The influence of learning on evolution: a mathematical framework

Paenke, Ingo ; Kawecki, Tadeusz J. ; Sendhoff, Bernhard

In: Artificial Life, 2009, vol. 15, no. 2, p. 227-245

The Baldwin effect can be observed if phenotypic learning influences the evolutionary fitness of individuals, which can in turn accelerate or decelerate evolutionary change. Evidence for both learning-induced acceleration and deceleration can be found in the literature. Although the results for both outcomes were supported by specific mathematical or simulation models, no general predictions have...

Influence of plasticity and learning on evolution under directional selection

Paenke, Ingo ; Sendhoff, Bernhard ; Kawecki, Tadeusz J.

In: American Naturalist, 2007, vol. 170, no. 2, p. E47-E58

Phenotypic plasticity and related processes (learning, developmental noise) have been proposed to both accelerate and slow down genetically based evolutionary change. While both views have been supported by various mathematical models and simulations, no general predictions have been offered as to when these alternative outcomes should occur. Here we propose a general framework to study the...
