RT Journal Article SR Electronic T1 Late mitochondrial origin is pure artefact JF bioRxiv FD Cold Spring Harbor Laboratory SP 055368 DO 10.1101/055368 A1 William F. Martin A1 Mayo Roettger A1 Chuan Ku A1 Sriram G. Garg A1 Shijulal Nelson-Sathi A1 Giddy Landan YR 2016 UL http://biorxiv.org/content/early/2016/05/25/055368.abstract AB Pittis and Gabaldón1 recently claimed that the mitochondrion came late in eukaryotic evolution, following an earlier phase of evolution in which the eukaryotic host lineage acquired genes from bacteria. Here we show that their paper has multiple fatal flaws founded in inappropriate statistical methods and analyses, in addition to erroneous interpretations.
