Analysis of synthetic scenarios. Two evolutionary histories (left column) of four species with traits, either appearing through duplication and divergent selection (case A), or also considering convergence and horizontal gene transfer (case B). The different scenarios take sampled niches (described by the traits which are needed to inhabit them) and, depending on the OTUs found and on the analysis of neutrality, the inferred PCGs and types of niches are shown. These scenarios are analysed in detail in the main text
