Species evolve into new species by the small scale changes to its germ-line DNA over long time scales. The new species is not that different from its recent ancestors. It isn’t “Poof!”
Actually you can look at all organism (yes including humans) as vessels to insure that the DNA is replicated. The DNA, mutated through time is what is immortal.
I didn't think that there was any 'poof' involved in the evolution of species, and I perfectly realize the time-line involved.
My point was questioning the idea that there was NO life, then POOF! there WAS life.
