Event Description

The Origin of Microbial Species: Peering Into Microbial Genomes to Understand Microbial Adaptation Into New Ecological Niches

Presenter: Rika Anderson, University of Illinois at Urbana-Champaign
When: November 25, 2014 3PM PST

The evolution and spread of microbial communities into new ecological niches has profoundly shaped our planet’s biogeochemical cycles and habitability over geological time. However, the molecular mechanisms of microbial adaptation to the environment are not well understood, yet understanding these processes can give us insights into how microorganisms have co-evolved with the planet throughout its history. We are examining archaeal genomes isolated from Yellowstone hot springs to ask how the acquisition of new genes affects the evolutionary trajectory of a microbial lineage, and to determine what types of genes are most frequently transferred as a means to adapt to new environments. Through these techniques we can also begin to reconstruct evolutionary history, and trace these processes to the origin and spread of key metabolisms during the Archaean era. Through this we hope to shed light on the mechanisms by which microorganisms adapt to new ecological niches, and to understand how metabolic networks spread across the biosphere.
