Lemur lovers' synced scents reflect strength of their bond

Lemur lovers spread their scents by rubbing glands on everything from tree trunks to their partner. Researchers discovered that the more similar a lemur couples' scents, the stronger their bond. This could be a way to coordinate marking territories, or to display their relationship status to the rest of the group. Lemurs are an endangered species, so learning about mating techniques could be essential to their preservation.
