@@rot_studios I think they underestimated their audience. Really, my bigger issue is with the _veeery_ simplistic mechanics rather than the aesthetic. Part of that may have been technical feasibility, but some of it may have been "accessibility" as well.

@ronenshtein7083 4 года назад

Mitochondria belong to Rickettsiales, a group of endosymbiotic gram-negative bacteria. Other members of the group cause typhus, rickettsialpox, and spotted fever. So it seems their entire lineage has been hanging inside the cells of other organisms for a long time...

@JoaoGabriel-hk8ub 4 года назад

@@bone8352 exactly! We tend to think it was eaten by an early eukaryote and it somehow managed to survive in the bigger cell and also exchange substances with it but it may well be that it happened to be a parasite that adapted to coexist with its host in a much more advantageous way by cooperating with it. It's thought that that's how many of the microorganisms that live in our guts and skin came to live with us in the way they do today so maybe it's not a rare phenomenon.

@BlackWolf42- 4 года назад

I had always looked for Euglenoids but never found them under the microscope. I've lived for almost 40 years thinking they moved in the opposite direction of their flagella (like a tail not with it's flagella moving ahead of the creature). If I did see a Euglena in the past, I've discounted it as 'swimming the wrong direction; keep looking.

What about those dust mites that are supposed to be in our houses? A while ago, I looked at a dead fly on the window sill and saw tiny scavenger bugs on it.

@shiddy. 4 года назад

at this scale, how affected are microorganisms by gravity? if they're on the underside of an object, do they need to use any extra energy holding onto it in order to not fall off?

@marc-andreservant201 4 года назад

They are affected by gravity just as much as any other organism. Acceleration is a constant 9.8m/s^2 as demonstrated by Galileo. What does change is surface area to mass ratio. As the microbe becomes smaller, it can adhere to surfaces through the surface tension of water or intermolecular interactions, and it would actually take some effort to jump off.

MITOCHONDRIA ARE THE POWERHOUSE OF THE CELL!

@ariochiv 4 года назад

Currently living primary osmotrophs may be derived from phagotrophs, but surely the earliest cellar organisms were also osmotrophs? Photosynthesis is a fairly derived function, but so is predation... and further, predation requires pre-existing organisms to prey upon. Maybe bacteria already existed for the first cellular organisms to prey upon, but it still seems more likely that the first cells formed from simpler organisms that grouped together in a colony. That the first cells formed already with the ability to hunt for prey seems hard to swallow... in the macroscopic world, active predation didn't really become a thing until the Cambrian Explosion, some 100 million years after the first multicellular forms.

@djinnisequoia 4 года назад

I think about that kind of stuff a lot. Like sometimes it seems to me that for any of these organisms to have ever engulfed another, you almost have to assume some kind of intent..I mean, how could it happen by accident? But if there was a time when they didn't eat, when life first appeared, were they just very short-lived? Or very efficient?

@ariochiv 4 года назад

@@djinnisequoia Well, if the first life developed around hydrothermal vents, which seems ever more likely, then the first organisms most likely derived their energy directly from the thermal gradient around the vents (chemically through processing of hydrogen sulfide, etc.), and predation probably developed as a secondary way of deriving nutrients.
