Instead of singularly focusing on the failings of the extended family system, it should be openly acknowledged that most children continue to be cared for by their extended kin — albeit by their maternal kin.
There is some evidence to suggest that this avoidance behaviour occurs through a kin recognition system [ 37].
There is overlap in the ecological and life history correlates that each theory predicts for example, strength of interaction among kin, breeding system, extent of parental care but we have at least some ability to discriminate between theories based on such data.
Results are discussed in terms of plasticity of kin recognition systems, the costs and benefits of maintaining social memories, and the contexts in which templates are updated.
All 18 genera were either eudicots or monocots and included the quintessential model organism Arabidopsis thaliana., Detection of kin recognition systems included split-root designs (both owner and sharer scenarios),,, - ramet-pair designs including some pots with kin and other pots with non-kin, introduction of root exudates,, and introduction of volatiles.
The northwestern coastal provinces, where partible inheritance was practiced and kin ties were relatively weak compared with other regions, are coded as nuclear family systems.
In addition to kin discrimination, this system also relates to sex allocation: female M. australica do not allocate sex in response to superparasitism, instead they consistently produce males at a low rate, which will reduce the mortality caused by fighting between brothers (Abe et al., 2005).
Moreover, elimination of a kin-based donation system will require a re-engineering of social values in Pakistan regarding the purity of biradari blood a long term proposition if it is possible at all.
Such parasitism exploits the limits of an evolved system of kin detection.
