Twilight Divorce: A Genetic Perspective

The provided text explores the rising trend of "twilight divorce" and proposes a biological explanation rooted in human genetics. It posits that initial romantic attraction often stems from a genetic predisposition to seek partners with dissimilar genes, as this maximizes offspring survival. While this genetic strategy facilitates procreation, the text argues that these very differences, once a source of attraction, can become sources of conflict and incompatibility later in life, particularly after the child-rearing phase concludes. Ultimately, the source suggests that "twilight divorce" might represent a shift from a gene-driven reproductive strategy to a need for emotional companionship, highlighting the dual roles of a spouse as both a reproductive partner and an emotional companion, roles not always fulfilled by the same individual throughout a lifetime.
