Scientists have long understood that in these species, reproductive performance is influenced by pair-bond
strength and longevity, with long-established pairs usually better at rearing offspring.
Conquering the divide and mating with a female after just six hours of her company can form a lifelong pair-bond
There were all of these theories about how and why we pair-bond

They can pair-bond
and set up nesting, which we call housekeeping.
But what fundamentally distinguished BSD from all other theories of, or perspectives on, early experience and human development was the explicitly-labelled <<uncanny prediction>> that these developmental experiences and psychological orientations would influence somatic development by affecting the timing of puberty; and that this cascade of developments shaped, in adolescence and adulthood, sexual behavior, pair-bond
orientation and parenting.
