tap and sacrificing an already tapped land to get it's ability
No, for two reasons.

Evolving Wilds' ability has the tap symbol in its cost. If it is already tapped, then you can't pay that cost, so you can't activity the ability.

Worse, you can't even tap it for 1 colorless mana in the first place! Evolving Wilds has no ability that lets you tap it for mana whatsoever.

You can tap basic lands for mana because the rules grants them an ability to do so, but that ability is only granted to basic lands (Plains, Islands, Mountains, Forests and Swamps). You can't tap other lands for mana unless they have an ability allowing it.
