Hank brings you the facts, as they are understood by scientists today, about the evolution of humans from our humble primate ancestors. On the way to becoming Homo sapiens, game-changing evolutionary breakthroughs led to the development of many hominin species, now all extinct. Hank will introduce us to these species & the breakthroughs responsible for their development, and help us understand the awesome ways in which they led to us.

Shammo Hamid >> a scientific theory isn't a guess. It's a collection of facts and guidelines to understand those facts. It isn't a guess like every mainstreamer think it is. A scientific guess is called a Hypothesis. It's something which is mathematically possible, but is yet to be proven in reality. Cause here's the thing. Math is also "just" a theory. Have a nice day

*REPENT!!! Repent and accept the one true god! TALOS!* Talos the mighty! Talos the unerring! Talos the unassailable! To you we give praise! We are but maggots, writhing in the filth of our own corruption! While you have ascended from the dung of mortality, and now walk among the stars! But you were once man! Aye! And as man, you said, "Let me show you the power of Talos Stormcrown, born of the North, where my breath is long winter. I breathe now, in royalty, and reshape this land which is mine. I do this for you, Red Legions, for I love you." Aye, love. Love! Even as man, great Talos cherished us. For he saw in us, in each of us, the future of Skyrim! The future of Tamriel! And there it is, friends! The ugly truth! We are the children of man! Talos is the true god of man! Ascended from flesh, to rule the realm of spirit! The very idea is inconceivable to our Elven overlords! Sharing the heavens with us? With man? Ha! They can barely tolerate our presence on earth! Today, they take away your faith. But what of tomorrow? Do the elves take your homes? Your businesses? Your children? Your very lives? And what does the Empire do? Nothing! Nay, worse than nothing! The Imperial machine enforces the will of the Thalmor! Against its own people! So rise up! Rise up, children of the Empire! Rise up, Stormcloaks! Embrace the word of mighty Talos, he who is both man and Divine! For we are the children of man! And we shall inherit both the heavens and the earth! And we, not the Elves or their toadies, will rule Skyrim! Forever! Terrible and powerful Talos! We, your unworthy servants, give praise! For only through your grace and benevolence may we truly reach enlightenment! And deserve our praise you do, for we are one! Ere you ascended and the Eight became Nine, you walked among us, great Talos, not as god, but as man! Trust in me, RU-vid! Trust in the words of Plato! For I am the chosen of Talos! I alone have been anointed by the Ninth to spread his holy word!

I kind of wish I had gone to a religious school for my high school education. It would have been much easier. My bio class would have been only 2 minutes long, my earth science class, about 1 min long and chemistry about the same length too. "Hello, students, I am your science teacher and the administration, school board and clergy have made sure that you get the best science education on the planet. Please turn to page one in your bible. If you have any questions, the answer is 'God did it'. Test tomorrow. After your test, we will sing some hymns and hold our hands up high while we worship sky daddy, the guy who 'did it'." But, my parents chose a public school for me to attend so that I could get a proper education. Thanks Mom and Dad.

@nateboltz8599 9 лет назад

saxmanchiro I'm a Athiest that goes to a private Christian school. I choose to go because of the small classroom size, personalized education and lack of harmful standardized testing. There are a lot more factors that go into choosing where you get you're education then what meets the eye. I choose to educate myself and do my own research because a lot of the public school curriculum is skewed also.

@saxmanchiro 9 лет назад

Nate Boltz "public school curriculum is skewed.." Not in sciences. As to the other things you listed re private schools, I understand since I attended one for high school. Just make sure the school is not pushing their particular religious views re science and you are good to go.

