Mars: Mounting evidence for subglacial lakes, but could they really host life?

The report appears to assume abiogenesis took place on Mars, thus life is there today or perhaps, billions of years ago life evolved from non-living matter on Mars. The report does open the door to more drilling operations on Mars, looking for life. Since the BB event, there is ~ 4.352 x 10^17 seconds elapsed in the history of the universe until the present. Abiogenesis at work on Mars would take time too, how many seconds are needed for non-living matter to evolve into life on Mars?
