| contents | THE UNIVERSAL ANCESTOR AN UNFINISHED RECONSTRUCTION Arturo Becerra Luis Delaye Comunicación LUCA early evolution common ancestor Universal phylogeny horizontal transference The cenancestor is defined as the last common ancestor of every currently living being. Its nature has been inferred from the identification of homologous genes between archaea, bacteria, and eukaryotic lineages. These inferences indicate that the cenancestor had a relatively modern protein translation system, similar in complexity to that of a current cell. However, the key enzymes for the replication of genetic material and for cell membrane biosynthesis are not homologous in bacteria, archaea, and eukaryotes. Here, we briefly review the history of the concept of the last universal common ancestor and the different hypotheses proposed for its biology. 2016 artículo científico 2174-3487 https://www.redalyc.org/articulo.oa?id=511754471021 en http://www.redalyc.org/revista.oa?id=5117 Mètode Science Studies Journal application/pdf Universitat de València Mètode Science Studies Journal (España) Num.6 |
