Series of progressive changes in a plant or animal (4,5)

Ross

I believe the answer is:

life cycle

(Other definitions for life cycle that I've seen before include "(In biology) series of changes in form that an organism undergoes" , "Stages in development" , "our generation" , "Process eg from egg to imago to egg ..." , "Jaques' speech describes this" .)

I've seen this clue in the Sydney Morning Herald.
