THE CHANGING colour of skin is part of an evolutionary process. But that’s not the most important discovery a recent landmark study revealed on skin colour diversity. Tracing the evolution of genes and how they travelled around the world, a team of international scientists found that a large proportion of African origin people had gene mutations that are responsible for lighter skin. Two genes, HERC2 and OCA2—associated with light skin, eyes and hair in Europeans—arose in Africa, says the study published in the Science journal. In fact, people in Africa have almost every skin colour on the planet—from deepest black in South Sudan to beige in South Africa. Developing skin colour is also a biological process. This evidence should have come as the last nail in the coffin, especially for those practising and propagating the science of race and spreading race in the name of colour.
But it did not. The chain of brutal killings of black people by the white US police officers—including George Floyd who was choked under the knee of the white police officer—has shocked the world and ignited an unprecedented wave of anti-racist demonstrations. In the US, protesters clashed with the police in many states and the National Guard was called in; many states declared “police-free” zones in public areas; and, now police reform bills are being debated in the US Senate.
As he began his campaign for re-election this month, US President Donald Trump called the black protesters “anarchists, looters and other lowlifes” triggering racial tensions. Similar statements during his 2016 election campaign had set in motion an avalanche of racial conflicts that helped him to consolidate his core “white” vote-bank.
