DNA tests showed that we, all humans on this planet, are all descendants from just one family. But that one not only lived several ten thousand years ago, they were also Africans. But it shows: We are not that different. We all belong to one race, the Homo sapiens. So for people who are afraid about immigrants: We in Europe, Asia, America, Australia are all immigrants! Our ancestors came from Africa.

While it is obvious that people in countries near the equator, where the radiation from the sun is strong, have dark till nearly black skin, for a long time I was wondering why Europeans and East Asians have lighter till nearly white skin. In evolution nothing happens without reason. So: The human body needs Vitamin D which it can get from sunlight, but there is not so much sunlight in northern countries (and it is raining often and dark skin doesn’t let much sunlight through, so it is an advantage to have white skin. So the natural selection of the evolutionary process caused the descendants of those people who moved from Africa to Europe to get a lighter skin colour.

When humans moved from Africa to the Fertile Crescent and began settling down and farming, developing unicorn into different useful grain species – That was the moment people could have begun to become vegetarians and live peacefully along other animals! But they continued killing and eating animals just out of habit and actually selfishness, and that lasts till nowadays.
