DESCRIPTION:Ludovic Maisonneuve ( IAST)\, “When to learn from elders or pee
 rs: unraveling the factors shaping the evolution of exemplar age choice”\,
  IAST Lunch Seminar\, Toulouse: IAST\, March 20\, 2026\, 12:45–13:45\, roo
 m Auditorium 4 (First floor - TSE Building).\n\nIn many animal species\, i
 ndividuals acquire knowledge from others that enhances their survival and 
 reproduction. However\, among the many available exemplars\, not all provi
 de reliable information. Consequently\, individuals tend to choose their e
 xemplars selectively. One widespread pattern is a preference for older ind
 ividuals\, who may have accumulated valuable knowledge over their lifetime
 . Yet empirical studies also show that individuals frequently learn from p
 eers of similar age\, suggesting that copying elders is not universally op
 timal. What ecological and social conditions favor learning from elders ra
 ther than peers\, therefore\, remains unclear. \n\nHere\, we investigate t
 he evolutionary drivers of age-biased exemplar choice in age-structured po
 pulations where individuals accumulate knowledge over their lifespan. We s
 how that the evolution of exemplar age choice is shaped by a trade-off bet
 ween targeting knowledgeable individuals and accessible ones. This trade-o
 ff leads to learn preferentially from relatively young exemplars\, who are
  common and still able to provide substantial amounts of novel knowledge\,
  given learners’ limited knowledge at early ages. As individuals age\, enc
 ountering exemplars with substantially novel knowledge becomes increasingl
 y difficult. Consequently\, as they get older\, individuals are expected t
 o shift toward learning from older individuals\, who possess more knowledg
 e. Population\, environment\, and knowledge characteristics can shift this
  balance\, generating a wide range of strategies from learning primarily f
 rom peers to consistently targeting the oldest individuals.
