Jeffrey Silberman, a professor of biological sciences, isolated a new unicellular anaerobic eukaryote, and worked with former graduate student Matt Brown and others in the lab of Andrew Roger at Dalhousie University in Halifax, Nova Scotia, Cananda, on the genomics and description of this organism, which they named Pygsuia biforma. Brown, now a biology professor at Mississippi State University, is the lead author of the study, which was published August 28 in Proceedings of the Royal Society B.
“The importance of this finding is that it helps us decipher how multicellularity evolved,” Silberman said. “It demonstrates that some genes and proteins that most people think are specific to being multicellular in animals are already present in their unicellular relatives. It is as if the genetic toolkit for becoming multicellular was assembled and modified bit by bit in the single-cell lineages that share a common ancestry with animals.”
