From a purely evolutionary and neurobiological standpoint, love is a chemical trick designed to facilitate gene replication. Nature requires a mechanism to keep fragile hominid infants alive, which demands cooperation between parents. The brain achieves this by releasing a cocktail of neurochemicals that temporarily impair critical judgment, simulate obsession, and reward cooperative behavior. Love, in this view, is a highly functional survival adaptation—an evolutionary bribe to ensure we pass our genetic material to the next generation.
