Ancient fossils give clues as to when features of modern tetrapod bones emerged.

Virtual investigation of the 3.67-million-year-old skull of 'Little Foot' using synchrotron radiation reveals histological details of Australopithecus dental and bone tissues.

A three-dimensional investigation of extinct-tetrapod limbs shows that even though bone elongation and blood-cell production are intimately related to mammal long bones, these functions actually appeared successively in tetrapod evolution.

COVID-19 CG is an open source web resource that allows vaccine, therapeutics, and diagnostics developers to track SARS-CoV-2 mutations and lineages by location and time.

The closest living relatives of animals, the choanoflagellates, switch from a flagellate to an amoeboid phenotype under confinement.

A series of selective events, each improving fitness relative to an immediate predecessor, can result in organisms that are less fit compared to a distant ancestor.

Experiments on yeast cells that are hosts to a killer virus confirm that natural selection can sometimes reduce fitness.

For many bacterial species, recombination dominates genome evolution and phylogenetic patterns that have so far been assumed to reflect clonal relationships, in fact reflect variation in recombination rates across lineages.

Distinct selective landscapes in mosquito and human cells shape dengue virus genetic diversity and highlight mechanisms of host adaptation in arboviruses.

A set of adaptive mutations affect only a small number of phenotypes that matter in the evolution condition, and yet contain substantial latent functional diversity revealed in distant environments.
