The dating show is a constantly evolving creature. The latest variation on the species: NBC's Age of Love (premiering June 18), which adds a creepy ''cougars vs. kittens'' twist. How did we get here? Our hand flowchart explains.

The Dating Game on steroids: 25 hotties live together and are jettisoned one at a time by a handsome man on a ''journey.''
AVERAGE JOE (2003)
It's Bachelorette with a twist: A gorgeous woman had to choose between nerds and studs. Shocker: She usually chose the studs.
JOE MILLIONAIRE (2003)
A ripped, blue collar hunk posed as a rich heir, while a group of gold-digging catfighters desperately tried to win his love.
