Figure 6. DDAR can explain patterns at the macro and micro scales.

The adaptive radiation of Anolis lizards in Puerto Rico (a) presents an initial lag. Under the maximum clade credibility phylogenetic tree³⁷, diversification did not start until the third colonization event or possibly, depending on species set and molecular markers, the second³⁶ (Supplementary Fig. 2). Data from ref. 37. Experimental evolution of the bacteria Pseudomonas fluorescens F113 (b) indicates that greater initial diversity (number of strains) promotes evolutionary diversification (fraction of evolved genotypes). The line represents a significant linear regression on diversity (P=0.0013). Data from⁴⁰.
