Estimation of gene insertion/deletion rates with missing data

Lateral gene transfer is an important mechanism for evolution among bacteria. Here, genome-wide gene insertion and deletion rates are modelled in a maximum likelihood framework with the additional flexibility of modelling potential missing data.

North American Mammoth Diversity and Interbreeding

Here we report the sequencing of 67 new mammoths including non-Woolly specimens representing Columbian (Mammuthus columbi), Jeffersonian (Mammuthus jeffersonii), and pygmy (Mammuthus exilis) mammoths. In disagreement with the paleontological record, our analysis suggests that these mammoth species interbred, and may have resulted in specimens displaying intermediate Woolly-Columbian morphologies.

Eighteenth century Yersinia pestis genomes reveal the long-term persistence of an historical plague focus

The 14th-18th century pandemic of Yersinia pestis caused devastating disease outbreaks in Europe for almost 400 years. The reasons for plague’s persistence and abrupt disappearance in Europe are poorly understood, but could have been due to either the presence of now-extinct plague foci in Europe itself, or successive disease introductions from other locations. Here we present five Y. pestis genomes from one of the last European outbreaks of plague, from 1722 in Marseille, France.
