The 201 genomes provided solid reference points, anchors for phylogeny -- the lineage history of organisms as they change over time. "Our single-cell genomes gave us a glimpse into the evolutionary relationships between uncultivated organisms -- insights that extend beyond the single locus resolution of the 16S rRNA tree and are essential for studying bacterial and archaeal diversity and evolution," Woyke said. "It's a bit like looking at a family tree to figure out who your sisters and brothers are. Here we did this for groups of organisms for which we solely have fragments of genetic information. We interpreted millions of these bits of genetic information like distant stars in the night sky, trying to align them into recognizable constellations. At first, we didn't know what they should look like, but we could estimate their relationship to each other, not spatially, but over evolutionary time." Woyke and her colleagues are pursuing a more accurate characterization of these relationships so that they can better predict metabolic properties and other useful traits that can be expressed by different groups of microbes.
