How can a "thumbs up" sign help us remember five processes that impact evolution? The story of the Five Fingers of Evolution gives us a clever way of understanding change in gene pools over time.
Lesson by Paul Andersen, animation by Alan Foreman.
TLDR for students whose teachers are asking what the fingers represent:
Pinky: Chance can happen, resetting the gene pool
Ring: Non random mating can determine how often people with certain genes reproduce. If they’re unfavorable, the odds of them mating and passing on their genes are low
Middle: Mutation can add a new gene that changes up the frequency of all other genes
Index: Gene flow/movement can change the frequency of the gene pool if people with different genes come to a new area and other people leave, taking their genes with them.
Thumb: Adaptation will change genes to adapt to the surrounding environment

Can't find it.... must be.. EVOLUTION.
Oh wait... no... it's the M in the name... not on the actual finger- carry on.
Hi N.C, didn't think I would find you here
*I did the same thing* lol
Same XD
Same. Hard same.
It has been 3 years people say he is still searching
EVERYONE LOVES MR ANDERSON...EVEN THOSE WHO HAVEN'T MET HIM haha. His videos have been so helpful.

The theory of evolution is a dogma without any scientific evidence. It was introduced not for scientific reasons but for ideological reasons. There are no fossils that prove evolution. Millions of fossils prove no evolution. Living things did not appear by evolution but by the Cambrian explosion. And traces have been found that prove that people from the times when Darwinists claimed that people were half animals were fully human. There was no such thing as evolution. And countless studies in laboratories have failed to turn up any examples of beneficial mutations. Almighty Allah created living things not by evolution but by the Cambrian explosion. The functions of all organs, which Darwinists call obsolete organs in living things, have been revealed. In other words, there is no such thing as an expired organ in humans or other living things.

Thank you for this nice and concise recap of the five general mechanisms of evolution!

Science is a whole different 'breed' of writing. Most people cannot grasp the dense, thought-driven concepts in long, drawn out science papers because when you are writing scientific research papers you are basically cramming all of your information into the best words you possibly can and you are writing it specifically towards people with a bachelors/masters degree. Its a lot rougher to get through than normal papers and is much more specific, which denotes it the term "scientific literacy."
When it’s the night before your AP exam and your studying
Great and clear explanation. Thumbs up!
One of the best informational videos, it really helped me understand (i'm a very visual person)!
Thank you for making it!!

187 people saw this video literally prove evolution as an unavoidable outcome of existence and still disliked it. Seriously stubborn.
Evolution is such a central concept in biology. How can you say you like biology, the study of life, if you don't understand the concept of evolution, the process of how life has come to be what it is now.
Anyone else here for biology class
Tony Klaer yessir
Biology class ?
Ted Ed is really the best CZcams channel according to me.
Uranium-lead dating contains most of the problematic features of other dating forms.
1) Lead 206 can be formed by processes other than decay (Neutron cross section)
2) Based on the assumption that no event or condition in the past has occured that could have altered decay rates (extremely unlikely)
3) Uranium 238 is water soluable, so water can carry this element, depleting or enhancing estimated dates
4) Error Margin for such dating can span hundreds of millions of years
This guys from TED are great, they defenitely should spread their videos throughout the schools all over the world. I just think they should make a video on thermodynamics, its 4 laws formulas still don't drill well through my head. T_T.
I can think of another process that uses 5 fingers (and sometimes the rest of the palm) and does not result in evolution

