I think it's more accurate to say that we stumbled upon how to do these 
things through experimentation (why would anyone set out to deliberately 
do the things you described? They're not exactly obvious goals). I'm 
fairly certain that if you asked a fruit fly genetic researcher how to 
give them tentacles, they'd be stumped. We're still at the stage of 
breaking things to see what happens. Designing new features from scratch 
is a completely different proposition.
