But only Homo sapiens had the other features (larynx, Broca’s area??) that allowed an initial “programming event” to be passed on to others vocally; i.e. not the slow route of passing a successfully mutated allele to the next generation sexually.

Just noticed this. Are you saying that only humans have a larynx? What is a vocal programming event?
