Description:
To learn the evolutionary trajectories of caste differentiation in eusocial species is a major goal of sociobiology. We present an explanatory framework for caste evolution in the eusocial wasp genus Polistes (Vespidae), which is a model system for insect eusocial evolution. We hypothesize that Polistes worker and gyne castes stem from two developmental pathways that characterized the bivoltine life cycle of a solitary ancestor. Through individual-based simulations, we show that our mechanistic framework can reproduce colony-level characteristics of Polistes and, thereby, that social castes can emerge from solitary regulatory pathways. Our explanatory framework illustrates, by specific example, a changed perspective for understanding insect social evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2408871/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2408871/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunt, James H -- Amdam, Gro V -- P01 AG 22500/AG/NIA NIH HHS/ -- P01 AG022500/AG/NIA NIH HHS/ -- P01 AG022500-03/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2005 Apr 8;308(5719):264-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Missouri-St. Louis, One University Boulevard, St. Louis, MO 63121, USA. jimhunt@umsl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15821094" target="_blank"〉PubMed〈/a〉
