Why Universal Common Descent is a Non-Starter

-
EvoTARDs, like those running and commenting on TSZ, are clueless losers. They actually believe universal common descent is a scientific concept even though given starting populations of prokaryotes they don't have a mechanism capable of getting beyond more populations of prokaryotes! UCD is a non-starter in reality and scientifically.

So where did Theobald and others go wrong? They posited an untestable concept. Not only that they don't even have a mechanism- Theobald's evidence is minus any mechanism- and he ignores common design because he is most likely ignorant of the concept- which is very common for the evoTARDs.

So to be clear the evidence for universal common descent assumes it is true and then shoe-horns the evidence to fit it.
