Figure 6From: Evolutionary origin of peptidoglycan recognition proteins in vertebrate innate immune systemEvolutionary rate in invertebrates. Poisson distances of six taxa are plotted against species divergence time. The divergence times depicted in the abscissa correspond to: 241 MYA (Diptera - Hemiptera), 280 MYA (Diptera - Coleoptera), 336.1 MYA (Diptera - Lepidoptera). MYA: Million years ago.Back to article page
