The monophyly of eukaryote STC homologues could be explained by vertical inheritance from a common tetrahymanol-synthesizing eukaryotic ancestor. However, if this were the case, dozens of parallel losses of the STC genes in many eukaryotic lineages that currently lack this gene would be required, so this evolutionary scenario seems unlikely. An alternative and more plausible possibility is that the STC gene has been laterally transferred among phylogenetically diverged eukaryotes through an unknown mechanism.
An unknown mechanism? That’s right, evolutionists must appeal to unknown mechanisms to explain their “fact.” We don’t know how evolution happened, but we’re certain that it’s true. Take another drink. As one evolutionist who reviewed the paper wrote, “There is nothing to criticize.”
Nothing in biology makes sense in the light of evolution.
