No that's absolutely not true, every part of evolution happens for a reason and those we don't know, we research until we find out why

I think the point the other guy is pointing out, is that good and bad evolutionary traits are often connected - or more helpfully stated, evolutionary traits can have both benefits and drawbacks which don't immediately seem related to the same trait.

It's quite possible that octopi sex dementia is just a drawback to another trait which is very beneficial, so the dementia was just a bad aspect of a good trait that propagated forward. This happens all the time in different animal biologies.

No, that's what I am saying. They are saying that it's a random effect.

That is not how your comment reads. It reads like you think every trait exists as an advantage and propagates because it is a benefit. Plenty of traits propagate as side effects, which is how their comment read to me.

Not really, and I think it's because any unnecessary trait is an extra cost. But you can have your belief or even think we were magiced by an all powerful entity

[–] [email protected] 1 points 2 hours ago

unnecessary traits might not always lead to extra cost, and even then, the extra cost might not always lead to extinction.

the extinction usually happens when a trait that represents a disadvantage in a sufficiently heavy competition for survival. If the competition is low enough, the trait may survive.
