Fig. 1From: The genome of a vestimentiferan tubeworm (Ridgeia piscesae) provides insights into its adaptation to a deep-sea environmentA species tree of R. piscesae and 14 metazoans. Single-copy orthologs were used to reconstruct the phylogenetic tree. The divergence time between species pairs was listed above each node, and 95% confidence interval of the estimated divergence time was denoted as blue bar. R. piscesae diverged from R. pachyptila approximately 33.7Â Ma agoBack to article page
