After more than six months of filming and countless tweaks, Jan van IJken was able to shrink what would take around four weeks in nature down to just six minutes of otherworldly beauty. If you'd like to learn more, read on here: on.natgeo.com/2DVOnUN
great job love your channel ❤❤❤❤❤❤❤❤❤👍👍👍
It looked like it started as a giant cell that divided into smaller cells that in total still had the same volume as the mothercell. Is this truely what happened
@@nelsonvenema3614 Yeah, naturally. Cleavage divisions of the zygote do not involve growth.
@@nelsonvenema3614 Good question, but obviously not. In the course of these 4 weeks they have some moments in which they zoom out to keep the growing embryo within frame and focus.

The cell splitting was nuts crazy how everything knows exactly what to do
I was thinking the same thing !
I dont get it how the cells know what to do and when to do it.
Like creating his eyes.
But also what we dont see
On the inside his brains and organs .... really amazing
did you ever heard about.....
*genes* ?
They are basically one big to-do list for organisms
People know about that how that works since a couple decades ago.
The crazy world only god knows
@@elkirb9997 *Yes* . Also they follow genes because if they don't ,organism would likely die due to some fatal mutation : D. .They are basicly just multiplying wich builds organism cell by cell.It's like I would ask you why are you mating with others?.That's just how it work's
Knowing cells divide is one thing but actually seeing it is shocking. This process feels both scientific and metaphysical at the same time.
The cellular programming to be able to accomplish such a thing is remarkable. Even our scientific understanding of it is dumbed way down to our level of comprehension. The science is not at all a satisfactory alternative to metaphysical.
Atheists be like "everything is random and there is no unifying energy behind the meticulous order and structure of the universe"
@@therealestg9 Science is great at helping to understand that order, but not where the order came from. Using science in the place of God is why they have to use words like "Accident" and "random", which are just words for "we can't figure it out, so let's just ignore it and pretend what we do know is the ceiling".
@@AClRCLEOFLlGHT nah that just mean let's ignore it until we have the tools tp understand it, knowledge doesn't come over day. You have to accept you don't know if u want to make progress
@@therealestg9 I dont think that is the atheists view, I think there view is that they dont belive in god.

Salamander: *happily starting to live without knowing that 5,5 million people have witnessed its birth*
@Siggesatan I'm an antinatalist, so I don't think it's ethical to start a life without being able to gain the consent of the being beforehand.
When you say it is "amazing," biology itself might be amazing, but that doesn't mean it's ethical.
@@danielt.4330 I really hope you are joking
@@tristanfaulkner6003 Why do you hope I'm joking? And I'm not, I'm expressing my thoughts. If you think I'm incorrect, why do you think so?
@@danielt.4330 Well, that would mean that you view life itself and existence as morally wrong. No being "consented" to it's own birth because no being exists in this reality before it's birth. What is the alternative to existence? There would just be nothing. The universe would have little meaning without any living thing to experience it. Even if there are other planes of existence it would still mean that this one will completely go to waste and lose all meaning. Whether life exists for a reason or by chance, it exists and it doesn't deserve to be frowned upon for continuing to exist.
@@tristanfaulkner6003 How does your comment, in any way, address the issue that I raised?
I didn't ask about how you feel the consequences of such actions would conclude. I stated that "starting a life without gaining consent beforehand is unethical."
Do you disagree with my point? And if so, why?
And furthermore, saying, "it exists and it doesn't deserve to be frowned upon for continuing to exist" is not what I did. I didn't "frown upon" it for existing - I frowned upon humans for engaging in specific activities that start new life. There's a difference.

