Two Researchers Say Humans Are In the Midst of an Evolutionary Shift Like Never Before. But Not Everyone Is Convinced

Key Points:

• Researchers Timothy Waring and Zachary Wood propose that human evolution is increasingly driven by cultural inheritance rather than genetic changes, with cultural systems like medicine and technology enabling faster adaptation than natural selection.
• They suggest humans may be transitioning toward a cultural "superorganism," where societies function as integrated evolutionary units similar to ant or bee colonies, relying heavily on shared institutions and cooperation.
• A peer-reviewed critique by Nejad Kourki challenges this view, arguing that human societies lack the autonomous group-level reproduction necessary to qualify as evolutionary individuals in the same way multicellular organisms or eusocial insects do.
• Waring and Wood acknowledge their hypothesis is speculative and emphasize that cultural evolution's dominance does not guarantee a completed transition to a superorganism or imply moral progress in societies.
• Ongoing empirical research aims to test the hypothesis by measuring the relative contributions of cultural versus genetic inheritance to human evolution, but definitive evidence for a major evolutionary transition remains lacking.
