Fantastic article by Katherine Reynolds Lewis. Two questions:
- Evolution in humans takes more than 300 years. How credible is the theory that behavioral changes wrought by the Industrial Revolution could have such a stark and sudden impact on skull size, jaw shape, and other physical characteristics of humans?
- Conversely, could a massive increase in chemical and industrial exposure be more likely to cause these changes? The skyrocketing number of cases of nut allergies, for instance, appears likely to result from this exposure.
I would welcome feedback from Katherine as well as other wise commentators, such as Christopher Yerington and others.
