The 2001 standards encourage teachers to evade tough questions from students about the validity of evolution theories. Each sheet of toilet paper equals 100 million years. It gets worse. For example, the idea that sunsets are beautiful is not scientific unless some procedure is contemplated to determine whether or not sunsets really are beautiful. On the other hand, a theory that the sun rises in the east is falsifiable because it could be disproved by the sun rising once in the west.
Evolution can encounter difficulties with the falsification test.
Much of what is taught as evolution in the schools is not falsifiable at all and, thus, cannot truly be called science. One car of any color, but black and only one time. No matter how much evidence seems to support a theory, it only takes one proof that it is false to show it to be false. Evaluate the validity of results and accuracy of stated conclusions. Obviously, that definition is so vacuous that it is both meaningless and incapable of the falsification test.
