Professing themselves to be wise, they became fools,
Romans 1:22
"Do you accept that if hypothesis A readily explains an empirical fact F and hypothesis B does not, 
Do I accept Torley's logic? Yes. Do I think common descent is explanatory (A) and design is not (B)? No. Do I think that common descent is predictive (A) and design not (B)? No. The reason is that the syllogisms cut both ways. Design is both explanatory and predictive, particularly when dealing with pattern breaking observations in biology, where common descent doesn't work as an explanation. Thus the onus of proof is not on design alone, as Professor Swamidass thinks, but on common descent as well." EN&V
