A new study suggests that cultural forces-such as technology, medicine, and social systems-are now shaping human evolution more than environmental pressures. Researchers from the University of Maine say this shift could be accelerating, as cultural solutions to survival challenges reduce the need for genetic adaptation.
"Cultural evolution eats genetic evolution for breakfast," said evolutionary ecologist Zachary Wood. The research highlights how innovations like cesarean sections and medical advances have lessened the impact of biological constraints on survival.
The study proposes that human traits are increasingly influenced by cultural systems rather than genetics. This transition may lead to a future where societal structures and technological progress play a greater role in determining human development.
