Viral Diversity Threshold for Adaptive Immunity in Prokaryotes

Posted on December 13, 2012 by Artem Novozhilov

A recent paper concerning non-Darwinian (Lamarckian) evolution and mathematical modeling. From the abstract Tracking this cost-benefit analysis across parameter space reveals viral mutation rate thresholds beyond which CRISPR-Cas cannot provide sufficient immunity and is purged from host populations. These results … Continue reading →
