You also need to consider the audience. Like me, for instance, a total dumb ass on small wriggling goopy things. Human jaws are the maxilla and mandible - but we don't refer to them separately. I think just saying "jaws" in this context is okay as well.

@Zaihanisme 4 года назад

MattExzy he was making a distinction because the video stated that the jaws of rotifers are called trophi, which is incorrect, as trophi are the parts of the mastax, which would be the better equivalent to jaws.

Rotifers are the one microorganism I’ve been able to keep in a petri dish for years... you forgot to mention the nifty horizontal gene replication some species are capable of.

@andrei1637 4 года назад

They are making clones?

@elizaalmabuena 4 года назад

The ones I got a hold of were bdelloids. They are know to reproduce asexually through parthenogenesis but they also do horizontal gene replication which prevents full on clones. They take ‘you are what you eat’ to a whole new level, stealing bits of DNA from those cells.

@Ellyerre 4 года назад

@@elizaalmabuena Okay, you just blew my mind. I thought you meant they ate other rotifer cells and incorporate the genes in those cells into their own genome, sort of like bacteria transfer genes with plasmids, which would already be weird but I'm reading this paper that says they found bacteria, fungi and plant genes in rotifers and some of those genes were actually functional. So they literally gain genes from whatever they eat, which is wild. Also, I love that they are called 'ancient asexuals' because they have reproduced asexually for the last 25 million years. Thank you for getting me a new obsession!

No because they do not have a soul

@Talinoth 3 года назад

@@michaeldebidart Why not? Where's the cut-off? I agree that some animals are "more" or "less" than others in that department, but from even a tiny little rotifer, we're separated by *degree* rather than by *type*. A great, great degree. But still not entirely separate. I have seen remarkably intelligent displays by chimpanzees, gorillas, dolphins, orcas, parrots, ravens, dogs and cats. If I'm required to believe *every* human has a soul - even the absolute dingbats among us who are stupider than a lot of people's dogs - then why can't other intelligent animals have souls? And what hard cutoff separates them from other animals? It seems more likely to me, that tiny animals with tiny brains have commensurately tiny brains and/or souls. But in the end, they're not so different from us. That's where we - where all animal life began, evolving to this point step by step.

Nature has the general rule; the bigger you are, the more susceptible you are for extinction. Small animals tend to survive extinction events, especially micro lifeforms. There is strength in numbers.

@Gun4Freedom 4 года назад

@1234 Although you might think that with more generations there'd be more genetic change, that's untrue. Keep in mind that a majority of microorganisms asexually reproduce, so there's not as much mixing of genes. Some of them can transfer genes to eachother, but that's not done with intent or precision, and it's only some of them. With a shorter lifespan, there is also less time for mutations to occur. Quantum physics behaves at the same rate regardless of the overall size of the organism. Much of the microbiome exists in aqueous environments, which is very effective at reducing ionizing radiation, one of the bigger drivers of mutation.
