To make it easier to make shields which use i2c the manufacturer added the sda/scl pins in a known location. With i2c there are 2 wires referred to as scl and sda. The latest arduino uno r3 was released in 2011 and it is the third revision of uno boards.

The 2 first pins side to usb connector are sda/scl according to documentation.
