In the year 1839 a British zoologist named George Robert Waterhouse found an elderly female hamster in Syria. After this discovery, there wasn't much more found out until a century later. In 1930, Israel Aharoni, another zoologist, found a female hamster and her litter of pups in Syria. Most hamsters in captivity today are believed to be descendents of this litter.
If the 1 year old hamster is a syrian hamster DO NOT put another hamster with it. They are hamsters that NEED to be alone. If it is a dwarf, hamster, it might be ok. Dwarf hamsters like having each others company. However, if the 1 year old hamster is not use to other hamsters, it might not go over to well.
The original creator of the catchy little tune called Hamster Dance was a Canadian art student by the name of Deidre Lacarte. It was created for a Geocities page.
If you see the hamster looking and nibbling for a place to get out, then they want to get out. I found this answer because my own hamster escaped. 
Well, it depends if they found each other. But if they did, I think that they would just fight each other. Not mate, lol
