I guess it's possible if this conferred some survival advantage.

It can be useful to work from the evidence to a conclusion instead of the other way round.

But wondering and philosophising can be fun :]

It would be cool if humans could pass knowledge via their offspring. But I always get worried thinking if I'm the asshole, I wouldn't want my kid to be one too.

If you were, you would.

Just has to not be a disadvantage.

Plenty of mutations have no purpose whatsoever and were unrelated to survival or manifest after reproduction so are not selected for or against.
