My guess is they got the key random genetic permutation in the genome
that gave their brain the unique circuitry needed to be smart.

They were evolving and they hit the random mutation jackpot.

And the challenging nature of their environmental aided in the change
sticking because it was an advantageous change.

of course, the specifics of the genetic change, is the interesting part
