TY - JOUR T1 - A Central Limit Theorem for Punctuated Equilibrium JF - bioRxiv DO - 10.1101/039867 SP - 039867 AU - Krzysztof Bartoszek Y1 - 2016/01/01 UR - http://biorxiv.org/content/early/2016/05/11/039867.abstract N2 - Current evolutionary biology models usually assume that a phenotype undergoes gradual change. This is in stark contrast to biological intuition, which indicates that change can also be punctuated — the phenotype can jump. Such a jump can especially occur at speciation, i.e. dramatic change occurs that drives the species apart. Here we derive a central limit theorem for punctuated equilibrium.We show that, if adaptation is fast, for weak convergence to hold, dramatic change has to be a rare event. ER -
