Los Ríos, Ecuador, CP: Biological Control 57 3 : Por ejemplo, los insectívoros no trre dientes, mamíferos que se alimentan de insectos. However, most analyses conducted in the past were based upon a single landmark configuration, leaving it unsettled whether the incorporation of multiple configurations may improve the rather poor performance of this data source in most previous phylogenetic analyses.

An unexpected branch in the Tree of Life sparked my extraterrestrial musings, but further investigation showed these entities were a bit closer to home. This was the line of thinking I had throughout this study. Well sort of - more like thinking from aliens, to a fourth domain of life, then to giant viruses, and, finally, to jumbo bacteriophage. I can explain. RNAP sequences have both enough conservation in all organisms to align them treee and enough diversity to distinguish what is a formal kid friendly definition from each other.

Thus, these sequences for RNAP are especially useful when constructing a Tree of Life that looks phlogenetic the diversity of all organisms. In this tree, we saw the usual major branches, or clades, belonging to the three domains of life: Bacteria, Archaea, and Eukarya. Surprisingly, though, this tree had an additional clade that branched away from the other domains. Thus began my mission: to phylogenetic tree in biology what creatures or entities encoded these intriguing RNAP.

Frank suggested they belonged to viruses, but my secret hope was that we discovered aliens or, at least, a fourth domain of phylogenetic tree in biology - that was never before seen due to some crazy feature, like existing in another dimension. However, a virus having its own RNAP can have advantages, like faster transcription and gene regulation independent of the host.

Encoding an RNAP as complex as the one used by cells requires the virus to have room in its genome for such a transcriptional luxury. Giant viruses are… giant! They infect eukaryotes and have particle sizes and genome sizes that sometimes exceed those of cells. Many are known to encode their own multi-subunit Phylogenetic tree in biology. Instead, they grouped near the Eukaryotes and Archaea. Now nearly convinced that we discovered aliens, my extraterrestrial fantasies were quickly dashed when we considered jumbo bacteriophage, which are viruses of bacteria that have genomes overbase pairs.

When we looked at other genes encoded by the phyoogenetic clade, we found hallmarks of dsDNA bacteriophage Caudovirales familysuch as tail and terminase proteins. Thus, finally, the case was closed. These RNAP did not belong to a plane, nor a bird, nor giant viruses; they belonged to bacteriophage. You can read more about these mysterious bacteriophage and the evolutionary implications of their RNAP biologt our paper: A distinct lineage of Caudovirales that encodes a deeply branching multi-subunit RNA polymerase.
