[[There is nothing in any biology book that demonstrates mutations anticipating need.]]
Nope- there sure isn’t- mutaitons are incapable of anticipation- And I didn’t state you can find someone stating the word anticipation (although you might IF you run across someone intellectually honest enough to call a spade a spade instead of an elephant). You can find examples of htis anticipation IN THE CELL networks and how they REACT to mutations, and how it affects the WHOLE system and how cells reactions trigger other cells reactions and so on and so forth. Even Miller talked abotu this unwittingly in his blood clotting intelligently designed explaination for how clotting could ‘naturally evolve’
Reaction isn't anticipation.
