what makes the gas come out of a valve fitted with a zero governor?
Probably the partial vacuum created in the venturi sucks the gas out of the governor ?
Strictly speaking a venturi is not a valve. And being pedantic it is a zero pressure differential governor. The gas at the outlet port is at the same pressure as the ambient atmosphere hence it has to be sucked out of the valve.
"Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction."As to your second point yes that's evolution in action

These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction."

That's just one of the five definitions of "evolution" in the Oxford Dictionary.
The second definition, which is relevant to the subject being discussed, is: "The gradual development of something."
And if you want to be really esoteric, try the mathematical meaning: "The extraction of a root from a given quantity."
