“Wade repeatedly selected insect subpopulations for low numbers of adults per subpopulation”
Didn’t he in fact select sub-populations with low numbers of infants? Or am I misunderstanding completely.
The selection pressure is supposed to be lower adult populations, how many infants doesn’t really matter. Selecting on fewer infants (I assume you mean larva here—if not what’s the difference?) would force the expected result (restricted breeding of some kind) instead of allowing multiple potential paths to achieve the same goal. Falsification must be a possibility.
