Monogamous social systems began evolving in some primates around 16 million years ago, emerging from promiscuous mating systems similar to those of chimpanzees and bonobos (Opie, 2012).

In stark contrast, the genomes of Homo sapiens from …

In animal communication natural selection favors callers who vocalize to affect [i.e. manipulate] the behavior of listeners and listeners who [are selected to] acquire information from vocalizations. . . . Whereas signalers may vocalize to change a listener’s behavior, they do not call to inform others. Listeners acquire information from signalers who do not, in …
Causal narratives seek to knit together disparate observations, facts, and events into a coherent and inclusive whole that convincingly links later events to prior events.
