Lamarc-ian evolution.
Giraffes don't grow longer necks because their parents stretched them reaching for things. The fittest ones survived (aka ones born with taller necks) so this trait lived on.
Cubing has nothing to do with survival rates really, so this doesn't work much.
I forgot the example (so this isn't a very good post lol) but I think there have been a few instances where Lamarckian inheritance has been observed. Not as in giraffes and necks, but I think it was with toads maybe?
