Solenodon

Using an atypical assembly strategy, researchers tackled the genome of Solenodon paradoxus, an endangered venomous, shrew-like animal from Hispaniola.

Using haplotype profiling, phylogenetics, and other analyses, researchers retraced sickle allele emergence to a single event occurring roughly 7,300 years ago.

Researchers discovered thousands of candidate functional elements by searching diverse mammalian genomes for regions of accelerated evolution within highly conserved sites.

Research on phages in CRISPR-Cas9-containing Escherichia coli indicated that pressure exerted by the bacterial defense system can boost phage mutation frequency.

Still Evolving

A new paper in PNAS finds that people are still evolving, but with increased pressure on weight and decreased pressure on intelligence.

Tasmanian tiger/thylacine/Tasmanian wolf

A genomic analysis of the Tasmanian tiger pointed to early genetic diversity declines in the species, while offering clues to convergent canid features.
