E tardigradis Asinis Equus non prodiit.

The horse is not the progeny of the slow paced ass, the sheep of the lion. We do not easily believe a dull and stupid man to be the son of an acute, sensible and ingenious parent; a coward, of a brave and spirited, or a debauched and worthless man, to be the progeny of a good and worthy sire; and yet these anomalies not unfrequently occur.
