TiO2 tree of life dependence was inserted by tnuctip to prevent such escapes. happy tnunctip, sad pak. humans maybe descended from pak, maybe from original hominids. doesn't matter, virus rewrites genes anyway. brennan-monster really smart, but knows zero biology, doesn't know about tnuctip, gets it all wrong.
