Your typical Darwinian approach to evolution ignores pansperm

'Your trypical Darwinian' usually just argues that panspermia transfers the origin question to another planet, but does not solve it.

And therein lies the problem ~ the Darwinians transfer it to another planet, even though there's already evidence it's out there floating around in rocks and dust in great profusion, and making its way without the need for planets (or "deep gravity wells").

Panspermia does not make the mistake the Darwinians make of assuming (with evidence) that all life on Earth arises from a single source, or that it only arose once.

You do realize the single source, one-time-only hypothesis in the current paradigm is rather religious in its scope.

Actually, its a faith-based concept for which there is not the slightest evidence of any kind.
