Punctuated equilibrium is a biological theory that regards evolution not as a gradual process by which one species slowly and continuously transforms into another, rather a process in which species were remaining stable for long periods and then have dramatic change in isolated short bursts.

(A) rather a process in which species were remaining stable for long periods and then have dramatic change

(B) but as a process in which species remain stable for long periods and change dramatically

(C) but a process in which species remain stable for long periods and then have dramatic change

(D) yet as a process in which species remained stable for long periods and change dramatically

(E) but also as a process in which species were remaining stable for long periods and were changing dramatically
