Miracle in the figurative sense, since although we do not know how cells evolved, quite plausible scenarios have been proposed.

The cells evolved into an organism and in the evolution created what was once a necessary condition of mind.

Together, the new cells survived, prospered and evolved into new and complex forms of life.

It was apparently another 2 billion years before more complex cells with nuclei evolved.

Such cells may have evolved from a coming-together of prokaryotes.

Simultaneously, cells have evolved major molecular defense mechanisms to protect themselves against viral infections.

These distorted cells, which can be detected in Pap tests, frequently evolve into a serious cancer if left untreated.

All the evidence suggests that cells have evolved to lie in the ordered regime, fairly near the edge of chaos.

A second model proposes that proto-eukaryotic cells evolved from bacteria without an endosymbiotic stage.
