can come of it. That's all Macro evolution is; continued enough change COMBINED with geographic forces that eventually lead a population of one species to split into two, and boom, once they can't interbreed fully, each can be headed in a different direction. Or do you just think that Australia "looked like a good place" to drop off the Kangaroos after the flood along with all the other marsupials that evolved there? Seriously. You people just don't have critical thinking skills.

+pathetic mortal Thing is that evolution is a theory. There will always be a fact to support a theory. In the case of evolution, there are many facts that support that theory. But the reason that a theory is called a theory is because a theory itself is not a fact. Evolution is a guess, and there is so much more evidence against evolution than there is for it.

You can say that the debate is over but that is as silly as it is false. I encourage everyone who is genuinely interested in this knowledge to research the subject from all possible angles of vision and make a decision using the best of their intelligence. It takes a special person to be uninfluenced by the popular norm and consider the evidence as it is, without the need to be validated by someone else.

Evolution is not a debate, it's an observable fact. You need not have faith or believe in evolution much like you need not believe in gravity or heliocentrism. None of this is an attack on anyone's ideology, it is simply what we can deduce from the available evidence.

***** What an ignorant, inaccurate comment. Of course, with the PC propaganda presented on the Internet, I'm not surprised. If you so believe in following only factual information, can you please tell me where it says ANYTHING in the Bible about the Earth being the center of the Universe? Get your facts right. Ptolemy first postulated that theory, and Galileo was jailed by the Catholic Church, something that anyone with a molecule of medieval knowledge knows is a warped version of Christianity.

Wow, way to go copying and pasting a Google Search without thinking about it genius, how typical. Joshua 10:13 states that the sun stopped in the center of the sky. If you went outside and saw that the sun was neither rising nor falling, but it was in the sky? what would it be? Centered, am I wrong? You guys are so funny in your desperate attempts to over-analyze every Bible verse, yet accept any new scientific theory as unquestionably true.
@ThatGuy09890
@ThatGuy09890 10 лет назад
Wow, I'm sorry, but you have less of an attention span than I thought. Please explain to me how a verse saying that the sun was in the middle of the sky (from a human's pov) equals geocentrism (by the way, you first said heliocentrism, so way to commit the tu quoque fallacy.). You obviously aren't digging deep to this at all, and you have the same dogma that you are describing in your comment. If you're unwilling to change your beliefs just because you believe that you current ones are and always will be the only correct ones (which your 47 lines or so pretty much sums up) then I find it ironic how you say you are being honest to "yourself" when it's obvious that you simply rely on the Internet for philosophical advice.

+G Kelly Since both can be directly observed, they are comparable. However, the mechanism behind gravity isn't well understood. The mechanism behind evolution is. Thus I think evolution is a more solid theory. Wait, I spare you a comment by addressing the issue of 'directly observing'. Yes, we see evolution happening in organisms within years. Obviously we can't directly observe evolution over millions of years. However, neither can we observe gravity directly in most cases. We compute the orbits of asteroids by using the theory without actually seeing them most of the time. We detect orbits of planets in other solar systems without seeing them. Btw the orbits around other planets are actually fossilized since the information reaches us with the speed of light. We detect thousands of years old orbits. We don't even know the inner workings of gravity. We just know the maths. I tell you why you accept one theory and not the other: Religion.
@olivercasey3530
@olivercasey3530 8 лет назад
Considering the amount of religions out there and how many of those say that following a false religion is wrong (first commandment), is a big part of why I'm atheist. Though believing in evolution may be flawed in some ways it is still more observable and understandable (bacteria) than god making man from mud and women from man's rib and sacrificing the his son of a virgin to die for sins under the rules he created.

The question Clint posed is an interesting one: "why aren't there millions of transitional fossils?" This prompts the inquisitive mind to wonder a series of questions: what are transitional fossils, where should we expect to find them, how many should we expect to find, how many have we found, and what do they represent? The serious learner should be able find answers to these questions. Each time I've linked to resources here my comment has been removed. So this time I'm responding without them and will simply encourage people to pursue this on their own.

The relationship between religions and science is not paradox. Science accepts the existence of religions cuz those are precious social ideologies throughout the history, and vice versa, religions should also admit the facticity of science. I respect all religions and appreciate them. But wake up people, we are in 21st century, not 11st , 1st or whatever. It's kind of ridiculous to comment those not-believing-in-evolution words under a scientific curriculum video.

I don't understand how we talk about evolution as if it's something to "believe" in. This is something legitimate and literally right in front of us. No-one sits around and debates whether they "believe" that humans have hearts or whether trees grow? You can talk about "belief" of a religion/God because it's not something concrete or something you can provide literal evidence for. I'm not condemning religion or Gods, but it's something on a spiritual and personal scale rather than a realistic one. Religion and science can co-exist happily; but you can't reduce something so real to something imaginable.

@butterflypaint4332
@butterflypaint4332 6 лет назад
you are right in saying that evolution does have supporting evidence, it is important for even thoughs who belive in a creator do look at the evidence either way, but to say that it is more concrete than Creationism is a false statment. Both evolution and creationism have tremendious amounts of supporting evidence. But i will also go as far to say that both have a LOT of holes as well. Ive tried to take a good look at both the supporting evidence as well as the nonsuporting evidence for both, and at the end of the day what i can see is that no matter what ou choose to believe it is still going to require Faith for BOTH.
@timmbrockmann959

And why do Leopard and Jaguar looks so similar (while being on different continents). Plus, if all animals has different origins, why do even the strangest animal, or bird, or fish have the same kind of face structure that we have? I'm not an atheist btw.

I know Americans aren't the brightest bulbs in the box on a lot of topics but surely more than 40% believe in evolution!!! If they don't believe in evolution what do they believe in?? In the UK I would guess at about 98-99% of the population agree with evolution. (The other 1% being of not sound mind eg mentally disabled or something medically wrong with their mental capacity)
