Scientists from the Andalusian Center for Development Biology in Spain considered that two domains diverged from this organism: Archaea (unicellular prokaryotic microorganisms lacking a nucleus but different from bacteria) and Eukaryote (multicellular organisms). The hypothesis of the origin of LUCA would answer the question from many researchers about its origin, appearance and where it lived, which, if true, would represent a revolution in evolutionary biology, the article said.
