The rapid accumulation of genome sequence data has made phylogenetics an indispensable tool to various branches of biology. However, it has also posed considerable statistical and computational ...

Having a reliable species tree is prerequisite for understanding evolution, which is necessary for making sense of virtually every biological phenomenon. Traditionally, species trees are inferred ...

The fossil record is crucial for understanding the origins and diversification of amphibians and reptiles. New discoveries ...

Phylogenetics, systematics, and biogeography deal with the identifying, classifying, and understanding the relationships among organisms, including their geographical extent. Methods range from ...

McGill University researchers, in collaboration with Mexican scientists, have discovered two previously unknown species of crocodiles, one living on the island of Cozumel and the other on the atoll of ...

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 ...
