So what
This chapter contains Harari’s scientifically strongest claim (no biological basis for racial/caste hierarchies) alongside his weakest framework (‘biology enables, culture forbids’). The no-biological-basis claim is backed by decades of genetic research and has only gotten stronger. The patriarchy-as-universal claim is overstated but directionally defensible. The biology/culture framework is unattributed and philosophically problematic.
