Speed dating procedure

When men rotated, women (the ones sitting) were more selective.

In half of the events, the men rotated while the women sat and in the remaining events, it was the women who rotated (a procedure nearly unprecedented in professional heterosexual speed dating events).

They corralled 350 college students into 15 speed dating events for their study.

Participants went on 4 minute “speed dates” with approximately 12 opposite-sex individuals during each event.

You would think that they then happily settle for the remainder of the short Arctic breeding season. Soon after their arrival on the tundra, they start to defend display territories and enter a fierce competition with other males for copulatory access to fertile females.

Our earlier work showed that males compete around the clock in this continuous light environment.
