Animal learning as a source of developmental bias

Area of Science:

• Evolutionary biology
• Developmental plasticity
• Behavioral ecology

Background:

• Learning is a key adaptive plasticity mechanism enabling organisms to adjust phenotypes.
• It generates adaptively biased novel behaviors and facilitates their transmission via social learning.

Purpose of the Study:

• To explore how learning-induced developmental biases influence evolutionary dynamics.
• To highlight learning's role in generating nonrandom phenotypic variation and environmental states.

Main Methods:

• Review of theoretical models and empirical data on learning and evolution.
• Analysis of different types of developmental bias in learning: adaptive, historical, origination, and transmission bias.

Main Results:

• Learning imposes direction on adaptive evolution and affects evolutionary rates and outcomes.
• Learning influences the probability of reaching global optima and impacts evolvability.
• Learning introduces novelty into phenotype space through specific environmental interactions.

Conclusions:

• Learning commonly generates plasticity before evolution.
• Developmental biases from learning significantly shape evolutionary trajectories.
• Understanding learning's evolutionary role is crucial for evolutionary biology.
