should i study applied mathematics at a shitty university? will i be able to land a job and maybe eventually relocate to the US or is it a waste of time? I'm about to graduate with a computer science degree but I dont think it's as flexible as math degree, however I am already 24 and I don't know if wasting 3 more years is worth it

Sponges and placozoans have no neurons. But they're more closely related to us than ctenophores, which DO have neurons.

This paper says poriferans and placozoans lost their neurons:
https://pmc.ncbi.nlm.nih.gov/articles/PMC4650130/

This one says ctenophores evolved neurology independently:

sounds right.
mercy is, on average, the closest planet to all the other planets. and the net velocity of an explosion is zero.
still, convergent evolution is pretty cool.
>>
>>16567252
Nope, it seems that ctenophores split off before the bilatarian/poriferan split. Ctenophores have nerves, muscles, and all sorts of stuff that sponges don't.

It means comb jellies independently evolved them.
They also use different neurotransmitters from everything else.

You don't think its more likely sponges just evolved away from neurons?

The attention whoring economy has made a mess of everything. "Look how stupid I am" pays and the more outrage one can attract, the more attention one gets. When this turns into clicks and ad impressions, it's easy to see why some go this route.

Scientists call animal rape "forced sex" and a lot of animals do it, male dolphins will get together and gang rape a lone female

this this mean that rape is not really a crime, just a reproduction strategy and really just sjws made it a crime when we started having societies?

Yes, for low ranking males in chaotic environments, e.g. India.

It has its risks too, you might easily get killed if you don't at least have some backup from the rape pack.

Lectures are the least effective way to learn, especially compulsory lectures. It's been proven over and over again that passive learning is shit, no one can maintain an attention span for the duration of an entire lecture let alone several lectures in a row, it's not personalized so it's either going too fast for people who can't keep up or too slow for people with better understanding, there's barely or no engagement, lecturers suck and barely give a shit, we could go on.

It's a relic of old times where textbooks were less comprehensive and harder to come by and there was no learning research. Lectures are obsolete.
>>
>>16565381
>and not what I said at all
What did you say then? Because to me you assigned more value to lectures than to self-study. I would say this is only true about the subjects you don’t give a shit about since you have no motivation to study them. Otherwise, self-study is superior as you can pace yourself, focus on things you need to focus and don’t have some random requirement over your head that this and that random problem need to be done by next Monday.

I am not a big fan of the analogy between ANN "neurons" and biological neurons. They function very differently and it in some way mysticizes ANNs.

Because brain neurons and ANNs work differently drawing a comparison like in the OP is a fools errand.

It's the same thing with "attention". It gets redditors excited like "omg it's conscious!". We don't even know what human attention is, but we can be pretty sure it isn't a dot product. We know more about how neurons work, which is enough to say they hardly resemble artificial neurons.
