centipedes and roaches are insects not animals (unless this whole time ive been wrong)
many animals however are, yes, not close in biological and neural complexity, but im PRETTY sure scientists know this and in fact tested on animals close to us (monkeys, pigs, etc). Im pretty sure nobody is retarded enough to make a conclusion by testing on centipedes and roaches.
using roaches and centipedes as examples is taking it to way extremes.
