Indeed - what would be the evolutionary advantage for any creature to
proceed towards that specification?

I can just see the slogan -
'Bird Airlines. You want to fly to New York? *Grow feathers*!!'

I am sure I know where you are counting the 70 from. But what is
interesting is why?

Is it a certain form of selective vision (as distinct from selective
pressure :-) ) that has you starting from the first success, and not
from, say, Icarus, perhaps the first failure?
