I keep getting “Hardy-Weinberg principle” questions wrong in Evolution. What's the trap?

thinking the equation means evolution has stopped everywhere.

The usual trap: thinking the equation means evolution has stopped everywhere. How to avoid it: any deviation from p^2 + 2pq + q^2 = 1 is a signal that evolution is happening. Go back to the definition — allele frequencies stay constant in a large, random-mating population with no mutation, migration, drift or selection.

Memory tip

any deviation from p^2 + 2pq + q^2 = 1 is a signal that evolution is happening.
