Five decades have passed since the proposal of the molecular clock hypothesis, which
states that the rate of evolution at the molecular level is constant through time and among …

Madagascar is one of the world's hottest biodiversity hot spots due to its diverse, endemic,
and highly threatened biota. This biota shows a distinct signature of evolution in isolation …

Ferns are the second-most diverse lineage of vascular plants on Earth, yet the best-sampled
time-calibrated phylogeny of the group to date includes fewer than 5% of global diversity …

Phylogenetic relationships, divergence times, and patterns of biogeographic descent among
primate species are both complex and contentious. Here, we generate a robust molecular …

Tertiary macrofossils of the flowering plant family Leguminosae (legumes) were used as
time constraints to estimate ages of the earliest branching clades identified in separate …

The first edition of Tropical Rain Forests: an Ecological and Biogeographical Comparison
exploded the myth of 'the rain forest'as a single, uniform entity. In reality, the major tropical …

Current hypotheses that use visually guided reaching and gras** to explain orbital
convergence, visual specialization, and brain expansion in primates are open to question …

Tropical biotas provide excellent settings in which to explore mechanisms of evolutionary
diversification, yet these processes remain poorly understood. Pioneering work on …

Primates have long been a test case for the development of phylogenetic methods for
divergence time estimation. Despite a large number of studies, however, the timing of …

DNA techniques, analytical methods and palaeoclimatic studies are greatly advancing our
knowledge of the global distribution of genetic diversity, and how it evolved. Such …
