Many American universities will exclude any professor who questions evolution. They will kick him or her out of the university. Evolution is too weak of a theory to survive honest inquiry.
Macro-evolution presumes that all life descended from early single-celled creatures. But in order to prop up macro-evolution the biology texts must use several examples of micro-evolution (i.e. genetic remnant variation), which is not evolution at all.
Charles Darwin himself stated it was merely a theory. The proof that is shown isnt proof at all. All discoveries on or against this matter are also not fully disclosed to anyone or those being taught. Biologists are now stepping forward and speaking up about this. If they disagree then why continue to teach this to our kids?
