 Testing Adaptive Hypotheses, Optimality Models, and Adaptationism

Show Summary Details

Preview

This article discusses three claims about natural selection. The first claim is that natural selection played some role in the evolution of traits. The second claim is that natural selection played an important role in the evolution of traits. The third claim is that natural selection was a sufficient explanation of traits and that traits are locally optimal. An optimality mode was created for the generation of a prediction as to what a trait should be. By comparison, the testing and assessment of the predictions of optimality models have advanced. A related attempt is the testing of adaptive hypotheses with comparative data which are observations typically gathered from multiple species, and this provides an insight into an evolutionary trend.