@amiblackwelder 8 лет назад

I think a few of you need to understand the difference between fact, theory, law, and hypothesis. A fact is an observation. Like there is water dropping from the sky. A Theory tells us WHAT and WHY. A Law tells us HOW. Facts are just observations. GRAVITY is a LAW and a THEORY. Not one or the other. The Law part tells us HOW in MATHs and the Theory part tells us WHAT and WHY. Theories and Laws are supported by EVIDENCE, EXPERIMENTS, MATHS, and PREDICATIONS. A Hypothesis is a possibility, an idea. It takes many of the above evidences, experiments, and maths and predictions that come true to solidify something as a theory and as a law. There are stronger theories and weaker theories. However evolution IS a stronger theory, having been tested more than every other theory. Some of our strongest theories are: Evolution, Big Bang, Quantum Mechanics, and Gravity. Evolution IS adaption. It is not one or the other. Being able to see how this adaption happens on smaller scales and then larger scales is truly a beautiful thing. Many of you have a wall up that does not want to let evolution in. For some of you this is because of pride. For others this is because you truly are not educated on the issue and for others it is because of your religious beliefs. I recommend researching the issue on the internet about the facts, evidence, experiments, maths, and predictions all supporting evolution. For example. The LAW of NATURAL SELECTION is a LAW supporting the Theory of Evolution. So is...The LAW of Fossil Succession, DNA, the age of the universe, the age of the Earth, and so much more. I highly recommend a class in or an internet search on HOW TO READ GENESIS. Most of you are not taught how to properly read the Bible and this is one of the gravest mistakes modern churches have done to the public. If you have a question, please email me. I'm happy to help. A book of mine of this very topic is called THE ANCIENT GENESIS. I'm more then willing to discuss the religious viewpoint on evolution.

Zach Schmidt What does that have to do with biological evolution or the belief "man came from dirt"?

Lots of people think that before Darwin everyone a creationist or something. Not at all true. Linnaeus classified all living things accouring to their relationship with others 70 years before Darwin was born because hundreds of years before him naturalists assumed all living things were decneded from a common ancestor. What Darwin did was describe the method in which one species changes to another. Long, long before him everyone knew that they did.

@othertestchannelbeta 10 лет назад

Notice this video says facts about evolution? That's because there are scientific facts of evolution. A scientific theory explains facts, such as mutation which causes variation and natural selection which picks successful mutations. The majority of people who believe in God accept evolution, because it describes facts. The Theory explains the facts.

@GoodScienceForYou 10 лет назад

There are NO facts showing human evolution, for example. All the evidence we actually have only shows we are rapidly heading for extinction.

@Kban13 10 лет назад

GoodScienceForYou Actually, there are plenty. I'm sorry you're too stupid to understand them, but that's no reason to spout lies.

@othertestchannelbeta 10 лет назад

Whenever I speak to religious fundamentalists, I try to met them halfway by suggesting they read the Language of God by Francis Collins, the scientists who mapped the human genome and became an Evangelical Christian. If they read his book, at least they'll have a grasp pf the facts of evolution, mutation and natural selection. Detrimental mutations tend to result in miscarriages.

@sophiedoon7950 10 лет назад

GoodScienceForYou Of course there are no ‘facts’, Science deals with evidence. Surely one of the smartest people alive, that’s you, should know the only people who can outright deal with facts, are Mathematicians, not Biologists. However, there is a mountain of evidence, for example; a continuous line of hominid fossils that becomes more and more human like, the earlier the fossil is.

@GoodScienceForYou 10 лет назад

Sophie Doon What about the modern Homo Hominid found in Australia? When it was first discovered they thought they found the missing link. "1000" cc brain capacity depressed skull and all these dumb ass beliefs were triggered. evolutionforum.info/yabbfiles/Attachments/pintubiangl.jpg evolutionforum.info/cgi-bin/yabb2/YaBB.pl?num=1335717542 It turns out to be less than 100 years old and and extinct tribe from Australia. IT IS JUST LIKE ALL THE EXTINCT HOMINIDS THAT DEGRADED AND WENT EXTINCT FROM MUTATIONS. It amazes me how silly Evodelusionism is. If you have no DNA and you dig up an extinct creature with absolutely no trail of existence after it went extinct, then it is not evidence of any form of evolution. It fits with all the other DNA evidence we have today on modern humans. There is only one path of "evolution" and that is we were put here and as time goes on we are destroying our own genetic structures from ignorance. If you are weak and needy, you will want the fantasy. If you are a seeker of the Truth, then you only want absolutely irrefutable physical evidence before making any conclusions. This type of evidence is all around you. Evodelusionists ignore it. That is why it is called living in the darkness of "ignor----ance". For over 40 years, with the first DNA testing, we have never found any form of evolution. We have well over 1,000,000 DNA studies with upwards of 100,000 deleterious mutations causing us to be weak, need medical and technology to survive. Humans have NEVER improved in any way shape or form. We are more tribal, separatist, hateful, and make up all sorts of new religions to keep us hating each other. Evodelusionism is the worst religion to ever plague humanity. evolutionsciencenow.blogspot.com/2013_06_01_archive.html