Keep in mind this is a 5-minute high-level over view ostensibly designed for children and people not previously familiar (or perhaps even interested) in the subject matter. There are a lot of intricacies and interdependencies that have to be cut or glossed over. Mutation, as a process, is one of the mechanisms that drives evolution, even if specific, individual mutations must continue to be selected for and propagated to take hold in the population.
I wholly stand by my statement. Evolution is not dependent on mutation. Evolution is a process in which organisms change over time. As the video clearly shows this is done in a few different ways. Mutations are one of them. Mutations aren't solely responsible for evolution, Genetic Drift and population mechanics, as well as biased mating or abiotic factors all go into the process of evolution, Remove mutations from the list and you still have a working system.
Shuffle me, baby.
lmao thx i rlly needed that laugh
Bro that was amazing lmfao
Man, our Biology teacher taught us this method
Ohh. How much I love Paul Andersen
As for the math, I'll address the water levels first.
In order to understand this concept, you must remember that the earth's topology was not always what it is right now. Theories such as plate tectonics and continental drift all show that the earths topology has drastically changed. Did you also know that if the entire surface of the earth (including the ocean floor) was leveled, water would cover the earth by 1.7 miles?
Hm. I didn't know red hair was an incomplete dominant gene - I wish my teachers covered genetic transference more deeply than "they're either dominant or recessive."
It is too difficult of a concept for highschool right now. I learned all these things and many more studying molecular genetics and biotechnology at uni and i doubt i would be prepared for the full picture back in highschool.

I'm definitely addicted to these videos.
Now I will refer back to the story of our individual.
Our individual is in competition with members of his species. The long lasting flood was a random event, the competitors are random in that they are the individuals within his species he is competing with. However the non random result is that our individual survives due to his webbed feet, a trait which his competitors don't have. Hence we have a non random result from a seemingly random assortment of factors. It's not math, It's Biology.

Lol
where is the "m" on the middle finger i can't see it i am triggered
Fresh Fishyy mmmm. In Middle...MMMMiddle...oh! Right there!
BTW: It was some 19th century theologian who 'calculated' the origin of existence using all the 'begats' in the Old Testament. He wasn't accounting for 'creative license' and the inaccuracy inherent in the unrecorded histories of our ancestors. See 'Inherit the Wind' the wonderful story of the Scopes Monkey Trial starring Spencer Tracy.
It is at this point which we realize that the differences which built up between the two populations over the many years has finally culminated in the emergence of a new species which is different enough to hold its own place in the world. Now it contends with interspecies disputes over resources or space, eventually one would gain the edge over the other, causing extinction for one. All this time each individual still competes with others in the same species in a never ending genetic arms race.
Thanks to this video, I failed my biology test :)
I don't think it's right to say all animals share a common ancestor. Is it not possible that life started in more than one place?
+jonas ferencz I think the genetic pattern of the species contradicts that notion.
I don't mean the animals we see today. I'm not saying monkeys are not related to whales. I was more talking about the first organisms, the ones that combined to form more complicated cells.
jonas ferencz
I'm no expert here, but a quick search seems to indicate that multiple origins is a known hypothesis, but that it's mostly refuted. Not sure if these answer your question 100%, but they're worth a read: whyevolutionistrue.wordpress.com/2010/05/15/modern-life-had-a-single-origin/ news.nationalgeographic.com/news/2010/05/100513-science-evolution-darwin-single-ancestor/
+jonas ferencz Our genes are too similar for that to be possible I believe

When Brazeau and Ahlberg measured this bone in Panderichthys, they discovered it was much shorter than in earlier fish. It also was not directly connected to the jaw joint. It appeared to be in the middle of moving to a different part of the skull where it would become an ear bone -- a migration that would take tens of millions of years to complete.

Who else is here because of "biology class"
Bozeman Science!
towards the end he says that none of them lead to adaptation but doesn't the first example, where a small number survives an epidemic, mean that the entire population is now immune, or adapted.
+anywherein12seconds
That's natural selection. Those with immunity survive and pass on their immunity to their offspring. I think he was more referring to an event that could cause a population bottleneck, reducing population size and therefore genetic variation in the population.
With our world's problems we solve
As earth spins around all we revolve
Pray humanity's sins we do absolve
Involve yourself before we dissolve
To be part of the solution we evolve
MR. ANDERSON!!!!!
Evolution is a CHOICE. God said Adam and Eve, not Adam and Harambe
Asi Mailau Harambe created us all in his image through Harambelution. Wake Up people.
Evolution is very real. But that doesn't mean god doesn't exist or make god's teachings invalid. I say this as a Christian who believes in evolution
It was a joke, are you shitting me
I literally mention Harambe, it's a fucking joke.
Asi Lou Mailau it was a little hard to tell LOL! >~<
I thought you were joking but then I thought maybe not
I am not trying to control other people's opinions, and your right, i DO have an unshakable opinion because the way I see it, the only reason people get worked up over opinion contrary to their own is because they know they might be wrong, therefore i am unshakable because i believe fully in what i think is true, unless overwhelming evidence says otherwise...
This really helped to study for my evolution test tomorrow this is one of the essay questions on there so this really helped i liked it

