Well, I voted chicken, but I could also argue for the egg.
The egg could be generalized as a pre-existing adaptation, but you can take that all the way back to 1-cells (as many did).
On the other hand, the multicellular animals procreated by celular division before developing the fancy gene exchange usually associated with an egg.
Just ask a farmer - you should get chickens first, then you'll get eggs for free!
