The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania. Genetically unique populations that once existed in Nigeria, Cameroon, Chad, Eritrea, Ethiopia, Somalia, Mozambique, Malawi and Angola have disappeared. The origins of the ‘genetic erosion’ coincided with colonial rule in Africa and the popularity of big game hunting. From the second half of the 20th century, however, poaching for horns has dramatically depleted their population and genetic diversity, especially in Kenya and Tanzania.<\/b><\/p>\n Question 1<\/strong>:<\/p>\n What is important for evolution?<\/p>\n a) Genetic variation Question 2:<\/b><\/p>\n Sub Sharan Africa has lost how many black rhino genetic lineages in 200 years?<\/p>\n a) 64 Question\u00a03: a) Tanzania SSC CGL Syllabus PDF<\/a><\/p>\n Take SSC CGL Free Mock Test<\/a><\/p>\n Question\u00a04: a) poaching Question 5: a) species population Solutions: 1 to 5<\/b><\/p>\n 1) Answer (a) 2) Answer (c)<\/b> The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania.
