The lifetime development history of an individual organism is called what?

Explanation:
Ontogeny refers to the lifetime development history of an individual organism, from fertilization through growth, differentiation, and maturation to its adult form. It specifically describes how an organism changes over its own lifespan, distinguishing it from evolutionary history of a species (phylogeny). The other terms don’t fit this idea: normalization is about adjusting data to a common scale, observation drift is a gradual change in measurement over time, and nonexclusion time-out is a reinforcement procedure used in behavior analysis. Ontogeny is the best fit for describing how an individual develops across its life.
