Diversification rates vary over time, yet the factors driving these variations remain unclear.
Temporal declines in speciation rates have often been interpreted as the effect of ecological …

Biodiversity today is huge, and it has a long history. Identifying rules for the heterogeneity of
modern biodiversity—the high to low species richness of different clades—has been hard …

For centuries, biologists have been captivated by the vast disparity in species richness
between different groups of organisms. Variation in diversity is widely attributed to …

Unravelling the drivers of species diversification through geological time is of crucial
importance for our understanding of long-term evolutionary processes. Numerous studies …

The fossil record shows that the vast majority of all species that ever existed are extinct and
that most lineages go through an expansion and decline in diversity. However …

Aim The importance of quantifying the contribution of historical processes in shaping current
biodiversity patterns is now recognized, but quantitative approaches that explicitly link …

The uneven distribution of diversity is a conspicuous phenomenon across the tree of life.
Ecological opportunity is a prominent catalyst of adaptive radiation and therefore may alter …

Microendemicity, or the condition of some species having local ranges, is a relatively
common pattern in nature. However, the factors that lead to this pattern are still largely …

Evolutionary dynamics operating across deep time leave footprints in the shapes of
phylogenetic trees. For the last several decades, researchers have used increasingly large …

Phylogenetic trees are representations of evolutionary relationships among species and
contain signatures of the processes responsible for the speciation events they display …
