what do you mean "ought"??
it is an empirical question and there is no reason to suppose that anomalies
pop up when the data is looked at.
i saw a study recently that makes my point.
there was a bad famine in the netherlands that ended in may of 1945.
babies born before may had a low probabiliy of being fat.
those born 3 months after may, had a very great chance of being fat. The
genes are the same, but what happened in the womb affects each of our lives.
