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 species to survive and reproduce, explains lead author Yoshan Moodley, 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 lineages remain, says the paper. 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.

It was a bittersweet moment for me when I found out that I had been selected for the Sakura Science Exchange programme, a Robotics and IoT workshop in Japan. A fully-funded opportunity of a lifetime. Fly off to Saitama without a care on the world, and all I had to do was put into practice what I love to do – computer science. The bitter part of the episode – that I would lose two weeks of IB education, an almost literal mountain to cover when I got back – was quickly forgotten when I envisioned myself programming robots in the country that gave us Anime and sushi! It was with the eagerness to have an extended vacation in an un-visited land, and the opportunity to learn more about a subject that I am passionate about, that I headed to the Kempegowda International Airport outside Bengaluru. Little did I know this would be the experience of a lifetime, more for the endearing values of the Japanese culture that made their mark on me than anything else. The first feature of Japanese society that called out to me was the Discipline. Walking into the Narita International Airport, used as I was to the noisy crowds back in India, I quite literally lost my breath to the sight that awaited me. Be it the security check or baggage claim, somehow there was a silence that felt right. Everyone went about their activities without any confusion. And, contrary to the bharatiya custom of lazy pot-bellied officials, every guard and all counter personnel did what they were supposed to do to ensure this flow was maintained.
