Species divergence in offspring begging intensity: difference in need or manipulation of parents?

Proceedings. Biological sciences - 7 Apr 2007

Qvarnström Anna, Kehlenbeck Jenny Vogel, Wiley Chris, Svedin Nina, Saether Stein Are

Abstract excerpt

Conflicts over the delivery and sharing of food among family members are expected to lead to evolution of exaggerated offspring begging for food. Coevolution between offspring begging intensity and parent response depends on the genetic architecture of the traits involved. Given a genetic correlation between offspring begging intensity and parental response, there may be fast and arbitrary divergence in these...
