Interbirth intervals: Intrafamilial, intragenomic and intrasomatic conflict
Background and objectives: Interbirth intervals (IBIs) mediate a trade-off between child number and child survival. Life history theory predicts that the evolutionarily optimal IBI differs for different individuals whose fitness is affected by how closely a mother spaces her children. The objective of the article is to clarify these conflicts and explore their implications for public health. Me...

متن کاملIntragenomic conflict and cancer.
Intragenomic conflict occurs when some elements within the genome produce effects that enhance their own probability of replication or transmission at the expense of other elements within the same genome. Here it is proposed that mutations involved in intragenomic conflict are particularly likely to be co-opted by evolving lineages of cancer cells, and hence should be associated with the occurr...
متن کاملEcology drives intragenomic conflict over menopause
Menopause is the transition from reproductive to non-reproductive life well before natural death. Rather than involving a smooth, rapid change, it is normally preceded by a long period of erratic hormonal fluctuation that is accompanied by a plethora of unpleasant symptoms. Here, we (1) suggest that this turbulent period owes to conflict, between a woman's maternally inherited (MI) and paternal...
متن کاملInterbirth intervals in wild baboons: Environmental predictors and hormonal correlates.
OBJECTIVES Interbirth intervals (IBIs) are a key metric of female reproductive success; understanding how they are regulated by environmental, social, and demographic factors can provide insight into sources of variance in female fitness. MATERIALS AND METHODS Using 36 years of reproductive data on 490 IBIs for 160 wild female baboons, we identified sources of variance in the duration of IBIs...