Quick Fix, the range is 100,000 or so years (my mistake). Also you can only calibrate the dating clock within written history as numerous unrecorded changes can alter atmospheric c12 to c14 ratios. I will list them in another comment.
Scientists have come across these issues, however due to there being few other options other than radiometric dating they accept the current system with its flaws and try to filter out "bad dates" based on their preconceived notions about the earth's origins.
The English word theory was derived from a technical term in philosophy in Ancient Greek. The word theoria, θεωρία, meant "a looking at, viewing, beholding", and referring to contemplation or speculation, as opposed to action.[1] Theory is especially often contrasted to "practice" (from Greek praxis, πρᾶξις) a Greek term for "doing", which is opposed to theory because theory involved no doing apart from itself.
'jean' pool XD
christians only have one finger, its the middle finger and its "god"
One of my favorite hobbies is searching for the comments of those religious nutcases. It's funny that other videos like this do not contain anti-scientific comments but as soon as evolution or the scientific time scale gets mentioned, all the religious lunatics rush to the comment section to advertise their ignorance.
@@late8641it has also now become my favourite hooby, thank you!
I loved the presentation. It was clear and adorable!
Thanks. It's easy to understand
Just depends how you define the word. As the speaker says, microevolution means shifting the existing genes around, like is done in breeding or domestication. This process alone cannot lead to macroevolution, and neither can natural selection alone.
I have 6 fingers so how can I restore my fingers?
You cannot make a new theory out of thin air. To come to a scientific theory you first have to go through the process of the Scientific Method (Question->Hypothesis->Prediction->Test->Analyse). After you have gathered all the tests, evidence, answered the scientific questions, and made a conclusion then you have come to a scientific theory.
Nothing can be measured with 100% accuracy. All the variables of a given system cannot be known at one time.
People watching this with 6 fingers: 👁️👄👁️
Lol
Most people don't know that micro evolution doesn't mean a small change and macro evolution is not a big change, macro just means two animals cant breed (or their offspring is sterile) and micro means that animals can still breed. ie Chihuahuas and Dalmatians can still breed (In theory) although their difference appearance is great.
What he says is "non-random" mating. Selective breeding in other words. When mates don't mate randomly, but select traits they want in a mate, they affect the frequency of the alleles for those traits, which is evolution and over enough time could affect the frequency to the degree that speciation occurs. Random mating would result in a sort of genetic equilibrium. NON-random mating does not.
Just because the fight is with random fighters it doesn't mean that there is bound to be a random outcome, If I were to pick two random people off the streets and had them fight to the death one would win. And the one that survives wouldn't have won off of chance. Randomness may have chosen the fighters, but it does not define the winner of the fight.
At the end I high fived myself.
Forever Alone.
"... I fully agree with your comments on the lack of direct illustration of evolutionary transitions in my book. If I knew of any, fossil or living, I would certainly have included them. You suggest that an artist should be used to visualize such transformations, but where would he get the information from? I could not, honestly, provide it, and if I were to leave it to artistic license, would that not mislead the reader?"
1) Mutation is the only one of the 5 named processes that can create new genotypes
2) Macroevolution can only happen if new genotypes are created
3) In order for a mutation to enter the gene pool, it must represent a functional gene that is better suited for survival so it will be preferred by natural selection
4) The conditions in #3 have never been observed, and no theoretical examples have even been put forth
5) Therefore, Macroevolution has never been observed, and has no theoretical basis
To add to what I said earlier. The reasons why we have distinct races today is the same reason why we have pure dog breeds. By frequent inbreeding of similar types of people, genetic variation begin to diminish causing a very homogenious population. Due to our nature, people who are alike tend to band together and often alienate those who are different, this accelerates the process.
Mutation leads to a wide variation base from which the 'fittest' survive to reproduce. Nature doesn't *know* what's required for survival, but the organisms gifted with the best random ability to survive and reproduce, do so.
Great video. I show it every year.
