Aim: At broad geographical scales, species richness is a product of three basic processes: speciation, extinction and migration. However, determining which of these processes predominates is a major ...

Researchers will reconstruct the process of evolution, determine relationships between species and build phylogenetic trees with greater accuracy thanks to new method for identifying extremely short ...

The mammal tree of life is a real leaner. Some branches are weighed down with thousands of species — we’re looking at you, rodents and bats — while others hold just a few species. Now we may have a ...

Resolving the timing and pattern of early placental mammal evolution has been confounded by conflict among divergence date estimates from interpretation of the fossil record and frommolecular-clock ...

In the world of phylogenetics, there's team sponge and team comb jelly. Which creature roots the animal tree of life—the simple sponge or the more complex comb jelly—has stirred fierce debate among ...

Using the largest and most informative molecular phylogenetic dataset ever analysed, evolutionary biologists were able to construct a new phylogenetic tree of jawed vertebrates. This new tree resolves ...

An asteroid strike 66 million years ago wiped out the non-avian dinosaurs and devastated the Earth’s forests, but tree-dwelling ancestors of primates may have survived it, according to a new study ...
