Quick takeaways

  • The study reveals that traits associated with whiteness, including skin and hair type, have evolved significantly due to historical environmental and social pressures.
  • Socioeconomic changes since the Industrial Revolution have shifted genetic selection pressures, impacting body fat preference and educational attainment across generations.

Deep dives

Evolution of Skin Color and Hair Type

The concept of whiteness is presented as a relatively modern evolutionary trait, having significantly developed in the last 6,000 years. Historical genetics suggest that the lighter skin associated with whiteness was not as prevalent 4,000 years ago, as genes for darker pigmentation were more common. Additionally, hair types have shifted over time, with straighter hair becoming dominant in European populations and a notable rise in baldness emerging as well. This evolution reflects genetic selection pressures influenced by environmental changes and social dynamics throughout history.
