A new fossil sheds light on the evolution of an aquatic lifestyle in extinct reptiles and supports a close phylogenetic relationship between archosaurs (crocodiles, dinosaurs, birds, and kin) and turtles.

The use of within-host pathogen genomic sequence data can be used to improve phylogenetic and transmission estimates.

HIV transmissions into intervention communities from control communities in the Botswana/Ya Tsie trial were similar to the reverse at baseline, and 10 times more common post-baseline, concordant with a predicted benefit of a universal test-and-treat HIV prevention intervention.

Phylogenetic evidence suggests that the majority of HIV infections occurring in the UNAIDS Fast-track city Amsterdam continue to have an Amsterdam resident as source, indicating that the majority of HIV infections in Amsterdam could be prevented through city-level interventions.

A new tool allows researchers to dive into phylogenetic trees containing millions of nodes using just their web browser.

The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.

Contrary to the high absolute number of white-eyes in other parts of the world, the Indonesian archipelago is the center of phylogenetic diversity of this great speciator.

Protein coding genes strongly support a sister group relationship between Placozoa and Cnidaria to the exclusion of Bilateria, contradicting previous phylogenies, which have likely been misled by pervasive compositional heterogeneity.

The PhILR transform uses an evolutionary model to overcome statistical challenges associated with microbiota surveys.

A large-scale phylogenetic inference of the ribonucleotide reductase family reveals a new distinct clade with implications on how nature adapted to environmental changes.
