Race, we are told, is a social construction, with no foundation in biology. We should see this as pc rubbish, since the same is now said about sex and gender. Surprisingly enough, it is not said about physical things such as alleged climatic change, which is oh so real and threatening for the Left. Surely, it too, must be a social construct, and therefore, not real, an illusion of society. Society is a god that for the radical Left magically creates the universe. Such a stupid philosophy for spoilt baby boomers.
Nevertheless, real science still struggles to produce research that shows the falseness of the Leftoid position. For example, a recent paper, A. Zaidi (et al.), “Investigating the Case of Human Nose Shape and Climate Adaptation,” PLoS Genetics, March 16, 2017, has confirmed the “Thomson Nose rule” (https://en.wikipedia.org/wiki/Arthur_Thomson_(anatomist)), that people in cold climates, such as northern Europe have longer tighter noses to humidify and warm air, while this is not needed in Africa, hence wider nostrils to cool air. Although this feature has been said to be purely random, due to genetic drift, these researchers refuted this claim by showing that the statistical variation could not be accounted for by chance alone.
Socially construct that!
