Flies are flies generation after generation .....always flies :
It is a striking, but not much mentioned fact that, though geneticists have been breeding fruit-flies for sixty years or more in labs all round the world- flies which produce a new generation every eleven days-they have never yet seen the emergence of a new species or even...... a new enzyme .
