I think there's a further difference - with some GAs (including GP, widely used by Sentient) the structure of the solution is "designed" alongside the parameterisation of that structure. Most DL work parameter tunes a structure that is hacked by human guesswork. The two approaches have strengths and weaknesses, and in no way does this make EC in general superior to DL, but perhaps different.
