Hindus (DNA F) voluntarily left Somalia and moved to Gujarat 60,000 years ago. They followed the Indian monsoon winds that blew from the Arabian Sea to the Bay of Bengal. The monsoon winds reversed direction every 20,000 years due to the Earth's rotation around the Sun, called Axial tilt. When the winds reversed, fertile land became wasteland and wasteland became fertile land. Hindus were forced to move from one fertile land to the next every 20,000 years. The F in Gujarat was split 40,000 years ago and moved out in different directions. Every 20,000 years they were forced to relocate. The last relocation took place 4,000 years ago. The 2011 Census collected detailed data on more than 2,200 dialects. An analysis of the dialects provided accurate migration paths of the F and the four subgroups H, L, J2b, and O.
