Today’s discussion question is: why do the lovebirds Sam and Jesse spend a lot of time together?
“Well,” someone says, “it’s because lovebirds’ brain reward centers are stimulated when they interact with their mate. Happy molecules trigger happy receptors, and the birds get happy. So they seek out that reward.”
“No,” someone else says, “it’s because a lovebird that interacts with its mate more has a stronger pair bond, making it less likely to be cuckolded. Lovebirds who spend more time with their mates have more chicks and so pass more genes on to the next generation.”
