1:23 So it turns out that Darwin didn't actually take much interest in the Galápagos finches at first, so much so that he took little care in labelling where each of his specimens had come from. Moreover, it was John Gould who pointed out the similarities between the birds first who pointed this out to Darwin. Many years later Peter Lowe coined the term "Darwin's finches" essentially popularising this anachronistic concept. See this link for more details geneticsunzipped.com/transcripts/2020/1/2/darwins-finches (thanks to Alex Palazzo for hunting down that source!)
8:04 As Alex also pointed out to me, the appearance of mutations here could be misinterpreted quite easily to be "coming from" the environmental stimulus. I did not intend for this. What I really meant was that random mutations occur (or have already occurred) and are simply more likely to be selected under the new environmental stimulus. As I mentioned in the video, this selection would be unlikely to occur without the stimulus, so it is still of paramount importance, but it is certainly not causing the appearance of a new mutation.

All previous scientists represent the state of their art. A building block for the next generation to start and grow our understanding with greater accuracy. Mendle demonstrated inheritance. Newton gave us a fundamental set of properties that are repeatable under theoretical conditions. As we evolve we grow.
According to acclaimed British biologist Denis Nobel Dawkins-flavored neo- Darwinism is just plain wrong.

The bacterial Flagellar Motor is a biological machine. It can be observed. Your observation won't be misleading compared to the analogous animation in this video.
faith members speak two tongues and use various subtle signs, with hands or body and speak English and a ancient European tongue, Cops do not even notice the language, the sign was he is a undercover cop who thinks where criminals. response we have nothing to hide, another he is not faith, his face is wrong. Another let's play along. Another he sounds funny. Another don't speak the tongue, The faith has no history of criminal behavior, but members have killed ex-cons in the past. The faith is considered a pro-abortion right-wing group with a history of siding with the moderate republicans on the issue of abortion. People have claimed before that faith look like clones, similar faces and paler shades of hair. Faith favorite sign might be, I am lying. while speaking a lie. The faith has a history of secret societies. One of the English versions was called the SSS, secret society of scholars. A couple of the European churches used to really hate them and where more likely to kill their own supporters then faith members. The faith even used to use the Christian bible as a code. making it possible to pass off information right in front of priests without their knowledge. Nobody knows its true age, anyplace from 200 -400 years. The faith built a faith colony in the USA and their is always the possibility that is a new one based off of the old one that was barely officially known in Europe. A old attempt to keep it from spreading. Its more than possible that the faith helped weaken the church in Europe. having members who were nobles, priests and commoners. The faith is less secretive than it was in the past and has billions of dollars. The faith has a good size town made up of nothing but faith members. No Irish, French, chinses, black, lutinoes or blondes and blonde are considered to be allies in some of the nearby towns. The faith leftovers sometimes absorb into blond groups and become blonde when not being able to find a more similar browned haired group and normally requires leaving the faith or becoming semi-faith. Blondes look more alien to them a result of the blond hair. A strong preference over lutinoes, blacks, black haired peoples and Asian. faith almost always produce blonde children with blondes, that causes some odd behavior in blondes in those regions, Faith DNA seem to cause alien people to look even more alien and revolting. A rise in assault of black people by blondes, faith rarely commit such acts. Image a hideous alien monster covered with slim approaching you from a distant planet and you will understand how faith feel, with faith its combine with discipline and self-control. Faith preaches moderation in hate, disliking hate disorders and lack of control and anything that may have a negative impact on their instincts. Faith seems very logical and polite but behind all that reason and logic lies their instincts. Faith members are not very greedy and normally have to be encouraged to be greedier. Both a strength and a weakness, less greedy people are normally more difficult to control with the downside is something else has to be used for motivation. Faith members are not known for jealous behavior, Jealousy is a large threat for jealous people will attempt to murder and maim those that make them jealous, good looks, smarts, wisdom, wealth, better bodies. Who know what comes first the jealousy or the hate. Perhaps such people could never be safely absorbed into the secret societies that seem to make up their gene pool. Such a thing would make the members more disloyal and shatter what's hold them together and would have gotten them dead in some time periods. history reshaped genetics. Faith where in for centuries what some may call a controlled gene pool. Perhaps the faith will