The recent discoveries of exteremly simple and durable bacteria in deep sea vents has shifted the focus away from shallow solar heated pools. It is very likely that life first generated there or at least was incubated there if it did initially arrive via a meteorite from another wet planet. It would have been safe there from the intense solar radiation and the extreme climate fluxuations resulting from the numerous astreroid impacts of the time.