thats actually his point, what he is saying is that it is impossible for the earth to be only 7000 years old. If you look at the earlier comments you see where BlackMC06 said that the earth is 7000 years old, and Bryan Peebles debunks that idea with his argument.
the point is that if you have a lot of pigment in your skin, the light can't reach the protein synthesizers even through more light is absorbed
Speciation occurs when a population can no longer mate with another population of the same species. Another thing is that the offspring cannot be sterile, this is why horses and donkeys aren't considered the same species, mules are sterile. Look into Ring species, that provides answers to many other questions you have on speciation.
Before you read this sentence and think it out of context read the full original article or read The National Center for Science Education (NCSE)'s "What Did Karl Popper Really Say About Evolution?"
It is quite interesting.
The support you gave me is a video that cannot be addressed in only 250 words so I have sent you a mail addressing the main 7 points of the video you have provided.
We lost these abilities because they were not needed,but what drives evolution to head a certain direction?Why did a dog get teeth and a bird get wings and how does nature know what is necessary for survival?This question is very complicated to me.
Love when the dude on the bike evolves ear instead of legs :D
its called dominant and submissive genes, i cant go into detail at the moment due to time restraints but youd do well to research it on your own.
ill sum it up as "just because they did not carry on the red hair gene from the ancestors does not mean it was gone."
I like how the narrator didn't have a bias against evolution
If you don't understand it at this point, there's little chance you ever will.
Nature doesn't "know", it's not an entity. Things unfit to survive die off, it's that simple. Those able to adapt to their environment prosper and spread. The mutations and changes happen at random, and those that get the beneficial ones take the next step forward in evolution.
1. Define Evolution
2. Draw a picture of a hand and label the 5 Fingers of Evolution
3. Detail each of these labels in full sentences.
4. Describe how red hair is an advantage for some but not for others.
5. Done: Hand in your HW in CLASS and not electronically
What an awesome video!
1) We are related to every other animal, however distant they may be, but since you seem to be speaking about similar species and so does the article, Neanderthals and Denosivians also had 23 chromosomes.
2) The fusion of Chromosome 2 is a neutral mutation, so it's not a significant mutation, so it is possible it can become the genetic norm in a population.
3) About 70,000 years ago, human population hit about 1,000 so it is highly likely it became the genetic norm.
Many mutations don't yield a better outcome, but occasionally it does. Imagine a small organism without eyes. A small change in only a few cells to make them sensitive to light can be a huge advantage, so that mutation has a chance of sticking around in the gene pool. However, if a mutation happens that would, say, make it unable to breathe, it would just die and clear the bad mutation from the gene pool. It's random chance but it builds up from what's there but can be better, step by step.

Millions of fossils prove no evolution. Living things did not appear by evolution but by the Cambrian explosion.

I agree with what you're saying, but it's not really what I was saying. For instance, when scientists say an animal without an eye suddenly gets an eye out of pure random mutation, that's just absurd. And not only is the eye perfectly made, but it fits perfectly inside the animals skull and completely connects to the brain allowing for each generation to have amazing vision due to the fact that a ton of the brain's memory is taken up by eye sight. Now how does that make sense?
i don't expect every jumble to produce 1 correct order, sometimes it may be 1, somtimes 3. most of the time none. but each jumble has a chance of producing 1 right, and everytime that happens you keep it. THATS NATURAL SELECTION. the keeping of 1 correct ball is natural selection, its like the generation surviving because that 1 correct number gives it a better chance of surviving. i did this with a deck of cards just now and got 1-10 in only 25 generations.

These videos are extremely professional.
Through the expression of certain genes found within the genome, these genes are selected through various means, Some are through simple dominant/ recessive interactions between marker strands of DNA which signal various proteins found within the nucleus to begin transcription, Transcription reverts DNA to RNA and eventually into Proteins, thee proteins then form structures which provide the phenotype which we see in one another, This is the emerging field of Proteomics.
