Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a speciesto survive and reproduce, explains lead author YoshanMoodley, Professor at the Department of Zoology, University of Venda in South Africa. 

Two centuries ago, the black rhinoceros – which roamed much of sub Saharan Africa – had 64 different genetic lineages; but today only 20 of these lineagesremain, says the paper. The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania. Genetically unique populations thatonce 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 hasdramatically depleted their population and genetic diversity, especially in Kenya and Tanzania.

The correct answer is c) 44. The passage states that there were originally 64 different genetic lineages of the black rhinoceros, and now only 20 remain. Therefore, 64 - 20 = 44 lineages have been lost.

Genetic Lineages Lost in Sub-Saharan Africa
Sub-Saharan Africa has lost a total of 44 black rhino genetic lineages in the span of 200 years.

Explanation:
- Two centuries ago, the black rhinoceros in sub-Saharan Africa had a total of 64 different genetic lineages.
- However, today only 20 of these genetic lineages remain, indicating a loss of 44 lineages over the years.
- This significant reduction in genetic diversity is a cause for concern as it can impact the species' ability to survive and reproduce.
- The decline in genetic diversity can be attributed to factors such as colonial rule, big game hunting, and poaching for horns, especially in countries like Kenya and Tanzania.
