IB Biology HL D4.1.5 Differences in Adaptation Survival Reproduction Questions

Analyse how selection pressure produces differences in adaptation, survival and reproductive success, and evaluate evidence for fitness.

Exam points

Analyse variation, selection pressure and fitness by linking an adaptive trait to differential survival and reproduction in a named population.
Evaluate predation or tolerance data to decide whether a trait is supported as an adaptation in its environment.
