[Green Lantern] Why is it so many humans are chosen to join the corps?

Are  humans just that willful of a species compared to others in our sector? Also are there other species out there that get so many chosen from their ranks to join the Corps?

This is a relatively new phenomenon. Prior to Hal's joining no human had ever been selected into the corp. With his great success it is speculated that the rings/guardians have decided to test more humans to see if humans in general can be that successful. Additionally Kyle's selection was more from desperation rather than design.

As far as other species are concerned it is highly rare to have so many of a species in the core at the same time, but many species have histories stretching back millennia of Lantern membership. So countless species have had many more lanterns than the measly 5 that the humans have produced.
