I use urines all the time to "calm" animals near my sets. Trapping. When I started bowhunting in the early 70s EVERYBODY used some kind of deer lure - they dragged deer pee soaked rags walking in and a bunch of other stuff. Lures are less popular now with the bait and food plot expansion 90s through now - but for a decent woodsman I think good lures have their place. Smokeys and James Valley are legit - I'd say most stuff over the counter is snake oil - but good stuff - used correctly - with a plan - WILL work. But answer to how they figured that out - It was trappers who figured it out. Urine has a calming effect on most animals, I've seen enough results to prove it to me.
Good Hunting<><
