Mono Monday - Origin

The Origin of cells was the most important step in the evolution of life on Earth. The birth of the cell marked the passage from pre-biotic chemistry to partitioned units resembling modern cells.

This transition has been called the Darwinian transition..................thanks to Wikipedia
