DESCRIPTION:Speaker: Jacobus J. Boomsma\nAbstract: Major transitions in evo
 lution shift selection to a higher level. Some require high\nrelatedness (
 multicellularity\, eusociality) and some do not (obligate mutualisms\,\nse
 xual partnership). I will argue that strict\, life-time commitment between
  partners\n(gametes\, parents\, somatic cells\, and families) appears to b
 e a very general\nrequirement for realizing major transitions. It captures
  high offspring relatedness\nfollowing sexual partner choice and it produc
 es analogous alignments of\nreproductive interests when mutualistic partne
 r choice is “supra-sexual”. Life-time\ncommitment is very difficult to a
 chieve in nature\, but all eukaryote life is somehow\nbased on it. As it s
 eems\, life-time commitment does not remove all reproductive\nconflict\, b
 ut enough of it to allow lineages to diversity and become ecologically\nsu
 ccessful. Fungus-farming ants and termites have proven to be good models f
 or\nstudying questions of partner commitment and will continue to offer ri
 ch\nopportunities now that sequenced genomes are becoming available.