It's the salamander's version of the Truman show.
Amazing how you can see the process of Gastrulation (cells apparently "flowing inside" make up the mesoderm) start at around 1:00 and Neurulation at 1:46 (formation of the neural tube, which will make the central nervous system).
Human embryos undergo the same processes and are quite similar at early stages of development.
How do the cells know how to arrange themselves? I understand DNA encodes this, but not sure how exactly it works.
@@mirabelch5439 Cells guide themselves by following migration factors, substances encoded by DNA, as you say. Imagine someone in a room puts perfume on, the closer you get to them, the stronger the smell will be. This works similarly. For example, cells which are supposed to go to the developing heart, and become heart cells, will have receptors for factors that “smell strongest” in the mid thorax.
So when an organism develops, key structures like the spine or the digestive tube will release these substances locally and cells in migration will guide themselves to their final destination by detecting them.
It is all about how they play with the intensity of these “smells”, which allows cells to adopt a very specific location.
For complicated processes like these, there are thousands of genes which are expressed during embryo development and, after birth, never used again.
@@rafas3941 to summarize, 1) spatially distributed transcription factors (maternal contributions ) and 2) intercellular talks(paracrine signals) .
@@benjamin4321 there are genes called structural genes, which encode the functional molecules making up the “perfume”. But then there’s also regulation genes, encoding molecules which will determine when, where and for how long the structural genes are expressed.
These regulating molecules (proteins) act through various mechanisms to silence/activate genes. It is an extremely complex system: a molecule regulates a molecule which in turn regulates others, and so on. The moment when different regulating proteins interact with one another determines the moment when genes are expressed, and thus when different types of “perfumes” (transcription factors, etc) are released.
@@rafas3941 im curious. since there would be more perfume at any direction of a given radius. in other words. the space 1nano-meter from the source would have the same amount of perfume at the north, south, east, and west direction. and the space 5nano-meter away would have less perfume in any direction. you get the point.
however, the cells that would migrate to form the head has to know to travel in only one direction e.g. north instead of dispersing in all direction and stopping at the same radius away from the source. how does the cell know and decide to only send the precursor cells for the head to only ONE direction?

Amazing timelapse. I would have loved to see a timer on screen to see the growth compared to the actual time.
I too thought about it...
i hope i don't ruin this, but there is a thing called genes. it is like a instruction manual for organisms.
@@pleeppants1712 Haha, I know that.
It actually makes me want to pause the development of the embryo very early on (say when it's at 4 cells), rotate one of the cells (nucleus and all) by 90 degrees, then let it resume developing and see what happens. Would that destroy the embryo? Will it survive but come out all wrong? Will the cell rotate back to its original orientation? Does cell orientation matter at all?

Yes. Think how complex it is just to build "self driving cars" with computers and sensors to navigate around traffic, that it hasn't even been done yet. But for living things, the DNA builds all the senses, the brain/ mega processor that processes real time feedback from all the sensors, detects threats, makes decisions, learns from experience, adapts to the environment.

This is different to conventional mitosis outside of developmental biology where a cell grows and THEN divides into two daughter cells, essentially doubling the total volume of cells. Also, notice how you can see the red blood cells flowing through the circulatory system. Just a few interesting points.
Anyway, the way these cells actually coordinate themselves is by secreting substances called morphogens. These morphogens then diffuse around the surrounding mass binding to the cell surface of each other. The area where the morphogen is produced is very high in the amount of the morphogen (as it was produced there). As you move further and further away from the source, the amount of morphogen decreases. In this way, the cells can "know" where they are in relation to the rest of the cells and embryo by different amounts of morphogen binding back to their cell surface membrane. They can then respond by activating or silencing certain genes. This happens throughout the process allowing cells to differentiate and specialise into the different tissues and organs eventually resulting in the salamander. The world of developmental biology is an incredibly clever and fascinating process.
thanks for this comment, I just learned something new =)
@@RadeticDaniel No problem, happy to help ✌🏻
Thank you! I was so confused by that...to the point where I thought we were not looking at cell division, and simply something that looked like it.
@@martinfraga4329 Oh yes, it’s still cell division so you’re completely right.
All this finally reflects that there is a SUPERPOWER above and beyond human comprehension that we call by different names..OMG!
Because we’re here 😊
That was absolutely amazing. Thank you, Amit, for sharing your passion from beyond the veil. RIP
