Ask HN: What interesting thought did you read on HN but couldn't find later?
An article about some species of octopuses that have a relatively high IQ, but since the parents die before their offspring comes to life, every generation have to relearn everything from scratch.<p>IIRC, the lack of inter-generational communication deprived this species from developing to the level its IQ permits.<p>I wish I can find that piece again!
