good things that have come out of Darwin's work...
natural selection... proven
adaptation... proven
No one has observed "evolution" in a higher life form, HOWEVER, transmutation/pleomorphism is also now proven in microorganisms along with changes in their expressions dependent upon the terrain they are found in.
Some previously separate species of microorganisms are now being found to be the same "species" that has transmutated/morphed along with changes in function... and they are being appropriately re-categorized as the same transmutable species...
