Researchers sequenced the genomes of two African wild dogs from Kenya and South Africa to tease apart population patterns and adaptations in the endangered animal.

A sequenced variola virus isolate from the 1600s points to a relatively recent common ancestor for viruses involved in 20th century smallpox infections.

Analysis of a gene associated with basal progenitor cell expansions in the brain suggests a single splice site change led to human-specific forms of the gene transcript.

Modern humans' population size has enabled weakly deleterious Neanderthal genes to be removed from the human genome, UC Davis researchers found.

Researchers established a high-quality version of the five-pacer viper genome and used it to take a wider look at snake relationships and adaptations. 

Researchers from the US and Germany assembled the genome of the small nocturnal primate and found a number of unusual insertions, including a complete mitochondrial genome.

By focusing on sequences that have diverged rapidly in humans, researchers identified regulatory sequences suspected of affecting neural processes.

Researchers used thousands of conserved sequences for more than 100 songbird species to reconstruct their diversification and historical expansion route.

A comparative genomics study suggests ants with obligate mutualist relationships to plants may have higher rates of molecular evolution than generalist ants.

Colugo

With the help of a new draft genome assembly, researchers have found that a Southeast Asian gliding mammal called the colugo is closely related to primates.
