Description
Elena Shematorova and George Shpakovski trace how the gene-copying machine of archaea changed over deep time, in a study from two thousand twenty-six. Archaea are single-celled life forms with one such machine, built much like a core machine in our own cells. One small part of the machine appears in only some archaeal groups.
New family trees for archaea let the team map that part across all known branches. Groups that lack the part show the most change in a partner part, often in trimmed forms. The authors read those changes as adaptation to the loss. The part was likely present in the shared ancestor of all archaea.
