Did I hear "predictive power"?
Behold...the Predictive Power of the ToE:
"Some things changed in some ways sometime; some thing may change."
Uh yeah, whatever.
The Theory of Evolution through natural selection has made many predictions that have been born out including the fact that in genes under high selective pressure the majority of mutations would be CONSERVATIVE mutations (i.e. those that do not actually change which amino acid gets incorporated into the protein that the gene codes for).
Just one of THOUSANDS of predictions that have been substantiated from this highly useful theory.
Learn something.
