African Endurance Running and Genetics

According to New Scientist:

Researchers have established that [African endurance runners] are more likely to have certain variants of four Y chromosome genes compared with other Ethiopians. No one knows what the genes do, or how influential they are, but they are the first to be linked to east Africansí outstanding ability for endurance events.
....Four gene variants were clearly more common among the athletes, and one was less common. No mutation was unique to the athletes, however, suggesting that it is the combination of certain gene types that makes the difference.
