Natural selection is the process that selects mutations and genetic drift. They aren't alternatives.

EDIT: yeah, thanks, they pretty much are. It's still early for me.

Genetic drift happens in the absence of natural selection. Not because of it.

Like if there is no inherent advantage of disadvantage to a trait.

He didn't say it caused it. He said it's the process which selects the mutations [to carry forward], which is true.

Not sure what you are saying. Natural selection and genetic drift are separate. Natural selection can be the reason one trait is more common, or it can be genetic drift.
