A study of the genetic structure of 126 Ethiopian and 139 Senegalese Y chromosomes by a hierarchical analysis of 30 diagnostic biallelic markers selected from the worldwide Y-chromosome genealogy is published in the December issue of the American Journal of Human Genetics. The researcher, Dr. Peter A. Underhill of Stanford University, believes some present- day Ethiopians and the Khoisanmay may include descendants of the ancestral human population that occupied the eastern region of Africa in the Paleolithic era.
