We do basically the same. And although eggs are an amazing example, all cells have an amazing set of "tools" to constatly test and either prevent or promote apoptisis. Imagine human eggs... They can remain in a halted phase of it's cell division cycle for decades (women are born with their eggs already there) enduring all sorts of threats that could and would damage it's DNA and other structures and lay in waiting until it is randomly selected to resume the cycle and maybe be fertilized.

Hi I want to explode myself except I'm going to try very hard to block myself from exploding myself until it's the right time and then I'll relax so I can explode

@@pilotavery _What in the fuck..._

@@persephone2706 This is what cells are doing. They try and blow themselves up when they are damaged and then they have another mechanism that tries to prevent them from blowing themselves up when damaged

@@pilotavery tsrtt

Now I can't unsee it too, but I love it

Now I cant unsee it. Cool. Thx.

lol, the whiskers make it surprisingly adorable for a microbe.

I was seeing a hair otter as well as a potato

@@idiotidiot5821 Oh thank you! Verisimilitude is a word I've been trying to remember for a long time now. I heard that when I was still watching Tobuscus.

@@chrono-glitchwaterlily8776 Supprised there isn't any Eggsrta comments, lol.

@@hdezn26 I'd assume there'd be more, though I'm hoping they're eggsagerating. They're more fun that way

If I had to guess, each time it bumps into debris, chemicals get released, and one of them signals the cillia to back up and turn. Then if that happens too many times in a row, the concentration of another chemical builds up to tell it to back up more and spin for a longer time.

@@maxwellsimon4538 So it has substantial subsystems of sorts. Every time I see these organisms, I feel smaller and less knowledgeable. It is truly fascinating.

maybe there are specialized organelles for the task? - Though I'm sure the real answer is a clear and decisive "It Depends". There will be several different strategies almost certainly

@@binghyong-baebang2236 I would imagine so. Like I said this was just my best guess. It would be awesome if JttMC did an episode on cell signaling, because it's such a fascinating subject.

Roombas. They ride on tiny Roombas. 😁

@@ashleyliu1255 I watched another video about reproduction and he referred to Muller's Ratchet as the mutation that occurs with asexual reproduction. This series covers a lot of territory and is so challenging. 👏😍

Thankfully, the truth of our (human) species is somewhere in the middle, since both sperm and eggs are necessary for creating life. If only one of them was needed, that would have created further discrimination and inequalities within the human society.

I'm not an expert, but from what I've read/watched it's possible for the first few cells that the zygote (fertilized egg) divides into to be separated and still have them develop into mature organisms. Might not be ideal in an egg situation, since the amount of nutrients is limited, but that's how mammals get identical twins - one zygote's first few divisions got separated, and the 2 copies successfully implanted. I actually just learned this by perusing Wikipedia: when the egg begins development of a new organism, it divides until it has 16 copies of itself, and this ball of 16 cells is called a morula ( en.wikipedia.org/wiki/Morula ). Once that occurs, somehow (probably through chemical densities?) they coordinate the creation of an inner hollow space, and the mass becomes known as a blastocyst ( en.wikipedia.org/wiki/Blastocyst ). I would think that identical twins occur when some of the cells during the creation of the morula de-adhere from the main mass, and essentially begin creating *another* morula. But, like I said, I'm no expert. Just very biology-curious.

I mean Hank the narrator is also a host from SciShow

@@AaronShenghao that's what I mean. Seems like they're underselling it with the "hundred years" claim.

It was mainly around in the 1700s and earlier, I think by sometime in the 1800s it was mostly a dead idea. Though replaced by other debates about how things worked

I wonder how they accounted for the child's resemblance to the mother

Is it creepy that I kinda wanted to see it do that on camera?
