The Advantage of Phenotypic Plasticity in Evolution

Hard Biology Evolution

Adaptive evolution refers to the process through which populations evolve traits that enhance their survival and reproduction in specific environments. A classic example can be seen in Darwin's finches, which evolved various beak shapes to exploit different food sources in the Galápagos Islands. Recent studies have shown that shifts in environmental conditions can lead to rapid evolutionary changes in traits among these finches. Additionally, these changes often involve the interplay of genetic variation, environmental pressures, and competition. Consider the implications of this adaptive evolution on the survival of species in changing environments.

Based on the principles of adaptive evolution, which statement best describes the evolutionary advantage of phenotypic plasticity in light of changing environmental factors?

Phenotypic plasticity allows organisms to maintain the same phenotype regardless of environmental variations.

Phenotypic plasticity provides organisms with the ability to adjust their traits based on varying environmental conditions.

Phenotypic plasticity decreases genetic diversity within a population by producing uniform traits.

Phenotypic plasticity ensures that all offspring will exhibit the same fixed traits in any environment.
