Endosymbiosis played key roles in the development of eukaryotes and plants. Roughly 2.2 billion years ago an archaeon absorbed a bacterium through phagocytosis, that eventually became the mitochondria that provide energy to almost all living eukaryotic cells.this was from Wikipedia, so it only happened once before the existence of eukaryotic organisms.if you want a pure theoratical approche then yes that’s possible at least in theory.if you want the other facade of this then possible is very different from propable,it’s statistically speaking impossible because you’ll need to add at least another condition which is that the target need to be on th verge of replication or have just finished replicating it self you might put around 2s at most
But it has happened in real world. Some vascular plants apparently have microalgae (which are eukaryotes) as endosymbionts of sorts.
Endosymbiont - Wikipedia.
Yup it’s a thing and to be honest it’s hard very hard , but we could do it, the idea is that the transformation is done on multiple stages and that the target should himself have a done endosymbiosis, and have organels that are already acquired by the host. The hardness come from the evolutionary cost, to do this you need to make a lot of copies and each time get rid of some of the target inuseful DNA so you’ll need to make a copy of it each time to reproduce, well in an abundance of ressources this is feasible
Are we sure this system isn’t too complicated?
It’s hard(as it should be or all things will have an eucaryote as an endosymbiont). But it’s not very hard to implement in fact I think the current endosymbiosis is harder.
The order of things will be
To make a normal endosymbiosis (as mentioned above) with an eukaryote that is preparing to replicate itself or has just replicated itself(it should be a decendent of a speciy that have endosymbiosis with a procariote (any mutation of the player spiciy could satisfy this requirements if the player have done an endosymbiosis with a procariote before).
this should be done once.
Then for let’s say 2 generation he will need to copy it self and the Engulfed speciy to acquire the organels it need
So it should be:
-either the player species or the target eukaryote species needs to already have an endosymbiont of it’s own
-the target eukaryote is engulfed either right before reproduction or right after that
-the next generation (?) the player will reproduce with the endosymbiont inside, acquiring the organelles they wanted from the endosymbiont
So for 2 generation the player will need extra phosphore and amoniac to reproduce, and this while not having the organels from the endosymbiont
Can’t the endosymbiosis process take a different amount of time from 2 generations? Like 3 generations? Or 4?
It’s a condition only on the target but since endosymbiosis is only done by the player then the target will be a distant decendent of the player after the player have done a procariote endosymbiosis
Oh I see. But why does the player have to have already endosymbiosized an prokaryote before endosymbiosizing an eukaryote?
That’s not necessary it’s just a number I threw at random a true one might need more and you need to remember that the time frame is 100million year!!!so even one looks a outrageous
We aren’t even sure how endosymbiosis took place, so perhaps it’s not so unrealistic to have the whole process from start to end take multiple hundred million years.
Because as I have told you the nucleus protects the genetic material of the eukaryote, but it does not protect the genetic code of the endosymbiont organels that the eukaryote acquired so it get passed on to the new host
Oh, so it’s more of stealing the target eukaryote’s organelles and not endosymbiosizing the entire eukaryote…
Yup, and it’s called secondary endosymbiosis
I see. So it pretty much degenerates the target eukaryote into a single organelle with more membranes than “normal”.
It means that it provides the same results of a procariote endosymbiosis but with higher cost.let me ask you is everything clear so we could make a final conditions?
Yeah. So it could happen if there are no longer any prokaryotes around to endosymbiosize.
Not really , you should have done at least once the endosymbiosis of an procariote before they get banished
And after that they might disappear from patches available to you, prompting you to endosymbiosize an eukaryote if you wish to commit endosymbiosis again.
