Abstract

A theory based on biological evolution that explains variations in organisms’ developmental and reproductive strategies in the context of environment pressures and available resources.

All life requires capturing and allocating energy; however, this energy is limited and comes at a cost – organisms cannot expend unlimited resources, maximizing all life domains simultaneously. Organisms must live within their restricted energy budgets, mandating tradeoffs to ensure they do not allocate more resources to a particular domain than are available. Selection favors strategies for allocating resources on the basis that they result in the greatest evolutionary fitness for the organism, respective of their environmental
