Organized by KLI

Topic description:
Long-term morphological stasis is an important pattern in macroevolution. According to one strand of thinking in evolutionary biology, stabilizing selection is the whole story about stasis. Following philosophers such as Kim Sterelny and Jonathan Kaplan, I argue that this extrapolationist approach is misguided. Other potential explanations of stasis invoke population structure, extinction selectivity, habitat tracking, and developmental constraints. I’ll argue that the challenge of explaining stasis is best understood as a problem of model integration, and that stasis might not be a unitary phenomenon. The same pattern could be generated by different processes in different cases.