@Legolad 10 лет назад

Phrasing matters, SciShow. Especially in topics like evolution. Statements like the one at 7:51 are not helping. Don't say "The only solution was for babies to be born before their brains were fully formed." This implies that our genes are making the decision to give birth earlier as a solution to the large head problem. Not only isn't this true, it also confuses people who are already at a disadvantage in understanding how evolution works. It sounds like a small thing, but I have made this clarification many times when discussing this topic and you might be surprised at how often it becomes the "lightbulb moment" for people who were unsure about evolution. You might think it's a harmless little verbal shortcut that makes it easier to explain evolution. Trouble is, it ascribes nonexistent motivation (and functionality) to our genes (a strange form of anthropomorphism) and is so obviously logically problematic that even young children spot it. Worse, it creates seeds of doubt in their minds, leaving them susceptible to the non-science of the Creationist crowd. Instead, say "That meant babies who were born before their brains were fully formed were less likely to die or kill their mothers during childbirth. As more early-birthing mothers survived, they passed that early-birthing trait onto their children until early-birthing women became the norm." Every time we explain science poorly, we open the door to non-science.

plus many animals are born before their brains are fully developed and the human genome project showed all humans are missing a gene that shows up in most primates that give them a strong muscle that come over the top of their heads and connect to the jaw giving them more bite force but also forces the skull to close fully and earlier in life than our own. Here is my thing if food lead to increase brain size along with being bipedal then manny of our domestic animals who are fed better than in the wild would be showing the same signs especially rabbit and rats as we have been feeding and breeding them along with dog (who are proven to be LESS intelligent than wolves) WOULD ALL show these signs of change even horses would have show signs of this change and there isn't much change at all even with our assistance to say food caused the mutations that started in our brain to lead us to now is stupid I mean I have read about 15 papers on the subject each being like a book in itself and there is no sign that this is even close to accurate. it is just a theory a guess that has no standing but COULD be so but very unlikely it is more likely that aliens gave us our mutations I mean come on just look at the thousands of years of evolution this would have happened to at least one other animal or at least started in another animal . It is more likely that our line started to become more specialized in its DNA and got rid of excess DNA after all many things have more DNA than we do so there is more room to hide traits but more ability to adapt each generation. people are good at creating but without our tools we would be in very select places of the world and would die out quickly do to world changes.

@ThePenguin369 5 лет назад

Nicky s there's already been a sci show episode with a possible new discovery of a multiplication of a gene which could be the reason we have higher intelligence, although protein would help fuel a large brain, when you think of all the animals who eat just meat it does not create a pattern of higher intelligence vs those who don't.

I'm a Christian and I totally believe evolution is the way all things change in respose to themselves and the environment. Lets be honest, the Bible is a great guidebook to how to find personal enlightenment but what worked 2000 years ago ain't gonna fly today when there are facts. Remember, religion is man made. God is what you see when you look out into the universe.

I guess you can say I believe in intelligent design. I believe that whatever religion one follows is a personal decision and once it becomes forced down anothers' throat, it becomes facism. I was just sharing a thought really with my comment. I really wanna end any topics on religion because like politics, it's all a matter of opinion and anything one way or another will always cause heated debate. It's just good to know we're all here, really.

How can you disprove something that in its very nature is unproveable? Religion is based on faith which is believing without seeing, so there is no proof of it existing and so no proof that it does not.

@jamesjameson2408 9 лет назад

Cloud Seeker Please explain how this is rock solid evidence against God? Also, please do explain exactly how evolution works on a DNA level. How do beneficial random mutations occur in order to add (or scramble) the DNA to create a completely new kind of animal or plant? Please don't add the magic ingredient of millions of years as an answer for evolution to happen. I've never heard a decent answer to this question and I'm just curious of how you think it happens? Everything that is known about DNA changing to create a new kind of animal proves it is mathematically impossible for this to occur.

@dantewynter9211 9 лет назад

James Jameson hes joking... please stop.. denying science is only going to look bad on other theists. besides, evolution is not purely for atheists. a majority of christians and other theists believe in it as well.

@Cloud_Seeker 9 лет назад

James Jameson What the fuck are you talking about? When have I talked about evolution? Also as Dante Wynter say, evolution isn't purely something for atheists. All big religions have accepted evolution apart from the backwater denominations of the religion. Evolution denial is pretty much only something you see in the US among fundamentalists and in undeveloped countries where knowledge is overall hard to get.
