A single-celled microbe that revels in Earth’s most hostile salt lakes has the remarkable ability to transform its mote of a body into multicellular tissue when the pressure’s on.
“The advent of clonal multicellularity is a critical evolutionary milestone,” the international team who made this discovery, led by Brandeis University pathobiologist Theopi Rados, write in their new paper.
Haloferax volcanii is a member of the often-overlooked archaea domain, which looks quite similar to bacteria and yet have more in common with our own domain, eukaryota. Multicellularity is common in eukaryotes and rare among bacteria, and as far as we know, H. volcanii is only the second archaeon found to take this multicellular leap.
