Which is a hybrid. My freshman bio teacher mentioned some "ring of evolution" to start off the chain, where several organisms had essentially mixed and matched pieces before tehy got to the point at which RNA codes became so complicated and individualized to certain groups that early speciation occured. I sadly do not have the notes on this from years ago, but I'll try to dig up some links to post.
Actually, I'm taking the opposite stance on Chandrasekhar here: what is the probability one organism magically has everything it needs to survive? Very low. What is the probability a bunch of different components developed, and then one aggressive proto-organism assimilated them all? Higher, but not by much.
The thing is, something like this becomes probable as time goes on. It actually becomes improbable for an improbable event not to occur given enough trials. If something is possible, it will likely happen at some point. That's the way the world works.
