That's pretty much the idea - if you're planning to use the theory of evolution to promote or justify bad things, don't do that. Or good things, for that matter - shovels aren't innately good, either.
And don't let the shovel do it either.
The theory of evolution is unlikely to visit you during the night, unbidden and with malice in its heart ;)
Unlikely because "it" is where the scientiae go and return with grand pronouncements: "it doesn't . . . it does." Perhaps it can do all these things without a shovel and in plain daylight. "It" is silent until speech interrupts.
