[PHOTOS] Love Is In The Air With Lemurs, Duke Study Finds

Lemur couples with infants start to smell alike. Oh sure, they smelled differently before they had offspring. But pretty soon, the lemur lovers start mirroring each other's scents. Even their "scent-marking" odor begins to change. Researchers think the change in scent could be a way to mark territory, or it could be a way to advertise their relationship to all the other would-be mates.

The study findings are in the  February issue of  Animal Behavior.

"Surprisingly," researchers say "the number of years a couple had lived together made no difference to their mating success or the similarity of their scents."
