Resumo(s)
Over the previous decades, numerous studies focused on how oceanic islands have
contributed to determine the phylogenetic relationships and times of origin and diversification of
di erent endemic lineages. The Macaronesian Islands (i.e., Azores, Madeira, Selvagens, Canaries,
and Cabo Verde), harbour biotas with exceptionally high levels of endemism. Within the region,
the vascular plants and reptiles constitute two of the most important radiations. In this study we
compare relevant published phylogenetic data and diversification rates retrieved within Cabo Verde
endemic lineages and discuss the importance of choosing appropriate phylogeny-based methods
to investigate diversification dynamics on islands. From this selective literature-based review,
we summarize the software packages used in Macaronesian studies and discuss their adequacy
considering the published data to obtain well-supported phylogenies in the target groups. We further
debate the importance of Next Generation Sequencing (NGS), to investigate the evolutionary
processes of diversification in the Macaronesian Islands. Analysis of genomic data provides
phylogenetic resolution for rapidly evolving species radiations, suggesting a great potential to improve
the phylogenetic signal and divergence time estimates in insular lineages. The most important
Macaronesian reptile radiations provide good case-studies to compare classical phylogenetic methods
with new tools, such as phylogenomics, revealing a high value for research on this hotspot area
