No.<quoted text>Stem cells are evil!
Science is almost constantly wrong? Yeah. We imagined all that stuff about transistors, gps systems, the mars rovers, etc. It is to be expected that mistakes will be made, but the entire point of the scientific method is that these mistakes are eventually weeded out. Should we refuse to teach anything until we have gained omniscience and we know that every piece of knowledge we have is irrefutable truth?
Unless it's an irrefutable truth, it should not be in any science book presented as an irrefutable truth.