have to in some periods move back into a more secret society a 2nd time. Secret societies are normally a result of oppression, preserving something, power or crime. In the old times it included preserving, writing, books, artifacts, weapons, history, cups, treasure, old stories, new and old Christian testaments, pagan Knowledge and the old bloodlines. faith still has in their possession all but forgotten and banned Christian testaments. Some of their artifacts, writing are believed to of been smuggled into the USA along with gold and silver. The vast majority of secret societies live and die and never grow beyond a hundred people. Faith is still very very organized and structured and number in the thousands, nobody really knows their true numbers, it could be a couple million or more. The faith may not preach the bible but own and use Christian churches, libraries, own large amounts of data bases connected to the internet, move data around, Own companies, small, large businesses, factories, maybe even a profit generating corporation or two, the faith has some nonprofit organizations, farms of various sizes. Faith small time labels are sometimes sold in their stores. The faith has their own local cultures. faith birth rate seems to be high compared to other pale groups. low divorce rates. A almost disrespect for politics and political ideologies. Faith has this tendency of looking at Politian's as corrupt, immoral threats with the hope that a decent person will one day gain power. The faith believe the USA has never had a half-way decent president since Thomas Jefferson. A faith member once tried to get him reelected in the year 2000. Faith humor can be Easly or hard to take, someone once called a faith member a retard, he acted retarded around that man for almost a decade. nobody else but that one man. The man complained a few times, but it fell on deaf ears, and he even got mad a few times and started to yell something like you are not a retard stop doing this to me. He ended up with a decent amount of people acting retarded to him. faith experiments can go on for days, decades even be handed down to the next generation. The faith still has a war dog experiment ongoing that is over a hundred years old. The faith might have the largest breed of that dog type. Selective breeding, genetic could speed up the small under funded project of trying to make the dog breed bigger and smarter. No new genes can be used in the project only removed.
So what I got out of this is that the protein should be thought of less as single-purpose circuitry components, But more complex multipurpose machines in their own individual right. (Like an excavator or a skid steer that can do many tasks with its default tool or switch out tools, Except all of the tools are built into the thing like a Swiss Army knife.)
This seems like a cheap gotcha. Machine parts can change shapes (compliant mechanisms for example). Just because a protein doesnt behave like a bike chain doesn't mean it doesnt have machine-like properties. The key difference is not whether proteins jiggle but that machines are designed with purpose whereas cellular mechanisms arise out of self organisation and evolution.
If the basic wasn't teached, then there was no real teaching. There is only one gender in humans.
We shouldn’t compare living cels to machines more accurate comparison would be a living Python (or some highly object oriented programming language with high level of abstraction) code with threads and multitasking enabled where all functions could actually pass stuff to each others 🤔 God said to himself after a weekend - “where did I finish last?” -“ah was stomach cells code ok let’s code liver cells” 🙂
From a kid perspective - marble run sounds WAY more fun and interesting than pinche punnett squares
So, it’s misleading because the parts are more like jello than legos?? I think the nano machine is a GREAT analogy, as does the world of science.. it’s the scientific community’s lingo we are adopting here.. they came up with it.. your video title is misleading and your attempted definition at what a “machine” is, is misleading.. watch terminator two.. it’s the Liquid Metal guy “not” a machine? Because he jiggles and changes his shape??

Newtonian concept of a clockwork universe was the comfort zone of physicists until Einstein and later, Niels Bohr and Max Planck came along. This is what SubAnima has done to Veritasium with this video. Veritasium has had his run and it was a good run. Now his videos are mostly clickbait than real science.
But if they are not blueprints, why are twin siblidings mostly identical even if they are separated at birth and have a different upbringing?
Michael Levin.
Seems to me that just because *some* proteins multitask it doesn't mean that in any given context a protein doesn't in fact have a specific job to do and operates as a discrete part of a process for as long as required. For that time no matter how transitory the proteins are analogous to fixed parts in a machine taking inputs and producing outputs.
SOOOOO COOOOOOOOOOOOOOOOOOLLLLLL SOOOOOOOOOOOOOOOO COOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL oh my gosh I love biology so much thank you for helping me understand why I love it so much. literally my protiens are jello. how do they work so much. literally they are working billions of times every fraction of a second in every part of my body and the world.

