And a curious finding - in both liverworts and flowering plants independently, repurposing of this regulatory complex for lineage-specific traits is associated with duplication of the same component (the MYB transcription factor).

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?
Excited to share our latest work in @science.org on a new small polymerase.
