The roots of Course of Nature entered the music scene with the singer, Mark Wilkerson, and guitarist, John Milldrum, in the band Cog. The band only released one album when Mark and John were involved, No Time At All, in March of 2001. After this they decided to leave the band and head in their own direction. Rickey Shelton joined them and they recorded an album. Their name is rather interesting due to the fact that while they had originally picked the name "Pull", they decided on the name "Course of Nature", which had been a track on the album Cog had earlier released.