Has there been any revision done to the way we teach math?
literally nothing in our natural world can be explained in black and white while retaining accuracy. Everything is a spectrum
Was a great video, then you had to throw Trump into it.
13:17 “If instead we placed better metaphors … in the curriculum from the beginning, these headlines would be quickly dismissed as nonsense.” … and that’s exactly why they still haven’t replaced Mendel and other “lies to children”, 10 years after the Genetics Pedagogies Project 🙃 a public trained to think in oversimplified, deterministic terms is easier to manipulate! I learned a lot from your video and will be sharing it with others 🙏
Life is really just existence boiled down to 2 facts. 1. if it exists, it must have come into existence. 2. If it exists, it must have existed since it came into existence. Thus life is simply that which perpetuates its existence in a certain form favourable to continued existence. This perpetuation must have come about by pure coincidence, and maintains itself in a cycle that actually bootstraps itself.
Well done, very sly way of embedding the idea of trans into a scientific language. 🎉
Great video won a loyal sub!
Waddington landscape is exactly what I needed to explain autoregressive LLM’s
If the directing paddles represents specific genes, then does the moving ball represent the process in which the proteins that make up the body parts are synthesized??
always funny watching some young guys who said some dumb shit about genetics. 😀 I know biology professors (genetics is their specialization) who have over 90 years old and they can't say so many thing for 100% sure as this guy did.

I've read "The Selfish Gene" and "The Blind Watchmaker." Everything he said in his books are just bullshit.
I would say that thinking of biology and physics in this way is kinda limiting. I mean, physics is just taking some principles and applying to predict certain things (events, probabilities, values, etc.). While biology it focuses mainly in organisms. The difference is blurry when you are trying to predict patterns in organisms, because organisms are made out of atoms and their interactions. Like it is said in the video it is useless to say that this happened because this particle moved to this place, you need to interpret the results that the methods of physics give you, and for that you need abstractions. For example physics predicts electrons moving in an atom in a certain way, we can use that abstracting the core idea (orbitals and bonds) and now you have chemistry, that's why you have chemista and physicists working sometimes in the same topic, because they are basically talking about the same thing. It is a bit misleading that it's neither chemistry or physics, because of an arbitrary line that makes these words ambiguos in the context. Analogously for biology it's the same, You have from animals to peptides and enzymes moving from here to there, which and it is of course biology. But these are simply different abstractions of physics, because they are more useful and digestible for the human mind. You could predict every atom movement ever but without these abstractions you could not understand it. Again abstracting to these levels are not ignoring the physics, because it's physics, just making it easier to see.
Come back bro, your the only genomic and biology youtuber that actually teaches things I've never seen before and doesn't make wanna eat 600 rusty nails. Also whenever you wanna come back, dont come back if your not ready.
Does temperature like fever has an impact on protein behaviour?
i dont get this video, they are still machines and its all clockwork driving by thermal energy and chemical reactions. the proteins are not sentient and choosing to do what they do. even as complex as they are or as soft and jiggly as they are still used for specific functions, we don't have uni protein that does everything there is still specialization even though their complexity allows them to full fill many roles.
Dawkins' book makes good toilet paper
Anarcho-communism mention?!?!? Hell yes!
Actually liked this, 🤔 ✌️😎
You all have a problem when using words and get confused, this is a great word salat. No, science and politics dont go together, that's raw bs. Read the tyranny of words, you need it, and BTW, this video is the worst you've made so far in UA-cam, like really bad
The "process ontology" does not work either; this became clear to me early in life, asking the the proverbial "who or what am I?" You can't equate the self to a process any more than you can to a static object or collection. My reasoning came from the "maybe I'm my body's activity" line of thought, which turned out to be absurd. If I was my body's activity I would BE MORE when I'm running than when I'm sitting. But BEING is ONE, is my experience; it has no scale or degree; I cannot 0.7 BE, nor 5.2 BE. There is no BE MORE, and therefore no activity, bodily or otherwise, can be self.
Excellent video! I almost dismissed it as "clickbait" from the title; glad I clicked on it. Liked and subscribed.
I come back to this video again and again and it’s beautiful 😊 as a geneticist I hope to change these paradigms in the future
