The standards seem clear on this at first reading but the argument concerning falsification belie this seeming understanding 3. The creationist majority failed to understand that science is about investigating physical causes and thus supernatural explanations have no place in science. If they understood this they would have accepted the standards as presented with evolution in place. There would be no debate, just as there is no debate about discussing chemical reactions in the body, treating it from a scientific viewpoint as a complex chemical machine. The creationist majority fell into the logical trap that just because we can't prove a hypothesis or a theory that there is no way to deal with that theory in a scientific way.
Scientists make judgments about the likely truth of a hypothesis or theory all the time.
We can't see electrons but we have elaborate and successful theories about how they behave. The creationist majority has been seduced by a simplistic notion of falsifiability that says only one falsification is sufficient to cause rejection of the theory. A theory is not a simple statement about the universe but a complex of hypotheses along with assumptions about a phenomenon or set of phenomena. Theories are not by their natural perfect and a seeming falsification may cause a modification of a theory rather than rejection. The creationist majority does not understand the importance of modern theories choosing instead to cleave to a clearly wrong idea that theories are not important and that technology can develop without theory.
