Patrick Shih, Director of Plant Biosystems Design at the Joint BioEnergy Institute (JBEI) and faculty scientist with the Environmental Genomics & Systems Biology (EGSB) Division, collaborated with a team of researchers led by the University of British Columbia in a new study that has found that bacteria go extinct at substantial rates, although appear to avoid the mass extinctions that have hit larger forms of life on Earth. The finding contradicts widely held scientific thinking that microbe taxa, because of their very large populations, rarely die off. The study “Bacterial diversification through geological time,” published today in Nature Ecology and Evolution used massive DNA sequencing and big data analysis to create the first evolutionary tree encompassing a large fraction of Earth’s bacteria over the past billion years.
