Using microRNA to Study Evolution

by Chris on September 28, 2009

Dartmouth Biology professor Kevin Peterson, working with researchers from several institutions, has developed a breakthrough technique to study the evolutionary relationships between species. His research, published on Sept. 15 online in the Proceedings of the Royal Society B [abstract], provides answers to long-standing questions about the evolution of segmented worms. (read more)

In the three decades since RNA was first sequenced in 1975, scientists have been intrigued by how the genome relates to life, studying has been limited to looking at only one gene at a time. Now Erik Sperling GRAD ’11, a graduate student in the Yale Geology and Geophysics Department, and his colleagues have changed that. Staff reporter Rachel Gilmore investigates.

In research published Tuesday, the team reported their findings that microRNA or miRNA, single-stranded regulators of gene expression, can help us chart evolutionary history — and they used it to correct a misunderstood evolutionary fact.  (read more)
