DESCRIPTION:Luis Santos-Pinto\, “How Economic Exchange Shapes Human Genetic
  Diversity”\, IAST Lunch Seminar\, Toulouse: IAST\, March 14\, 2025\, 12:4
 5–13:45\, room Auditorium 4 (First floor - TSE building).\n\nBy expanding 
 the value of what individuals produce\, economic exchanges are recognized 
 as driving the wide diversity of economic activities seen in human societi
 es.  Since productivity depends on both chosen roles and innate abilities\
 , we ask whether exchange could have influenced human evolution by promoti
 ng genetic diversity. We model a system where individuals produce and exch
 ange goods under Walrasian equilibrium\, with abilities determined by an e
 volving genetic trait. Using the adaptive dynamics approach\, we analyse h
 ow exchange shapes evolutionary pressures on this trait. Our analysis demo
 nstrates that exchange consistently promotes the maintenance of genetic di
 versity through negative frequency-dependent selection\, and that it can g
 enerate stable polymorphism when the production of goods requires differen
 t abilities. Importantly\, we establish that the mode of exchange matters:
  markets\, where individuals can switch trading partners\, promote genetic
  diversity under broader conditions than when exchange occurs in isolated 
 pairs. Finally\, we show that genetic diversity and economic specialisatio
 n can co-evolve\, each facilitating the emergence of the other under a wid
 er range of conditions. Our findings suggest that economic exchanges play 
 a crucial role in fostering biological diversity and offer insights into h
 ow a cultural phenomena\, here economic systems\, may have shaped human ev
 olution.
