Is it valid to treat theories as scientifically checked phenomena? I, for instance, take scientific testing seriously. Before you get on a plane, engineers have already done tests in laboratory 🧪 to work out 🏋️ how many cycles 🚲 every part on a plane is meant to go through before replacement (meaning how many flights ✈️). So I value when someone in a university somewhere has looked at a theory to check it, even if I like or dislike the outcome.

So here’s the thing! Scientists have looked at head shape and skin pigmentation to find out if they are independent traits or connected phenotypes. What did they find?

Head shapes alone are insufficient to classify someone as “negroid” or to categorize any race because cranial morphology (head shape) and skin color are influenced by independent genetic traits. Studies in population genetics have shown that the genes responsible for skull shape variation and those affecting skin pigmentation are located on different parts of the genome and evolve under different selective pressures. For example, cranial shape is influenced by factors like climate adaptation, diet, and population history, while skin color primarily adapts to UV radiation levels. The concept of using head shape to define race is outdated and rooted in 19th-century racial theories that have been debunked by modern genetics. Genetic variation within so-called “races” is often greater than between them, highlighting that phenotypic traits like skull shape do not align neatly with simplistic racial categories or skin color.
