Just as a matter of clarity here, I'm no expert in the area whatsoever, however when I think of evolution I do also think of how evolution started. Perhaps where the bridge is gapped is in that there is more than one there theory as to how it kicked off. The point is abiogenesis sometimes gets bundled with other theories. At least for me that's how I think of it. it's I'm sure technically wrong.
In short I don't see how evolution (natural selection, life creating life yada yada) happens without some sort of event where non-living elements result in protozoan that then subsequently all life was formed.
It started somehow regardless of what you call it.
